Market hall III

The market hall III in the Berlin Friedrich city built in the first phase of the municipal building program for the market halls 1884-1886.

The small market hall , in conjunction with the central market hall on Alexanderplatz and the other small market halls, was supposed to ensure that the constantly growing population of Berlin was adequately supplied with cheap and unspoiled food and to free the streets and squares from the weekly markets , which were increasingly perceived as unsanitary and a traffic obstacle . The hall closed in 1910 because it was unprofitable and then housed the Berlin concert hall Clou , where Adolf Hitler appeared for the first time as a speaker in Berlin on May 1, 1927. At the end of the Second World War , the building complex was largely destroyed. The existing front building is now a listed building and was extensively restored in 2006.

overview

Markthalle III was on Zimmerstrasse 90/91 and Mauerstrasse 82 in Friedrichstadt in the Berlin newspaper district ; the front building that still exists today is on Zimmerstrasse. The building was part of the construction program for a total of 14 Berlin market halls, which were built between 1884 and 1892 in three construction phases. City planning officer Hermann Blankenstein and his office drew the plans for the market hall, which was built between 1884 and 1886 in the first phase, as for all other halls.

The change in Friedrichstadt from a residential to a business district and the associated decrease in the residential population made the operation of the market hall unprofitable. The Berlin magistrate closed the market hall and leased it on April 1, 1910, initially for 15 years to the catering company Hoffmann & Retschlag , which had it converted into the Berlin concert hall Clou in 1910 by the architect Johannes Kraaz . The largest entertainment venue in Berlin at the time was used not only for concerts but also for political events such as the aforementioned Hitler appearance.

After the property was divided up and sold to the former tenant Hoffmann & Retschlag and the Franz-Eher-Verlag , which set up its Berlin branch on Zimmerstrasse, at the end of the 1930s , the editorial offices and printing works of various Nazi propaganda magazines moved into the front building on Zimmerstrasse. The war caused enclosed pleasure ground served in February 1943 during the Fabrikaktion as a transit camp for Jews arrested prior to deportation . At the end of the Second World War, the market hall complex was destroyed except for the front building on Zimmerstrasse.

The listed remnant of the once extensive market hall is a reminder of the efforts to provide food for the Berlin population in the 19th century, of the night life and entertainment culture before the Second World War, but also of the dark chapter of German history under National Socialism .

Construction phase and opening

Market hall III (marked by the blue circle) and its surroundings on a city map from 1896

The planned market hall II on the corner of Lindenstrasse and Friedrichstrasse alone could not meet the needs of the densely populated Friedrichstadt. For the construction of the second market hall in Friedrichstadt, the city of Berlin acquired the properties at Mauerstrasse 82 and Zimmerstrasse 89-91 for 850,600 marks in May 1883  . After the approval of the city ​​council on May 21, 1884 for the plans submitted by the magistrate for market hall III, construction work began on July 23, 1884. In October 1884, however, the preparations came to a halt due to a conflict between the magistrate and the royal police headquarters . For all market halls, the Presidium called for the wooden roof to be divided into four-meter-wide, non-flammable strips into segments of a maximum size of 1,600 square meters and the passages through the front buildings and portals to be widened to nine meters. The widening of the passages was not possible, at least for the passage on Mauerstraße, because the width of the property on the street was too narrow. The work stopped on October 20, 1884 was suspended until the decision of the Minister of the Interior on April 22, 1885, the majority of which was in favor of the magistrate.

Market hall III was handed over to its intended use on May 3, 1886 and opened at the same time as the central market hall on Alexanderplatz and the other small market halls of the first construction phase. Markthalle III replaced the weekly markets on Gendarmenmarkt , Dönhoffplatz and Potsdamer Platz , which were closed. The construction and furnishing costs for the market hall and the front building on Mauerstrasse totaled 644,267 marks. The cost of the front building on Zimmerstrasse was borne by the Städtische Sparkasse, which set up its business premises in it.

The building plot

The irregularly shaped parcel with the ground floor plan

The irregularly shaped building plot consisted of a 37.31 m × 46.14 m rectangle along Zimmerstrasse. The parcel of 13 meters in length on the street front and 37.24 meters deep, referred to in the adjacent floor plan as the "sold building site", was separated from the originally purchased property on the east side and sold as Zimmerstrasse 89 expensive area of ​​the city center and relieved the strained budget for the market hall building program. This was not a restriction for the market hall built on the rear of the plot, as the remaining width on the street was by far sufficient for the front building and the passage.

This was followed by a 59.60 m × 98.45 m rectangle with a "cut off" corner. This border line, roughly from the middle of the northern to the middle of the eastern side, roughly followed the course of the Mauerstraße. In the middle of this inclined boundary line was the narrow, 45.95 meter deep wedge-shaped property at Mauerstraße 82, which was 16.9 meters wide at the rear property boundary and whose width of 5.13 meters at the street was just enough for the passage to be created was enough.

The market hall complex

With the market hall inside the property and the two front buildings with the passageways, the market hall complex shows the typical elements of the halls of the municipal building program, which were not built as free-standing halls. Hermann Blankenstein often planned the front buildings as mixed residential and commercial buildings with shops on the ground floor and apartments on the upper floors. As a special feature of Markthalle III, a further municipal construction project was carried out with the branch of the Städtische Sparkasse in the front building on Zimmerstrasse next to the Markthalle.

The front building on Zimmerstrasse

House, courtyard, side wing and passage

The passage with the ribbed vaults designed with light yellow and light red clinker bricks and shaped stones

On the property at Zimmerstrasse 90/91, a four-story, 13.8-meter-deep front building with two side wings of 8.87 meters on the western and 9.08 meters on the eastern property line was built at the expense of the municipal savings bank . In addition to the 3.6 meter wide passage to the market hall, it contains a 1.6 meter wide passage for pedestrians on the left and right. Granite fairways in the passage, as in the adjacent courtyard, directed the car traffic. Between the fairways it was paved with iron pavers, the rest of the courtyard area was paved . Iron posts with chains stretched between them separated the car traffic from the pedestrian traffic. The pillars, belts and cross ribs of the 6.0 meter high passage made with light red clinker bricks and shaped stones contrast with the light yellow vaulted vaults and wall surfaces, enlivened by strips of inlaid blue-green glazed bricks. In the dark, two 9-  amp arc lamps lit the passage if necessary.

The business premises of the Städtische Sparkasse on the ground floor of the left half of the house and the associated side wing were oriented towards the passage and the adjacent courtyard. The customers entered the branch through a portal in the passage. The rooms, which were about one meter above street level, included the accounting officer’s room (referred to as the Rendant in the plan ) with a vault behind it , the hall for the public, a meeting room for the board of trustees and toilets . A spiral staircase in the meeting room led to the registry of the savings bank on the upper floor of the side wing.

On the first floor of the right wing, just a few centimeters above street level, there was a large and a small shop as well as the main stairwell of the house. The right wing was originally planned as an apartment for the tenant of the larger shop. The ground floor on the level of the market hall, however, had to be assigned to the meat show office as a planning change and the cellar rooms below were used by the market police to store confiscated meat and other objectionable market goods. Only the 2.5 meter high mezzanine floor above could be rented out as planned.

On the three upper floors of the front building, the city of Berlin rented two large apartments, each comprising the front building and a side wing, and a small apartment in the eastern side wing.

The late classical facade on Zimmerstrasse

The late classical facade is in the tradition of the Schinkel School . Blankenstein used a combination of sandstone and brick in the form of clinker bricks, shaped stones and terracottas in light yellow and light red shades. The 10.2-meter-wide, three-axis central projection juxtaposes the two three-axis side facades slightly in front of the building line by 25 centimeters and emphasizes the access to the market hall. The approximately 5.8 meter high arched portal of the wide passage in the central axis is flanked on the left and right by the two 3.3 meter high arched portals of the pedestrian passages. These openings could be closed with ornate wrought iron grilles.

Above the apex of the central arch, an inscription, Markthalle III, which is no longer present, named the purpose of the building. Two square-framed sandstone medallions above the pedestrian passages illustrate the function of the market hall. The right medallion slung two snakes is Caduceus as a general symbol of Trade and Industry. The rod is also the axis of a beam scale , which refers to the weighing process that takes place innumerable times a day in the market hall. Interpreted as the Libra of Justice , it symbolizes the fair , state-controlled weighing in the market halls. Fruit in the form of grapes, apples and pears on the scales show the goods offered in the market hall. In the left medallion is the winged helmet of Hermes, a second general symbol for trade and economy. The trident of Poseidon , crossed with a butcher's ax , fish and crabs hanging from the teeth of the trident, the flowers and the bunch of vegetables hanging from the butcher's ax tell of the other market offers and their origins.

Three large round arches lined up next to each other form the ground floor in the left and right wing. The economical, sculptural jewelry is limited to the capitals and rosettes between the arches. The entire ground floor is covered with Warthauer sandstone above the 30 centimeter high granite base .

The decorated with rosettes Terrakottarahmungen the segmental arch windows on the first and second floors and their with a Kyma profiled Verdachungen , are in the same bright yellow hue as the entire facade. The meander frieze , which runs through the lintel height of the segmental arched windows on both floors, stands out with its bright red and emphasizes the horizontal. The large terracotta panels between the windows of the central risalit on the first and second floors show tendril and leaf patterns in Renaissance shapes . On the first floor, female figures hold plaques with the dates 1884 and 1886 - the beginning and end of the construction period.

A light red leaf and rosette frieze under the window ledge separates the second and third floors. In the place of the segmental arched windows on the lower floors, there are two coupled, smaller segmented arched windows in the side wings. At the corners of the central risalit, the coat of arms of Berlin with the Berlin bear and on the right the coat of arms of Prussia with the eagle are emblazoned as emblem . Attached terracotta panels with tendrils and leaf ornaments between the windows of the central risalite and at the ends of the wings combine the windows on the third floor into a band. A cantilevered round arch frieze supported by consoles leads over to the eaves, which, after a tooth cut, closes the facade with the acanthus- decorated guttering and the antefixes in the form of palmettes at the top. The very flat sloping gable roof cannot be seen from the street.

The front building at Mauerstraße 82

The facade at Mauerstrasse 82

The narrow width of 5.13 meters on Mauerstraße was just enough for the passage to be created. The 3.6 meter wide and 6.0 meter high passage, covered at the beginning and at the end with barrel vaults and in between with Gothic -looking ribbed vaults , dominated the ground floor of the two-storey building. The color scheme with light yellow and light red clinker bricks and shaped stones as well as blue-green glazed bricks corresponded to the passage on Zimmerstrasse. Granite fairways were used to direct the carriage traffic . The iron and glass construction of the 3.6 meter wide and 3.4 meter high double-leaf gate was embedded in the rear arched opening of the front building. So that the large gate did not have to be kept open all the time the market was open, there was an additional 1.0 meter wide and 2.18 meter high door for pedestrians in each gate wing.

The remaining area of ​​the ground floor of the front building was shared by two narrow stalls, which could be closed by corrugated iron blinds, and the staircase that led to the small official apartment on the upper floor. In the rear part of the property, the passageway, continued as a covered hall, took up about half of the property. A pent roof sloping towards the center line of the property covered the passage. Numerous recessed skylights illuminated the passage during the day. In the dark, the passage could be illuminated by two arc lamps of nine amperes each. On the other half, after the front building, there was a light and service courtyard, followed by three rooms for the administration of the market hall, accessible from the passage. On the market hall wall and only accessible from the market hall, there were other toilets. A pent roof with skylights, sloping towards the passage, covered these buildings.

The circular portal, lockable two-winged by a richly decorated iron gate, embossed with bright red and bright yellow bricks , shaped bricks and terracotta veneered facade. Laurel wreaths interwoven with ribbons adorned the gussets of the round arch decorated with bundled round bars. Below the cornice on the upper floor, a terracotta panel with the inscription Markthalle III announced the purpose of the building. Three coupled arched windows, separated by columns, illuminated the only room in the official residence facing the street. Four light yellow clinker layers alternated with a light red layer in this area. A frieze made of terracotta panels was followed by the protruding cornice supported by consoles with a round arch frieze.

The attic crowned with a segmented arch and two palmettes referred to the client in the central axis on a terracotta panel with the coat of arms of Berlin. Two more panels showed the beginning and end of the construction period on the right with 1884 and on the left with 1885. The incorrect indication of 1885 instead of 1886 could be related to the conflict between the magistrate and the police headquarters, which led to a delay of six months. Presumably the terracottas had already been made and a subsequent change was too expensive. Another explanation is that only the plans were not updated.

The market hall

The actual market hall appeared on the outside only at the northern end of the courtyard of the Sparkasse building as a shield wall of the central nave through an 8.5 meter wide and 11.6 meter high arched portal. An iron and glass construction closed the hall from the courtyard. A two-winged gate 4.0 meters wide and 4.5 meters high, entitled Market Hall III , was set in the central axis . This gate was only open in the early hours of the morning before the market opened and then again after the market opened. The customers entered the hall through the two 2 meter wide and 2.8 meter high entrance doors on the side, which were labeled with Entrance and Exit . To avoid train vestibules were retrofitted for these doors. The electric clock, with a dial visible from inside and outside in the middle of the arch, had a counterpart on the opposite inner wall of the hall. The façade made of light yellow and light red bricks was decorated with a few shaped stones and two rosettes next to the round arch. An acroter on the gable once again showed the coat of arms of Berlin as a national emblem.

Surrounded by the southern wall of the hall and the side wings of the front building on Zimmerstrasse, there were two 6.6 meter wide atriums at basement level, which also served to ventilate the basement. Two low, single-storey buildings on the western and eastern property line with toilets for women and men followed.

In continuation of the central axis of the savings bank building was the nine meters wide and around eleven meters high main nave of the market hall, which towered over the lower aisles. At the end of the hall, the central nave at the intersection with the passage from Mauerstraße was crowned by a lantern in the form of an irregular octagon with a diameter of 16.6 meters. This octagonal room with its tent roof towered over the main nave of the market hall and with its surrounding window wall of around 3 meters in height, it provided enough light in the rear part of the market hall. Ten 6 meter high cast iron columns at a distance of 6 meters supported the central nave on both sides. Square iron posts, 4.5 meters high, were placed on top of them, between which the wrought iron arched trusses of the central nave were clamped, the upper chords of which followed the flat incline of the gable roof, while the lower chords were designed as round arches. The stiffening rings with a diameter of 1.0 meter in the arched spandrels were used for the static stiffening of this girder construction. I-profile irons attached as purlins between these arched girders supported the wooden rafters of the gable roof . At the height of the arched trusses, the central nave appeared as a 2.4 meter high window wall. Tilting sashes, perforated metal sheets and glass blinds were used for ventilation.

The central nave was accompanied by three 7.6 meter wide aisles on the left and right. 6 meter high cast iron columns and 1.84 meter long tongue walls on the outer walls carried the shed roofs , which were favorable for lighting and ventilation . Blankenstein designed the outer walls inside the market hall with the light yellow and light red clinker bricks and glazed bricks already familiar from the passages. Light red facing bricks followed in the lower quarter of the wall above a 31 centimeter high granite plinth. The upper, light yellow paneled wall surfaces were separated by a cornice made of light red shaped stones. The central nave with the passage was paved with six centimeter thick iron clinkers, the aisles and islands with the market stalls with non-slip, ribbed Sinzinger tiles.

In the dark, four powerful arc lamps of 15 amperes at a distance of 18 meters in the main nave and 22 weaker arc lamps of 6 amperes in the side aisles illuminated  the market hall. The electricity required for this was supplied by a gas- powered electric generator with an output of 30  hp in the basement. After the Berliner Elektrizitätswerke had built their Central Station II directly on the northern border of the plot in 1889, at Mauerstraße 80, the market hall was connected to the public electricity network.

At the time of opening, the market hall had a usable floor space of 3233 square meters with 353 fixed stands. Seven stalls sold sea fish and crabs, and eleven stalls offered live river fish in a total of 32 fresh water basins. Housewives were able to stock up on butter, cheese and vegetables at 173 stalls, 24 stalls supplied flour, bread and pre-meals (starters) and an impressive 138 stalls sold meat and game. 170 square meters of the hall was intended for the trade in wood without a fixed stand and right next to it, birds and flowers could also be used to cover needs that were not directly related to daily needs. In the extensive cellars of the market hall, which stretched under the whole hall, there was sufficient space for storing goods that were not immediately sold. Three stairs on the walls, two stairs inside the hall and a lift connected the basement with the hall.

On the 16.33 meter deep strip between the northern wall of the hall and the property boundary, a restaurant with its own farmyard was set up. The two-storey, L-shaped building contained the kitchen, the dining area and the own toilet facilities on the ground floor. The lounge for the market hall workers, accessible from the hall, was part of the hall's infrastructure. A light pit along the building let some light into the basement of the market hall. The landlord lived upstairs and his employees' bedrooms were in the attic. The scullery of the restaurant in a single-storey, iron framework extension, adjoined the farm yard. At the request of the building police, the farm yard was given its own passage, which was laid along the eastern boundary of the property. Through this passage and a connecting passage in the octagonal room at the end of the market hall, which can be separated by a lattice wall, the guests reached the restaurant via a side entrance next to the toilets when the market hall was closed.

Conversion to the Berlin concert hall Clou

Interior view of the Clou concert hall around 1911

After the construction of the market hall, Friedrichstadt developed from a residential to a business district through the demolition of residential buildings and new commercial buildings. Due to the constant decline in the resident population, the operation of Markthalle III became unprofitable and it was closed in 1910. The city of Berlin leased the market hall from April 1, 1910, initially for 15 years to the catering company Hoffmann & Retschlag . The front building on Zimmerstrasse remained in urban use by the Sparkasse branch.

In 1910, the architect Johannes Kraaz adapted the market hall to the needs of the entertainment venue. He transformed the former stalls for fish and meat along the longitudinal walls, separated by tongue walls, into arched niches with coffered ceilings , the round cast iron columns disappeared behind a rectangular casing. A covered ceiling in the aisles hid the shed roofs. The former main nave was transformed into a wide central promenade, which ended in the direction of Mauerstrasse in a large domed room under the former octagonal lantern of the market hall. In its center, a fountain with an illuminated fountain splashed as an attraction. The dais above the entrances to Zimmerstrasse, with its 140 square meters, also offered space for the largest orchestras. With an area of ​​4,000 square meters and seating for 3,000, the result was Berlin's largest entertainment venue at the time. The wine store of the Hoffmann & Retschlag wine wholesaler moved into the extensive cellars of the former market hall.

The painter Albert Maennchen (1873–1935), a Berlin specialist for decorative and monumental painting who made a name for himself in the previous years, played a key role in the transformation into a concert hall . a. in the field of the artistic design of exhibition architecture. Maennchen designed a figurative image program for the dome of the Clou, consisting of a triptych with Cupid as the world regent and six image fields with individual standing figures. The wall, pillar and ceiling surfaces of the ships and niches, on the other hand, were painted in a finely coordinated color scheme with ornamental fields, colored areas and linear ornaments. During the opening phase of the Konzerthaus, Maennchen also designed the advertising graphics for the Konzerthaus, including the Clou logo with the bear-riding muse , which was used on advertising cards and stamps, as a poster motif and in press advertising. The Clou concert hall was the largest uniformly designed interior of the late Art Nouveau. During the first major change to the Clou in 1913, Maennchen replaced the triptych with a large painting with a group of figures walking through the great outdoors.

A Berlin travel guide wrote in 1912:

“Clou, a huge bar, a former market hall. Entrances Mauerstr. 82 and Zimmerstr. 90/91. A restaurant in which For the 'Promenade Concert' (free entry) the petty-bourgeois Berlin gathered with knitted stockings and crochet. In the large central aisle is the parade of the young world. In the evening there was also a lot of family audience, but more mixed. A military band usually plays until 7 o'clock in the afternoon, a costume band such as Tegernsee, Gypsies, etc. in the evening. Admission after 7 o'clock 50 pfennigs. Beer and food at cheap prices. "

- Berlin for connoisseurs

The function of the house is only partially described with the Berliner Konzerthaus . In addition to concerts, political events were also held. On May 1, 1927, Adolf Hitler gave his first speech in Berlin at a general meeting of the NSDAP . The meeting was not open to the public because in 1925 Prussia banned him from speaking .

Reconstruction and sale of the property in the late 1930s

Another renovation in 1934 adapted the restaurant to the changing tastes of the time. During the redesign in a functional, modern style, the truss structures of the market hall, which were still visible in the central nave, disappeared under the ceiling that was suspended at the same height as the side aisles. Like the walls, the new, all-encased columns were painted with horizontal stripes and lit indirectly, so that the ceiling with the recessed colored glass skylights almost seemed to float. The program changed with the renovation. The focus was now on teas and balls for which a 400 m² dance floor was available. Often an artistic supporting program accompanied the events with titles such as Revue der Weine or An Evening on the Rhine .

At the end of the 1930s, the city of Berlin divided the property and sold the former market hall and the front building on Mauerstraße to the previous tenant Hoffmann & Retschlag. The front building on Zimmerstrasse came into the possession of the central publishing house of the NSDAP , Franz Eher Nachhaben GmbH . The publishing house set up its Berlin branch here and in the neighboring houses at Zimmerstrasse 87-89, which were also acquired. The editors moved into the former building of the savings bank and, along with other propaganda magazines for the party, such as Das Schwarze Korps or The Attack, were responsible for the Berlin edition of the Völkischer Beobachter . The printing machines were in the neighboring houses at Zimmerstrasse 87-89. After the war, the SED party organ Neues Deutschland was printed on them.

The concert hall, which had already been closed due to the war, served in 1943 as one of the assembly camps for the so-called " factory action ", the arrest of the last Jews who had been spared from deportation until February 27, 1943 and who were still forcibly employed in Berlin armaments factories. There were isolated attacks.

Post-war and present

The memorial plaque on the front building

Towards the end of the Second World War, aircraft bombs destroyed the facilities of the former market hall, except for the front building and its western side wing on Zimmerstrasse. After the Berlin Wall was built in 1961, right in front of the house, it was in the inaccessible border district until 1989. Machines were produced in the building until 1992. After a renovation, which was completed in mid-2006, the street and rear façades as well as the passage appear in their new splendor and a memorial plaque installed in 2001 informs about the history of the house. Art galleries are mainly rented in the building today. From January 2011 to November 2014, the permanent exhibition "STASI" on the history of the GDR state security was located on the ground floor . A Live Escape Game has been on the premises since October 2015.
