The Ahrensburg tunnel valley has numerous stations of late Paleolithic reindeer hunters. Today the Lübeck – Hamburg railway follows the flat valley floor . The finds around the valley are so important that prehistorians generally speak of the " Ahrensburg stage ". Before Indo-European settlers, who, according to a controversial theory by Theo Vennemann (see Vaskonische Hypothesis ), owned a language related to Basque , called this place Arn for valley, from which the current place name can be derived.

middle Ages

The history of the city goes back to the 13th century, when the Counts of Schauenburg founded the village of Woldenhorn (which later became the city of Ahrensburg) and the neighboring villages of Ahrensfelde, Meilsdorf and Beimoor. Woldenhorn was first mentioned in a document in 1314. The villages came to the Cistercian monastery Reinfeld in 1327 , and Woldenhorn was the seat of the monastery bailiff until the middle of the 16th century.

Around the middle of the 11th century, the "Arx Arnsburga", also known as Arnesvelde Castle , was built, the dimensions of which can still be clearly seen through the outer moats in the Hagen Forest in the south of the city. The coat of arms of the city shows the Arnesvelde castle in the upper coat of arms. Bailiffs residing at the castle are attested in 1295 and 1304. In 1326, the Schauenburg count Johann III. the seat of his governor to Trittau and gave up the castle.

The Ahrensburg Castle is said to have been built from the stones of the castle .

Modern times

With the secularization due to the Reformation , the King of Denmark became the owner of the area. He rewarded his general Daniel Rantzau in 1567 with rule over these villages. His brother and heir Peter Rantzau built the Renaissance mansion in the form of a moated castle and the castle church, today the city's landmark. The incorporation of “Gottesbuden” (apartments for old and destitute people) into the church was exemplary.

The " Gut Ahrensburg " belonged to the so-called noble estates , which had considerable self-administration and independence. For the peasants, however, the rule of the Rantzaus meant serfdom.

The Rantzaus estate was heavily indebted in the middle of the 18th century and was acquired in 1759 by the merchant Heinrich Carl von Schimmelmann , who redesigned the castle and farming village in the Baroque style and whose plans the city today is based on. Schimmelmann gained wealth through the arms, alcohol and slave trade, especially in the Atlantic triangle trade .

On June 7, 1867, the previous Gutsdorf Woldenhorn became an independent Prussian rural community and was renamed Ahrensburg by resolution of the community assembly . It belonged to the "Amt Ahrensburg" of the same name, from which it left in 1912 as a municipality that was then free of charge.

With the construction of the railway line from Hamburg to Lübeck in 1865, Ahrensburg became a popular excursion destination in the Hamburg area and the population increased. In 1910 there were already 2750 inhabitants. Incorporation in 1928 led to an area enlargement by 500 ha.

Until the early 1930s there was a small Jewish community in Ahrensburg , whose synagogue was set on fire on November 9, 1938, during the Night of the Reichspogrom .

The settlements “Daheim / Heimgarten” (partly in the area of ​​today's Ammersbek municipality ) and “Am Hagen” (originally: “ Franz Seldte settlement”) were built on the area of ​​the former estate from 1933 . The onslaught of settlers from the Hamburg area led to the emergence of today's relaxed settlement structure.

At the beginning of the Second World War , only 8,270 people lived in Ahrensburg. At the end of the war, the population of Ahrensburg rose to over 18,000 due to the influx of bombed-out Hamburgers and numerous refugees from eastern Germany. Germany was eventually occupied gradually. On May 3, 1945, British troops also advanced towards Ahrensburg. The mayor, Gramm, is said to have driven in a car towards Schmalenbeck that day, without having had orders or permission, to signal to the British that Ahrensburg would surrender without a fight. At the same time, the local group leader is said to have walked around drunk and shouted slogans to hold out. Nevertheless, British tanks of the 15th Scottish Division moved into Ahrensburg on the same day. On May 4th, Hans-Georg von Friedeburg signed the surrender of all German troops in north-west Germany, the Netherlands and Denmark near Lüneburg on behalf of the last Reich President Karl Dönitz , who had previously left the last Reich government in Flensburg - Mürwik . The unconditional surrender of the Wehrmacht followed on May 8, 1945. In Ahrensburg, the British occupiers temporarily set up a headquarters in the castle.

When Ahrensburg was granted town charter on January 18, 1949 , it had 17,775 inhabitants - around half of them refugees and displaced persons from the former German eastern regions.

In the following decades, the city's infrastructure was greatly expanded. At the same time, numerous companies settled on the outskirts, which made Ahrensburg a well-known business location in Schleswig-Holstein .

The company model developed by Joh. Friedrich Behrens , a company for the manufacture of pneumatic nailers, was named after the city as the Ahrensburg model .



Ahrensfelde was first mentioned in a document in 1195. It consisted of the castle in the Hagen forest and the surrounding village. In 1320 the castle was badly damaged during acts of war. In 1327 the place came under the rule of the Reinfeld Monastery , which subordinated it to the Bailiwick of Woldenhorn . From 1567 on, Ahrensfelde belonged to the noble estate of Ahrensburg for three centuries . The serfdom was abolished in 1797 after it in the first half of the 18th century it conflicts with landlord Detlev Rantzau had given. In 1867 Ahrensfelde became a Prussian rural community and belonged to the Siek district until 1948 , then to the Ahrensburg-Land office until 1951 . From 1951 until it was incorporated into Ahrensburg in 1974, the village belonged to the Siek district . When it was incorporated, Ahrensfelde had 475 inhabitants.

Beimoor / industrial area north

Beimoor was first mentioned in a document in 1300 as a scattered settlement. Originally belonging to the Reinfeld monastery , the small village became part of the noble estate of Ahrensburg in 1567 . The name probably means berry bog . In the middle of the 19th century there was a farm on the site of the estate in addition to some leaseholds that had been created in 1788 after serfdom was abolished. In 1889, Beimoor, now a Prussian rural community, came to the Ahrensburg district , until the new large community of Ahrensburg was incorporated in 1928. At that time it had 47 inhabitants.


The West U-Bahn station and the West industrial park are located in this district. Part of the Bredenbeker pond belongs to this district. The church and city cemeteries are also located here. In addition, there is the district of Wulfsdorf on the border with Hamburg. The village project "Allmende" with well over 300 residents was created here in 2003.

Garden wood

The youngest district in the north of the city is only separated from the northern industrial area by the Lübeck – Hamburg railway line . Since the end of 2010 it has had its own train stop. In addition to the Gartenholz development area, which was created in the late 1970s, there is the older Kremerberg settlement on the northern outskirts.


The Erlenhof residential area is a district that is under construction. The northern part, for example (Erlenhof-Nord), should contain a total of 600 residential units. It has its own day-care center , maybe its own school should also be built.


The Hagen was originally a forest area that bordered the Stellmoor-Ahrensburg tunnel valley . It has always belonged to the Vogtei Woldenhorn and from 1567 to the noble estate of Ahrensburg. The landlord in 1868 closed the area to the general public. After the estate district was dissolved in 1928, the owners sold large parts of the Hagener Land as building land. There the German Settlers Association established the Franz Seldte settlement (today: "Siedlung am Hagen") around 1935 . The "Waldgut Hagen settlement" was built on other areas in the 1930s. The undeveloped part of Hagens has been a nature reserve since 1982. After the opening of the Ahrensburg Ost underground station, the Hagen became a destination for Hamburgers to visit.


In 1928 the municipalities of Wulfsdorf, Beimoor (first mentioned in 1300), Kremerberg and parts of the disbanded manor district were incorporated. In 1932 the rest of the disbanded manor was added. Ahrensfelde was incorporated on February 1, 1974.

From 1823 to 1899, Ahrensburg was the seat of the Stormarn provost of the Evangelical Lutheran Church . Today - besides a Baptist congregation , an Elim congregation and a Free Evangelical congregation  - an Evangelical Lutheran , a New Apostolic and a Roman Catholic congregation as well as the Ulu Camii ( Great Mosque ) mosque determine the religious life of the city.

Until the early 1930s there was a small Jewish community in Ahrensburg , whose synagogue was set on fire on November 9, 1938, during the Night of the Reichspogrom . Today you can still visit the Jewish cemetery (laid out in 1822) on the outskirts (Ahrensburg-West) near the golf course as a remnant from that time. Since 2003 there is again a small Jewish community that advocates progressive Judaism (non-orthodox faiths).

City Council

The election to the city council on May 6, 2018 led to the results shown in the diagrams on the right.

The turnout was 49.9%. 13 of the 16 direct mandates went to the CDU. In order to correctly reflect the voting ratio, the city council was enlarged to 40 seats.


coat of arms

The first documented suggestions for an own coat of arms go back to 1927. After several drafts were discarded for heraldic reasons, on February 28, 1938, the approval of an Ahrensburg municipal coat of arms was given by the President of the Province of Schleswig-Holstein. However, the first coat of arms did not get beyond the stage of a description.

As part of a revision of the main statute in 1962, a review of the description was arranged by the Schleswig-Holstein State Archives. There were considerable doubts about the description, especially the coloring. After more than 14 years, the Interior Minister of the State of Schleswig-Holstein finally approved today's city arms on November 1, 1976.

Historical reason:

“The city's coat of arms is linked to the historical facts associated with the name 'Ahrensburg' :

The reindeer antlers on the cult stake in the lower half of the coat of arms, a find from the nearby prehistoric site Stellmoor , reminds of the settlement activity of Paleolithic reindeer hunters in the Ahrensburg area, the traces of which have become known in prehistoric research as ' Ahrensburg culture ' .

The castle in the upper half of the coat of arms stands as a symbol for the castle complexes to which the city owes its name: Arnesvelde , also known as Arnsburga , was first mentioned in 1306 and was built during the colonization of Stormarn, probably linked to the old Saxon refuge , and afterwards Transfer of the castle complex to the noble Rantzau family and abandonment of the old castle square - Ahrensburg moated castle built around 1595 .

The town's affiliation with Holstein is indicated in the dominant colors of silver and red. "

Blazon :

“In silver, a red castle towered over on both sides by low, black-roofed towers with a protruding, black-roofed gate tower and an open gate. Underneath on a growing red pole is the black stylized skull and the black stylized shovels of a reindeer. "

The castle is reminiscent of the "Arx Arnsburga" and the reindeer shovels refer to the excavations by Alfred Rust in the nearby Stellmoor.

City flag


Blazon : "In a white cloth, bordered by a wide red stripe at the top and bottom, the red castle and underneath the black, stylized reindeer antlers (with skull) of the city coat of arms, slightly shifted towards the pole."

Town twinning

Ahrensburg maintains city ​​partnerships with:

Culture and sights


In addition to the Ahrensburg Castle , the neighboring castle mill on the Mühlenredder and the castle church with the holy booths , the Marstall and the House of Nature in the Wulfsdorf district should also be mentioned.

Next to the castle is one of the oldest buildings in the city, the former wash house of the Count Schimmelmann family, the Bagatelle. This house was renovated over many years by the “Ahrensburger Bürgererverein” and saved from total decay.

On the Rondeel, a square in the center of the city, there is a work of art by the Kiel artist Martin Wolke . The “mussel runner” has been causing heated discussions in Ahrensburg since it was established in 2005 and has become known beyond the city limits.

Green spaces and recreation

In summer, the Bredenbeker Teich natural pool (420,000 m² lake, small island) is a popular destination.

In the south there are several nature reserves: Ahrensfelder Teich, Stellmoor-Ahrensburger Tunneltal, the former military training area Höltigbaum and the Hagen forest.


There are various sports clubs, such as B. the Ahrensburger TSV (whose women's team played in the table tennis Bundesliga in the 1988/1989 season), SSC Hagen Ahrensburg , tennis and hockey club Ahrensburg, golf club Hamburg-Ahrensburg. The oldest association in town is the Ahrensburger Bürgerverein v. 1874.

All clubs for young people are organized in an umbrella organization, the Stadtjugendring.

In addition, there are numerous riding stables in Ahrensburg, so there are six riding facilities in the Ahrensfelde district. Five riding clubs meet here.

In the “Alte Meierei” car park, the 29 participating e-cars started every minute on November 17, 2018 from around 7 a.m. for the very first e-cannonball .

Economy and Infrastructure


Public facilities

The Bruno-Bröker-Haus is located in Ahrensburg, only called Bruno or BBH by the young people. This is a leisure center and meeting place for children and young people.

The G-Haus (Gartenholz community center) is an urban youth facility (district center). Billiards, table tennis, table football, darts, but also board and card games are available. Excursions to the Heidepark, Snowdome, the kart track, the cinema or the swimming pool are part of the program, such as handicrafts, cooking together, barbecuing, volleyball, football and other group activities. On Saturdays, the inline hockey group trains in the sports hall. A holiday trip is carried out once a year (e.g. skiing to Austria, active holiday in Bavaria). The facility can also be used to meet friends, to chat or to discuss problems with the teachers who work there. They offer visitors support in coping with their everyday problems. This also applies to the parents.

Ahrensburg has a leisure and indoor pool, the Badlantic. In addition to being used as a fun pool, it also serves as a training facility for various sports clubs.

Federal highway 75 ran through the city until the beginning of 2015 , and from 1990 bypassed the inner city center. In January 2015 it was downgraded to L 82. The location of the city on the A 1 motorway (extended bird flight line ), at which the junction of the same name is located southeast of the urban area, is decisive for traffic .

Ahrensburg is connected to the supra-regional railway network via the Lübeck – Hamburg railway line (in regional traffic: RE 80 and RB 81) . In addition to the Ahrensburg train station, there has been a second stop on this route since November 2009 in the northern part of Ahrensburg's Gartenholz district. Commissioning was delayed due to improvements to comply with EU regulations (for the 2010/2011 timetable change on December 12, 2010). Since then it has been served by regional trains on the RB 81 line.

The construction of an S4 S-Bahn line has been under discussion for a long time .

Ahrensburg has been linked to Hamburg by the Walddörferbahn (now part of the U1 underground line ) since November 1921 . In 1949, this made Ahrensburg the fourth German city with a subway connection. The underground stations Ahrensburg West (until 1952 "Ahrensburg") and Ahrensburg East (until 1952 "Hopfenbach") are located in the city of Ahrensburg . For a city of this size, Ahrensburg has a comparatively dense city ​​bus line network with five inner-city and six regional bus routes in daytime traffic and several bus routes in late and night traffic, which is mainly operated by the transport company Verkehrsbetriebe Hamburg-Holstein (VHH). All public transport (regional transport, subway and buses) are integrated into the network of the Hamburger Verkehrsverbund (HVV).
