Iburg Castle and Monastery in Bad Iburg are among the historically significant buildings in the Osnabrück district in Lower Saxony .

The Iburg was built in 1070 on a hill as a castle with a wooden chapel, the Benedictine monastery in it was founded in 1080. From the 11th to the end of the 17th century, the bishops of Osnabrück resided in the double complex of castle and monastery. The knight's hall from the 17th century is noteworthy in terms of art history because of its ceiling painting in a pseudo-perspective architecture. Iburg is the oldest knight's castle and, next to Holter Castle, the only mountain castle in the diocese .

Building history

The knight's hall of the castle dates from the time of Franz Wilhelm von Wartenberg
Monastery wing by Johann Conrad Schlaun
Siege 1553

The first building on the site of today's facility was a Saxon refugee castle . It was located near a pass road (today Bundesstrasse 51 ) that led through the foothills of the Teutoburg Forest . Bishop Benno I (1052-1067) and Bishop Benno II (1068-1088) had the residence of the Diocese of Osnabrück built on the remains of the fortifications, which at that time formed ring walls . Like all knight seats in the country, it was also a moated castle.

Bishop Benno II brought twelve Benedictine monks from Mainz to Iburg in 1080 . This year is seen as the year the monastery was founded, but a wooden chapel had already stood on the castle hill in 1070. The building material for the monastery came from the so-called Bennost quarry on Dörenberg . Under Bishop Konrad IV von Rietberg (1492 to 1508) the octagonal keep was built on the remains of a previous building from the 11th century. The tower appears in the coat of arms of the district of Osnabrück and is called "Bennoturm" by the population, although it was only built after the eponym died. The tower in which Benno II lived stood on the western slope in front of the curtain wall ; its remains were discovered in 1983 during construction work. At the beginning of the 17th century the castle and monastery were redesigned into a richly structured palace complex at the instigation of Prince Bishop Philipp Sigismund von Braunschweig-Wolfenbüttel (1591 to 1623).

In 1553 the generals Christoph von Wrisberg and Dietrich von Quitzow besieged the Iburg when they moved with Philipp Magnus von Braunschweig-Lüneburg (1527–1553) against the bishopric of Osnabrück . They wanted to take Bishop Franz von Waldeck into captivity in the castle. Iburg was sacked and the monastery became a fire treasure of 4000 Taler forced.

During the Thirty Years' War the palace and monastery suffered severe damage from looting in 1621, 1623 and 1633. The occupations, by the Dutch in 1632 and especially by the Swedes in 1634–50, also caused damage. The Swedes drove out the monks, who did not return until 1645. 1668 was in the castle Sophia Charlotte of Hanover born, in 1701 as the wife of Frederick I first queen in Prussia was.

Bishop Franz Wilhelm von Wartenberg , who had fled the Swedes, returned in 1650 and had entire wings of the building completely renovated. The equipment of the knight's hall dates from 1656/57. The architect responsible was Johannes Crafft, who came from southern Germany.

The work started by the Catholic Bishop Franz Wilhelm von Wartenberg was completed around 1674 by his successor Ernst August I , the first Lutheran bishop from the House of Braunschweig-Lüneburg. He had the Lutheran castle church built (1664).

Abbot Adolph Hane (1706–1768) had a new monastery built on the castle hill by the Westphalian baroque master builder Johann Conrad Schlaun .

The design for the entrance gate to the palace complex on the so-called Klotzbahn comes from the spa-Braunschweig-Lüneburg master builder Franz Schädler (1733–1796) . It was made in 1781 by master blacksmith Johann Georg Reinhard.

Surname

The origin of the name Iburg cannot be clearly proven. Franz Jostes derives the name from I = water (corresponding to the Dutch Y for water).

Prince-Bishop's family life

Sophie Charlotte , the first queen in Prussia, was born in 1668 in Iburg Castle
Her mother Sophie von der Pfalz described the castle as a "very nice house"

Sophie von der Pfalz , who lived there from 1662 to 1673 with her husband, Prince-Bishop Ernst August I of Braunschweig-Lüneburg , wrote about the Iburger Schloss after arriving to her brother Karl Ludwig von der Pfalz : I am here three days ago arrived and am in a very pretty house, which pleased me very much when it arrived; everything that catches the eye on it appears splendid: equipment, furniture, livery, guards, halberds. In 1663 she described life in the Iburg: We play skittles, pull ducks, hold ring races, play trictrac, want to go to Italy every year, but things are going quite well for a little bishop who can live in peace. Three years later, the little bishop could not live in peace. In 1666, Ernst August I and Sophie von der Pfalz temporarily moved to a courtyard in Osnabrück Neustadt, further away from Münster, due to political tensions with the neighboring Catholic Bishop of Münster, Christoph Bernhard Graf von Galen . After returning to Iburg, Sophie wrote on June 2nd, relieved: We live here in the most pleasant solitude in the world. We enjoy all the joys of country life and reject all who want to wait for us at the table; we see no one except our society.

In 1668 the only daughter of the prince-bishop couple , Sophie Charlotte , was born in Iburg Castle. As the wife of Frederick I, she became the first queen in Prussia.

Over the years, the prince-bishop's premises were not enough. He also wanted to limit the independence of the city of Osnabrück and therefore decided to build a new building there. In 1673 the prince-bishop's family moved into Osnabrück Castle . This ended the era of the bishops of Osnabrück in Iburg Castle.

Bishops of Osnabrück in Iburg Castle

The Osnabrück bishops resided in Iburg from 1086 to the end of the 17th century .

Ernst August I of Hanover had Osnabrück Castle built. This ended the story of the bishops of Osnabrück in Iburg Castle.

Benedictine monastery

The monastery, founded in 1080, existed until the beginning of the 19th century. The third abbot of the monastery was Benno II. Norbert von Iburg , who wrote the biography of the monastery founder while he was still alive . From 1666 to 1706 Maurus Rost was the 41st abbot of the monastery. The convent buildings preserved today go back to the new building in the 1750s under Abbot Adolph Hane. The Westphalian architect Johann Conrad Schlaun was commissioned with the construction plans , but his design may have been changed at the client's request. The high garden terrace in front of the eastern façade can serve as an indication of this. The main entrance was - contrary to the baroque understanding of the axis - relocated to the north side. Inside, which is now largely used by the Bad Iburg District Court, stucco decorations from the time of construction have been preserved in numerous rooms (Joseph Geitner). They essentially follow the usual monastic and theological decoration program of the time with scenes from the Bible, allegories, emblems and plant-animal decorations. On February 13, 1803, the monastery was closed after a good 700 years of existence. The Reichsdeputationshauptschluss dated February 25, 1803 and was officially confirmed on April 27, 1803, but the secularization in many areas took place before the legal validity. Iburg was the first monastery in the Principality of Osnabrück to be abolished. At that time the convention still had 22 members. Servants and domestics had already been dismissed on February 9 and 10, 1803. The monastery was completely emptied, the inventory was sold except for the church equipment and library, whose holdings were estimated at 4,000 books. The library became state property. In Napoleonic times it remained unused in Iburg, in 1816 it was brought to Osnabrück Castle. In 1817 the Carolinum grammar school in Osnabrück took over the stock. Most of it was destroyed in the bombing of Osnabrück in September 1944; the remains are in the Osnabrück city library.

Baptist in the keep

Bennoturm

In 1534 members of the Anabaptist Empire of Munster were held prisoner in the keep , the so-called Bennoturm . The Baptist Johann Bockelson, known as Jan van Leiden , sent 27 preachers as apostles from Münster in October 1534 , including six to Osnabrück. The city council arrested all six on October 15. They were the two Dutchmen Dionysius Vinne from Diest and Peter Kueper from Sneek , the schoolmaster Heinrich Graes from Borken , the butcher Johann Boentorp from Münster, Johann Scheffer from Freckenhorst and Paul Schwering. They were brought to Iburg, where they arrived on October 18 or 19, 1534. The prisoners were taken to the Benno Tower and interrogated and tortured in the following days. One of them did not survive the torment. The rest of them were sentenced to death for rioting and beheaded - with the exception of the former schoolmaster Heinrich Graes. He had been separated from the other prisoners after he had indicated that he could make important statements. So he managed to be brought before Bishop Franz von Waldeck . He believed his assurances that he could prepare an attack against the city of Munster or spy on the plans of the Anabaptists. The bishop released him on a guarantee of 1100 guilders. Graes was welcomed with joy in Munster. When Jan van Leiden sent him to Wesel and Deventer, he separated from his companions and returned to Iburg at the turn of the year 1534/35. There he revealed the plans of the Anabaptists. He was sent again to investigate the intentions of the Anabaptists in Wesel. After his return, the bishop rewarded him and dismissed him for having rendered important services to the “entire German nation”.

Two churches in the castle

The Iburger Schloss houses two churches, the Catholic St. Clemens Church and the Evangelical Lutheran Castle Church.

St. Clement's Church

St. Clement

The Catholic St. Clement's Church, a three-aisled hall with a transept and rectangular choir, goes back to Bishop Benno II, who also found his grave here. The current shape of the church dates from the 13th century. The church received a baroque interior during the construction period of the Westphalian baroque master builder Johann Conrad Schlaun . However, it was largely abandoned in 1890 in favor of the neo-Gothic. After the abolition of the monastery in 1803, the church was used as a powder magazine for four years, then the Catholic community took it into use, but it was not transferred to the parish until 1836. A structural feature of the church is the medieval hagioscope , a so-called leprosy fissure.

Church records

The church books of St. Clemens were copied from the beginning until 1876 and processed into the local family book. The Iburg local family book can be viewed in the library of the Osnabrück Family Research Working Group.

Evangelical Lutheran Castle Church

Ernst August von Braunschweig-Lüneburg had the Evangelical Lutheran Castle Church, the original Baroque furnishings largely preserved, built in in 1664. As a court chapel, it initially only served the bishop and his entourage. It was only accessible through the prince's wing inside the castle. It was inaugurated on May 1, 1664. The parish sermon was held by Magister Wilhelm Stratemann. In 1674 Ernst Georg Wöbeking became the first Protestant pastor, who was not only responsible for the members of the court, but also for the Protestant Christians in Iburg themselves. After Ernst August's death, his Catholic successor had the church closed. According to the alternating succession , Ernst August II succeeded him in 1716 as Protestant sovereign. He had the church renovated and reopened. In 1728 another Catholic sovereign followed, Friedrich , the second eldest son of Georg III. from Great Britain.

The staircase of the castle church added in 1913
The Evangelical Lutheran Palace Church is located on the first floor of the south wing above the gate

The Protestant community received its own parish rights in 1814. A separate entrance was created for them. In 1913 the Klotzbahn added a staircase in the Neo-Renaissance style, donated by Berta von Bardeleben. Your coat of arms is in the leaded glass window of the staircase. On May 1, 2003, the parish celebrated the 340th anniversary of the castle church with a ceremony.

Clergy of the Evangelical Lutheran Castle Church since 1905:

  • 1905–1911 Pastor Franz Theodor Wesenack
  • 1911–1949 Pastor Karl Wilhelm Thimme , professor at the University of Münster
  • 1949–1960 Pastor Günther Herbst
  • 1961–1977 Pastor Christian Walter Schulze
  • 1977–1990 Pastor Günther Robert Aden
  • 1990–1994 Pastor Uwe Höppner
  • since 1994 Pastor Angelika Schmidt

After 19 pastors, the church has a pastor for the first time.

Knight hall

The knight's hall of the castle, measuring twelve by 15 meters, was created as a hunting and dining room by Prince-Bishop Philipp Sigismund von Braunschweig-Wolfenbüttel in the first decade of the 17th century, but was badly damaged during the Thirty Years War from 1633 to 1650 under Swedish occupation.

Today's baroque furnishings from 1650 to 1661 were commissioned by Franz Wilhelm von Wartenberg from the architect Johann Crafft († 1667). The ceiling painting from the years 1656 to 1658 by Andrea Alovisii with Zeus in the center, framed by the heroic deeds of Heracles , is an outstanding example of perspective architecture. It is the only one of its kind that has been preserved in the original north of the Alps. Only the ceiling painting of the Munich Residence, which was destroyed in the Second World War , was older . 73 portraits on the walls show the Osnabrück bishops in the Iburg and rulers.

The stone floor with blue-black and white-gray tiles laid in a diamond shape symbolize the Bavarian coat of arms of Franz Wilhelm von Wartenberg. The floor was reconstructed in 1997 after the knight's hall had been equipped with a wooden floor for many decades.

In the knight's hall, the exhibition Between sumptuous dishes and clothesline - the reconstruction of the knight's hall in the Iburg is shown. It is accessible at palace concerts, guided tours and other public events.

In autumn 2004 a scientific conference dealt with the knight's hall and the residence period under Prince-Bishop Franz Wilhelm von Wartenberg for the first time. The contributions to the conference, including all images of the bishops, were published in 2007.

Castle Museum

The castle museum, which was reopened in 2002 after a fundamental redesign, shows the exhibition Fortification, Bishop's Residence, Monastery - Archaeological Research on the 1200-year-old Iburg . It describes the history of the origins of the castle and monastery complex. The history of the building is illustrated with a model of the complex showing the castle and monastery around 1600. Exhibits from excavations by the city and district archeology of Osnabrück include a thebal ring , abbot's staff, parts of a crossbow from the high Middle Ages and everyday objects such as pens, floor tiles and ceramic containers. The Schlossverein Iburg e. V.

In the Münzkabinett, part of the castle museum, coins and medals from 800 years of coin history in the Osnabrück region are on display. In 2005, the Schlossverein received from the Landschaftsverein Osnabrücker Land e. V. a coin and a medal with direct reference to the Iburg on permanent loan to the Münzkabinett. The Klippe zu 1 Reichstaler is a rectangular coin with one-sided embossing of the bishop's coat of arms, which the Osnabrück cathedral chapter had the cathedral chapter minted in 1633 under the Catholic prince-bishop Franz Wilhelm von Wartenberg as emergency money from the pen silver. The Swede Karsteen Arvid, one of the most important medalists of his time, coined silver medals on the occasion of the wedding of Sophie Charlotte, who was born in Schloss Iburg . At the age of 16 she was married to the then Brandenburg Elector Friedrich . The commemorative medal from 1684 in the Münzkabinett shows on one side the bust of Sophie Charlotte, on the other side the bust of Frederick, who later became King of Prussia, with an allonge wig.

Knot garden and castle meadow

On the south side of the Schlossberg, the knot garden from the 16th century was reconstructed in 2013 . Trees were felled for the 3,500 square meter garden and new paths to the palace and Charlottensee were laid out. The knot garden, formed from strands of boxwood , is framed by sandstone walls and benches. A promenade made of rose arches forms a cross connection to the castle mill.

The Schlosswiese, laid out as a sports field by students from the Lower Saxon Home School Iburg after the end of the Second World War , was added to the spa park on the Charlottensee and redesigned. The plant turned out to be more difficult than expected because pollutants were found on the area of ​​the former cinder track.

The northern slope of the Schlossberg is also to be redesigned.

Use of Iburg Castle

After the secularization , the Prince Diocese of Osnabrück and Iburg Castle and the monastery finally passed to the Welfenhaus. In 1866 Hanover became a Prussian province, with Iburg Castle also becoming Prussian. Iburg Castle is now owned by the State of Lower Saxony.

Bad Iburg District Court

The Iburger Schloss is the seat of the Bad Iburg District Court .

1885 to 1945

From 1885 Castle Iburg was the seat of the Iburg district administration. The Iburg district was dissolved in 1932. The storm department of the NSDAP operated an SA sports school in the castle complex from 1934 to 1939. From 1942 to Easter 1945 it was home to the Iburg Castle German Home School , which pursued National Socialist educational goals. It was the first secondary school in what was then Flecken Iburg and, in addition to boarding school students, accepted boys as external students and, in a limited number, girls with particularly good grades.

Lower Saxony home school (1948 to 1971)

From 1948 to 1971 the castle was used as the Lower Saxony home school Iburg . The six home schools in the state of Lower Saxony, including the Iburg boarding school, were primarily intended to enable children from refugee and displaced families to attend the grammar school. In the first few years, 90 percent of boarding school students came from refugee families. The Iburger Heimschule was a grammar school in short form (GiK). In 1971 the school was transferred to the Osnabrück district and converted into a half-day school. The boarding school was closed. The grammar school moved to the new school center in August 1972.

Until then, many Iburgers had sent their children to high schools in Osnabrück rather than external students, regardless of the hardship for the learner drivers. For some Iburgers, the grammar school was, in short, not demanding enough. Nevertheless, almost two thirds of the students at home school in recent years were external.

Police School of the State of Lower Saxony (1973 to 2004)

Entrance to the district court in the castle

From 1973 to 2004 the Lower Saxony police trained some of their youngsters in the castle. The teaching operation as an external location of the Lower Saxony State Police School with headquarters in Hann. Münden began on October 1, 1973 with two classes as a basic training course for police candidates.

In May 1997 the police school became a branch of the educational institute of the Lower Saxony police, which emerged from the state police school. When the educational institution celebrated its 30th anniversary at the Bad Iburg site in October 2003, the discussion about the future of the castle was in full swing. Horst Denningmann, head of the Bad Iburger Police School from 1975 to 1988, expressed the hope at the festive event in the knight's hall of the castle that the next anniversary could still be celebrated here. Although the state of Lower Saxony decided against selling the castle, the hope that the educational facility for the police would be preserved was not fulfilled. On April 23, 2004 the last advancement course ended here. The property management was transferred to the Lower Saxony Ministry of Culture.

Lower Saxony school inspection

From May 2005 to December 2010 Iburg Castle was the official seat of the Lower Saxony School Inspectorate .

Landscape Association Osnabrücker Land

Court pharmacy

From May 2006 to December 31, 2019, the cultural institution used the former court pharmacy at Iburg Castle with its office. Erected around 1600, the building connects the castle and monastery areas as part of the old double complex. A stone fireplace (with the initials of Prince Bishop Philipp Sigismund von Braunschweig-Wolfenbüttel and the year "1600") and a few remains of the original wall plaster have survived from the time it was built. The Landschaftsverband Osnabrücker Land is responsible for regional cultural funding in the city and district of Osnabrück, for example through financial support or through its own projects. The scientific development of Castle Iburg is one of the main topics of the association.

State Construction Management Osnabrück-Emsland

Since October 2011 Schloss Iburg has been the headquarters of the Osnabrück-Emsland State Construction Management.

Castle concerts

The palace concerts have been held in the knight's hall for more than 30 years. The concert series was initiated by the music teacher Harry Jahns to breathe new life into the knight's hall. The first concert took place on November 29, 1975. The program essentially features classical, romantic and early 20th century music. The German Music Council mediates the Iburger Schlosskonzerte e. V. talented young artists. The clarinetist Sabine Meyer is one of the internationally known artists who performed in Bad Iburg at the beginning of their careers .

Night lighting

Castle lighting association

The palace lighting association, founded in 1972, provides the palace with lighting. He has made it his business to help restore the former abbey gardens.

Courage price

The Courage Prize has been awarded once a year in the Knights' Hall of the castle since 1996 . It honors people and institutions who have rendered services to the common good . The first prize winner in 1996 was Harry Jahns, the artistic director of the palace concerts. The most prominent award winner in 2009 was Queen Silvia of Sweden as the founder of the World Childhood Foundation.

Warrior Memorial

cenotaph

On the southern castle wall there is a war memorial, created by the Osnabrück sculptor Fritz Szalinski, at the site of the former legge . The Legge building, a half-timbered house, was demolished in 1968 during an exercise by the volunteer fire brigade.
