history

Auerhof / Villa Carstanjen

The castle-like property goes back to the "Plittersdorfer Aue" or the "Auerhof", a front yard of the Heisterbach monastery . According to documents, the monastery had partially acquired the farm as an allod in 1197 and in full in 1318. The core of today's building was built in the 18th century. In the course of secularization (1802), the court came into state ownership and was acquired by the banker Abraham Schaaffhausen on February 24, 1807 .

As a so-called villa rustica, the Auerhof had extensive commercial land holdings, in 1824 over 490 acres , which were managed by tenants. The garden belonging to the villa covered an area of ​​25 acres and had orchards and greenhouses that had been laid out at the instigation of Schaaffhausen and his daughter Sibylle . After Schaaffhausen's death in 1824, the property became the property of his daughter Sibylle and her husband Joseph Ludwig Mertens . As a result of the death of her husband in 1842, Sibylle had to sell the Auerhof. The Solf family became the new owners in 1847.

In 1881 the Cologne banker Wilhelm Adolf von Carstanjen (1825–1900, ennobled in 1881) acquired the villa and made it his summer residence, which he only used for a few years and which he handed over to his son Robert at an early age. Presumably in connection with his ennoblement, he converted the farm to entails . He and his son Robert had the current palace built in place of the existing building through multiple modifications: in 1892 an extension in neo-Gothic forms according to plans by the architects August Hartel and Skjøld Neckelmann (1854–1903), 1895–1896 an extension according to plans by the Cologne architect Johannes Baptist Kleefisch around a hall extension on the southeast corner and a kitchen extension on the southwest corner as well as 1906–1907 an extension of the old house. Under the Carstanjen family, the property was once again used as a villa rustica and was continuously expanded through land acquisitions, with the focus on apples and plums. On behalf of Adolf von Carstanjen, a new drying house was built in 1894 , on behalf of the son in 1908 a greenhouse and in 1918 an 80 m long wall for trellis fruit . After completion of the renovation, the villa was designated as a castle by the owner Robert von Carstanjen in 1907 and the courtyard with an area of ​​now 127  hectares as a manor . Carstanjen used the property as a permanent residence in the last years of his life. After his death, his widow sold the Auerhof on August 11, 1941 to the Reich Treasury (Army), and it subsequently served as an Army Teachers Academy.

Seat of federal institutions

In World War II house Carstanjen remained undamaged and was after the war by Allied occupation forces confiscated . After Bonn was designated the seat of government of the Federal Republic of Germany in 1949, after its release from confiscation in mid-November 1949, the state of North Rhine-Westphalia offered the federal government to accommodate the Federal Ministry for Affairs of the Marshall Plan ("ERP Ministry"). After the approval of the Federal Minister of Finance at the beginning of December 1949, immediate investments of 200,000  D-Marks and later another 311,000 DM were made, among other things in the outdated water pipes and heating systems of the house.

From 1950 until its dissolution in 1969, Haus Carstanjen housed the ERP Ministry, later renamed several times (most recently "Federal Treasury"), at times also part of the Federal Ministry for Building, Regional Planning and Urban Development with 120 employees (status: 1974) and until 1996 several departments of the The Federal Ministry of Finance has taken the place of the Federal Treasury . After the remaining stables and barns with the greenhouse were demolished, from 1967 to 1970 for the Federal Ministry of Treasury according to a design by Manfred Adams as a member of the planning group of the Federal Building Directorate (later Stieldorf planning group ) and with the artistic advice of Sep Ruf at costs of around 12, 5 million DM an extension consisting of four buildings was erected. In the 1970s, the Carstanjen family sold the land to the federal government, parts of which are now integrated into the Rheinauenpark .

In 1996 the entire complex became the domicile of the UN organizations based in Bonn and newly settled here this year. The building, which was previously not fenced, was surrounded with a fence and equipped with security cameras. The canteen has not been open to the public since then. The then UN Secretary General Boutros Boutros-Ghali inaugurated the new UN site on June 20, 1996. Initially, from July 1, 1996, the Volunteer Program (UNV), the Regional Information Center ( UNRIC ), on August 12, the Secretariat of the Framework Convention on Climate Change (UNFCCC) and on August 5/6. December the Secretariat of the Convention for the Conservation of Migratory Wildlife Species (CMS) , which had previously been based in Bonn, initially had a total of around 200 employees at Carstanjen. While more and more UN institutions moved into the building, the federal government renovated it for seven million euros. In spring 2006, the majority of the organizations in the Langen Eugen moved to bring them closer together spatially (“ UN campus ”). Part of the climate secretariat initially remained in the Carstanjen house . From 2008 to 2011 renovation and renovation measures were carried out there at a cost of 4.5 million euros. In 2010, a security fence was built around the site at the instigation of the UN Department of Security and Safety . On January 1, 2016, the Knowledge Center for Sustainable Development of the Turin- based Training Academy of the United Nations System ( UNSSC ) started its work in the Carstanjen house .

architecture

Rhine side from House Carstanjen

The old building consists of an angular, three-storey structure on which two round towers are placed.

The new building, erected from 1967 onwards, consists of two three-storey, longitudinally rectangular buildings, one behind the other, a seven-storey high-rise in front and a flat canteen building. The latter is connected to the skyscraper and the old building via walkways, the wooden structure is completely glazed. A subdivision into a café and restaurant is only achieved by a free-standing brick wall . The office buildings are made of reinforced concrete frame construction, with steel walkways in front of them, vertical sun protection tubular steel rods.

"The compositional interplay of the differently dimensioned, filigree structured structures unfolds a great plastic effect in the park of the castle."

- Andreas Denk : (1997)

"The contrast of the Gothicized old house with the cool new buildings made of steel and reinforced concrete in the old park is very attractive."

- Ingeborg flag : (1984)

Carstanjen Park

The park, located south of Haus Carstanjen, has a size of approx. 27,000 square meters and is open to the public. The park is characterized by a diverse and partly very old tree population. Since numerous trees were felled in 2020, a residents' initiative has been formed that is committed to maintaining the tree population and replacing felled trees.

Carstanjen mausoleum

In 2005, the Carstanjen family's mausoleum, about 350 meters further south, was bequeathed to the Rheinviertel community foundation . After a two-year renovation phase that took 300,000 euros to complete, the tomb, which had been neglected for decades, became a modern necropolis in 2007 that can hold up to 3,000 urns.
