Haus Carstanjen

Haus Carstanjen is a castle on the River Rhine in Plittersdorf, Bad Godesberg, a district of Bonn, Germany.HistoryThe original building dates back to 1716. In 1881 Wilhelm Adolf von Carstanjen (1825–1900, ennobled 1881) acquired the building which he rebuilt into its present classical castle form. After 1950 it was occupied by the German Federal Government. From 1950 until 1957 it housed the Bundesministerium für Angelegenheiten des Marshallplanes (the Federal Ministry for the Marshall Plan), from 1957 until its dissolution in 1969 the Bundesschatzministerium (Treasury) and, until 1999, the Bundesministerium der Finanzen (Federal Ministry of Finance).In the 1970s the Carstanjen family sold the grounds to the Federal government, including what is now the Rheinauen Park, and more buildings were built. At this time the grounds took on the nickname 'Schiller Park', after the former federal finance minister and house Mr. Karl Schiller.Starting in 1996, after German reunification, many government ministries moved to Berlin, and the offices at Haus Carstanjen were assigned to United Nations agencies. The federal government renovated the complex at a cost of seven million euros. From the summer of 2006 many of the UN organisations relocated to a new campus in the renovated Langer Eugen tower, leaving the UNFCCC secretariat resident in Haus Carstanjen. In November 2015, the German Federal Government welcomed the United Nations System Staff College - Knowledge Centre for Sustainable Development in Haus Carstanjen.
