The district office of the Eichsfeld district is located in the former kurmainz. Stadthalterei, which was built from 1736-1738 in the Baroque style and is often referred to as the "castle". (Source: Information board on the building)
Actually, it is the old castle in Heiligenstadt where the district office is now located. In the midst of beautiful old buildings and right next to St. Martin's Church, a beautiful location was chosen for the administration.
