Oberes Schloss Singen, Archaeological museum château in Singen, Germany

Oberes Schloss Singen is a three-story castle building with a mansard roof located near the town hall in Singen. The structure now houses the Archäologische Hegaumuseum with collections documenting the natural history and archaeology of the region.

Franz Josef von Enzenberg built this castle between 1809 and 1810 after acquiring the land through marriage. Over time the building became an important place for preserving regional history.

The building is also known as Schloss Singen or Enzenbergsches Schloss, after the family that built it. Since the museum opened, 13 rooms have shown how people lived in the Hegau from the end of the last ice age, about 15,000 years ago, to the early Middle Ages.

The museum occupies 13 rooms of the castle, with the fossil, mineral and butterfly collection in the basement. It stands directly beside Singen's town hall, so it can be combined with a walk through the town centre. Allow time for both floors.

The basement holds a separate collection of fossils, minerals and butterflies, distinct from the archaeological displays in the 13 upstairs rooms. The building itself is the Enzenbergsches Schloss, built 1809–1810 for Franz Josef von Enzenberg, who came into the property through marriage.
