Burgmuseum Schlossfreiheit, History museum in Tangermünde, Germany

Burgmuseum Schlossfreiheit is a museum housed in a 1543 building that shows the history of the medieval castle and its residents. Four exhibition rooms present objects and information about how this fortress-like structure developed over several centuries.

The house was built in 1543, as an inscription on the building records, and is the oldest surviving dwelling in Tangermünde. Its upper storey dates from the 17th century. The museum opened here in 1998 and covers the neighbouring castle, especially its precedence under Emperor Charles IV in the 14th century, its time as a Brandenburg office in the 16th and 17th centuries, and the office's abolition in the 19th century.

The museum occupies four rooms of the house and traces the castle next door: its precedence as a princely seat under Emperor Charles IV in the 14th century, its running as a Brandenburg electoral office in the 16th and 17th centuries, and that office's dissolution in the 19th. It also covers the two monuments on the castle grounds, erected in the early 20th century.

The museum occupies the corner house at Schloßfreiheit 5, where the street Amtsgarten meets it from the east; the neighbouring Burg Tangermünde lies just to the east. The entrance is through a brick seating-niche portal, and the exhibition is spread over four rooms. The barrel-vaulted cellar and the 17th-century staircase belong to the original interior.

Two medallion portraits of the Krull brothers are carved into both sides of the entrance door, showing who originally built the house. These detailed stone reliefs are still clearly visible today and reveal much about the craftsmanship of that era.
