Burg Tangermünde, Medieval castle in Tangermünde, Germany.

Burg Tangermünde is a castle built from red brick that rises on high ground above the Elbe River. Multiple defensive towers punctuate its structure, and it sits within the historic fortified walls that surround the town.

A border fortress existed here by around 925, first recorded in 1009 in Bishop Thietmar of Merseburg's chronicle. On 7 September 1373 Emperor Charles IV moved in after naming his twelve-year-old son Wenceslaus Elector of Brandenburg, and had the castle rebuilt as a residence the following year. Swedish troops burned it in 1640 during the Thirty Years' War; reconstruction began in 1902.

The castle chapel, first mentioned in 1371, became a collegiate foundation in 1377 under Charles IV. The site is now the Schlosshotel Tangermünde: the former Amtshaus of 1699, probably built on the foundations of the medieval Palas, serves as the hotel, and the Burghof is its terrace.

The 50-metre Kapitelturm, a former prison tower, has been open as a viewing tower on guided tours since May 2003. The castle courtyard serves as the hotel terrace, and the Old Chancellery belongs to the town and is used for events. The former Amtshaus probably stands on the foundations of the medieval palas.
