Burgfestwoche Bad Belzig with Altstadtsommer

A tradition since 1960

The Burgfestwoche Bad Belzig is one of Brandenburg's oldest civic festivals. Since 1960, the Bad Belzig festival association has invited visitors every August to a week-long festival centered around Burg Eisenhardt – the medieval hilltop castle on a hill at the edge of the old town. In 2026, the town will celebrate the 63rd edition of this traditional Brandenburg event.

Burg Eisenhardt

Burg Eisenhardt is the landmark of Bad Belzig and Brandenburg's largest preserved medieval fortress. Today, it houses a museum, a hotel, and a youth hostel – during the festival week, it becomes the central stage with concerts and events in the castle courtyard.

Festival Week Program

A diverse program is spread over the eight days:

• Sport — Table tennis tournament, stock-schießen (a type of curling), traditional sports competitions
• Concerts on the castle and market stage
• Art and exhibitions in Bad Belzig galleries
• Soapbox derby with children and adults
• Festival parade through the old town
• Gastronomic stands in the market square

Altstadtsommer as the Highlight

The Altstadtsommer on the last weekend of August marks the conclusion. This major town festival transforms the historic old town around the market square and Bahnhofstraße into an open stage with live music, a craft market, children's activities, and street food. In 2026, the 24th edition of the Altstadtsommer will take place.

Fläming and Bad Belzig

Bad Belzig is located in the Hoher Fläming – a hilly natural landscape southwest of Potsdam, known for the Burgenstraße (Castle Road), the SteinReich adventure world, and Brandenburg's largest contiguous hiking area. The state of Brandenburg and the Potsdam-Mittelmark district support the event as a cultural flagship of the region.
