Stürmt die Burg — Wilhelmsburg Culture Festival

Ulm Summer Festival in the Fortress

'Stürmt die Burg' has established itself as one of southern Germany's prominent summer festivals since its first edition in 2018. The combination of an extraordinary location (19th-century fortress), a broad cultural program (music, theater, readings, art), and its pop-up nature (only three weeks per year) makes the format unique.

The 8th edition in 2025 once again brought national and international artists to the Wilhelmsburg, complemented by the Open Tower program with its interactive installations and open studios. The rooftop bar was again a meeting point for regular visitors and new guests — evening sunsets over the Minster and the Danube plain have become a trademark.
