Das Beste kommt zum Schloss

In the summer of 2025, the "Das Beste kommt zum Schloss" series once again brought several prominent acts from music and cabaret to the Schlossberg. The concept — a few, but carefully selected evenings instead of a condensed multi-day festival — is considered the series' recipe for success and secures it a loyal regular audience from the entire Siegen-Wittgenstein district.

Integrated into the cultural summer program of Kultur! Siegen, other open-air formats such as the Grüne Bühne in the Herrengarten and Sonntagnachmittag um 4 in the tent arena complemented the offerings. This creates a dense cultural network throughout the summer, providing programming for the Siegen city center.
