Konzertsaal Solothurn, Concert hall in Solothurn, Switzerland

Konzertsaal Solothurn is a concert house designed by Alexander Koch in 1896, modelled on the Swiss National Museum in Zurich. Inside are the Grosser Konzertsaal of 210 m² seating 590 and the Kleiner Konzertsaal of 130 m² seating 200, with a foyer at the entrance. It stands at Untere Steingrubenstrasse 1, north of the old town near the Kunstmuseum.

Swiss architect Alexander Koch designed the building in 1896, taking inspiration from the Swiss National Museum in Zurich. The project was created when Solothurn was establishing itself as an important cultural center in the region.

The venue has served as the heart of the Solothurner Filmtage festival since 1990, hosting both musical and film presentations throughout the year. It has become a gathering place where local and visiting audiences experience contemporary and classical arts together.

The hall stands at Untere Steingrubenstrasse 1 in the northern green belt, just north of the old town and near the Kunstmuseum. The entrance area holds the foyer, from which the Grosser Konzertsaal (210 m², 590 seats) and Kleiner Konzertsaal (130 m², 200 seats) are reached. The site occupies ground where the city's fortifications once stood.

The hall stands on the site of Solothurn's former ramparts, north of the old town. Its model was the Swiss National Museum in Zurich, and after completion it was counted, together with the Kunstmuseum next door, among the city's two new cultural centres.
