Stadttheater Schaffhausen, Municipal theater in Schaffhausen, Switzerland

Stadttheater Schaffhausen is a performance venue in the city of Schaffhausen with an audience hall seating around 687 people and known for good acoustics throughout. The hall was designed so that sound carries evenly and pleasantly to every seat.

Merchant Johann Conrad Im Thurn donated 10,000 pounds sterling in 1864 so his hometown could unite music, art and education under one roof. The Imthurneum, built by architect Georg Friedrich Peyer im Hof on the site of the former municipal slaughterhouse on Herrenacker, opened on 16 January 1867 with a programme including Schiller's Jungfrau von Orleans. Its domed auditorium had 117 doors, earning it the nickname Zuglufttheater. In 1938 the city took over the building from the Thurn foundation; it closed in 1952 after stucco fell into the empty auditorium during a rehearsal.

The theater serves as a gathering place for drama, musical theater, and dance performances running from September through June. It shapes how locals experience and engage with the arts throughout the year.

The house sits on Herrenacker in the old town centre and seats up to 687 spectators. The season runs from September to June, with no performances in July and August. The building is owned by the city, which took it over in 1938, and the programme is subsidised by canton and city.

The hall's domed ceiling gave it an intimate acoustic, and its 117 doors earned the building the nickname Zuglufttheater, or draught theatre. The Imthurneum was built on the site of the former municipal slaughterhouse on Herrenacker, and the merchant Johann Conrad Im Thurn was made an honorary citizen of Schaffhausen for his donation.
