Museum im Zeughaus, Technology museum in Schaffhausen, Switzerland.

The Museum im Zeughaus is a technology museum housed in a former military arsenal that displays collections of military vehicles, uniforms, and technical equipment. The spaces contain over 50 operational vehicles and 21 tanks that document different periods of Swiss military engineering.

The Zeughaus auf der Breite was built in 1871/1872 to host a federal weapons depot, a plan that failed, so the buildings served as the cantonal arsenal. Building 5, a timber extension by architect Karl Werner, followed in 1915/1916. The museum opened there in 2005, uniting Karl Bauert's equipment collection, Martin Huber's guns and vehicles, and Jürg Zimmermann's brass instruments.

The exhibition halls show Swiss military life through figures, scenes, and objects spanning 250 years. These displays help visitors understand how military service shaped daily life and society.

The museum is run entirely by unpaid volunteers, who maintain the collections, mount exhibitions and lead guided tours. It occupies two sites: the historic Zeughaus buildings on the Breite in Schaffhausen and a former industrial building at Ratihard in Diessenhofen, right by the St. Katharinental SBB station. Since 2025 the historic motor vehicles, tanks and guns have been kept in Diessenhofen.

The museum maintains a collection of tanks and military vehicles in working condition that are rarely found in other Swiss museums. These operational vehicles are occasionally demonstrated and show the practical side of Swiss military engineering.
