Forte Ospizio San Gottardo, Military fortress on the Gotthard Pass, Ticino, Switzerland

Forte Ospizio San Gottardo is a military fortress built between 1893 and 1894 consisting of two connected barracks buildings. The upper section now functions as a military museum, while the lower part continues to serve as troop accommodations.

Built in 1893–1894 as part of the Gotthard fortifications, Fort Hospiz was expanded until 1918 and again from 1937 to 1946. In 1947 it was decommissioned as a combat installation and has since served as troop accommodation and, from 1998, as a museum.

The museum opened on 25 July 1998 in rooms the army no longer used, after the decaying building fabric was repaired. It displays 12-cm Model 1891 armoured howitzers, 5.3-cm cannons, Maxim machine guns, 4.7-cm infantry guns and mortars, plus videos and historical photographs of daily work and the war of 1914–1918.

The exterior areas are open year-round, though some interior sections remain restricted due to active military use. Visitors should check opening hours in advance, as museum access varies seasonally and visitor numbers are sometimes limited.

The fort's 1900 armoured observation bell and the 5.3 cm travelling-carriage gun positions added after 1902 are easy to miss among the trenches. The whole pass zone counted around fifty objects, mostly infantry works, caverns and shelters, of which Fort Hospiz was one.
