The City Arsenal (Ukrainian: Львівський міський арсенал, romanized: Lvivskyi miskyi arsenal, Polish: Arsenał Miejski we Lwowie) is the oldest of three historic arsenal buildings in Lviv, Ukraine. The other two are the Royal Arsenal and Sieniawski Arsenal. It is a rectangular two-storey structure with a miniature octagonal tower on the north side. The building, in its present shape, was erected in 1554–56 above a 14th-century structure of unknown function. It was formerly attached to the city walls and featured a torture chamber. The arsenal building was blown up by the Swedes during the Great Northern War but was subsequently restored. At present, it houses an armoury museum.
