The Kiev Fortress (Ukrainian: Київська фортеця; Kyivs'ka fortetsia; Russian: Киевская крепость; Kievskaya krepost' ), also known as the Pechersk Fortress, is a generic name for the 19th century fortification buildings situated in the Ukrainian capital Kiev, that once belonged to the system of western Russian fortresses. These structures (once a united complex) were built in the Pechersk and neighbourhoods by the Russian Imperial army. Now some of the buildings are restored and turned into a museum called the Kiev Fortress, while others are in use by various military and commercial installations.
