The Kiev Fortress is a complex of Russian fortifications in Kiev, Ukraine built over the span of 17-19th centuries, soon after the 1654 Council in Pereyaslav.
Kiev Fortress once belonged to the extensive system of western Russian fortresses that existed in the Russian Empire. The Kiev Fortress complex features many separate fortifications in Pechersk, Old Kiev, Podil, and Zvirynets located in various city districts of Kiev. Currently most of the remaining structures turned into a historic reserve. The main fortification associated with the Kiev Fortress (where located the Historic and Architectural Museum) is the Hospital fortification.
