The monumental Pokrovskaya Tower with diameter 90 meters is one of the largest defense structures of this kind in Europe. The forty-meter-high bulk with the first tier cut in the rock and the thickness of the walls at the base of about six meters has been guarding the southern borders of Pskov for 545 years.
Built in the 1470s taking into account the best engineering developments of the time, the Pokrovskaya Tower is equipped with special entrances, sitting in which a warrior could hear the sounds of undermining. The Randomyshskaya cannon - the main weapon of defenders of the fortress weighing four and a half tons stood on the third tier. In front of the tower the traces of the earth fortifications made by the order of Emperor Peter the Great in the course of the Northern War are still visible. Now the tower is completely restored and it organizes thematic exhibitions dedicated to the history of the Pskov Kremlin and the heroic past of the city.
