The Borovitskaya Tower (Russian: Боровицкая башня) is a corner tower with a through-passage on the west side of the Kremlin. It is named after Borovitsky Hill, one of the seven hills Moscow is standing on. The tower was constructed in 1490 on the spot of an old Kremlin gate by Italian architect Pietro Antonio Solari (Petr Fryazin, from fryaz or fryag as Italians were called at that time) by order of Vasili III of Russia. In 1658 by orders of tzar Aleksey I of Russia the tower was renamed to Predtechenskaya (from the Russian word предтеча — predtecha, the forerunner) after the Church of John the Forerunner, which was later destroyed during the construction of the Kremlin Armoury (Oruzheynaya Palata). The new name, however, never became popular. In 1812, the tower was damaged by an explosion staged by the retreating French army. In 1817-19, the tower was restored by architect Osip Bove. In 1935, the Soviets installed a red star on top of the tower. Together with the star, its height is 54.05 m.
