The corner tower with a round cross-section was, perhaps, the most beautiful in the Kremlin before the construction of the hipped superstructure of the 17th century. The tower was built by Antonio Gilardi in 1488 as one of the first structures to protect the approaches from the Moscow River. Many innovations were used in the design of this tower: in Russian serf architecture, arcature belts, machicolations and “dovetails” had not been used before. The tower received its first name – Sviblova – after the surname of the owners of the courtyard adjacent to it. In 1633, a water-lifting machine by Christopher Galovey was installed in the tower, which gave it its modern name. This device, which became the first water supply system in Moscow, supplied water to the Sytny and Kormovoy palaces, and later to the Kremlin gardens. In 1812, the tower was blown up by the French, but already in 1819 it was restored under the leadership of O.I. Beauvais.
