Granovitaya Tower, 16th-century defensive tower in Kolomna, Russia

Granovitaya Tower is one of the seven towers of the Kolomna Kremlin that survive today, built in 1525–1531 and standing between the Kolomenskaya (Marinkina) Tower and the Ivanovskiye Gates. Its plan combines a hexagon and a square: the outer face is shaped as a hexagon, while the inner, Kremlin-side part is a parallelepiped. That shape gave the tower its name.

The tower was built between 1525 and 1531 as one of the seven towers of the Kolomna Kremlin that survive today. It stood between the Kolomenskaya (Marinkina) Tower and the Ivanovskiye Gates, guarding that stretch of the fortress wall.

The tower is used by the Svyatogor Centre of Russian Military Culture, which holds its classes and training sessions inside the building. The name Svyatogor refers to a giant warrior of Russian epic tradition. Visitors passing the tower may see members of the centre at work there.

Granovitaya Tower stands between the Kolomenskaya (Marinkina) Tower and the Ivanovskiye Gates, so it is reached on foot along the Kremlin's inner wall line. The tower is occupied by the Svyatogor Centre of Russian Military Culture, whose classes take place inside, so check access before planning a look inside.

The tower's name comes from its plan: the outer face is a hexagon, while the Kremlin-side inner part is a rectangular parallelepiped, giving the structure a faceted look. It stood between the Kolomenskaya (Marinkina) Tower and the Ivanovskiye Gates.
