History of Construction
The site of the present kremlin was originally occupied by a wooden fortress built in the early 14th century. It suffered repeatedly from fires and Horde raids. In 1525 Grand Prince Vasily III decided to replace it with a stone citadel. The Moscow Kremlin served as the model, and Italian masters were brought in for the construction, presumably including Aloisio the New. Work went on for six years, and in 1531 Kolomna gained one of the most powerful fortifications in Rus.
