The existing Kremlin walls and towers were built by Italian masters over the years 1485 to 1495. The irregular triangle of the Kremlin wall encloses an area of 275,000 square metres (68 acres). Its overall length is 2,235 metres (2,444 yards), but the height ranges from 5 to 19 metres, depending on the terrain. The wall’s thickness is between 3.5 and 6.5 metres.
