Moscow Kremlin
Buildings
The existing Kremlin walls and towers were built by Italian masters from 1485 to 1495. The irregular triangle of the Kremlin wall encloses an area of 275,000 square metres (2,960,000 sq ft). Its overall length is 2,235 metres (2,444 yards), but the height ranges from 5 to 19 metres (16 to 62 ft), depending on the terrain. The wall's thickness is between 3. and 6.5 metres (11 and 21 ft). Originally there were eighteen Kremlin towers, but their number increased to twenty in the 17th century. All but three of the towers are square in plan. The highest tower is the Troitskaya, which was built up to its present height of 80 metres (260 ft) in 1495. Most towers were originally crowned with wooden tents; the extant brick tents with strips of colored tiles go back to the 1680s.
