Moscow Kremlin Walls
The red-brick fortress enclosing Russia's seat of power/World Landmarks
The Moscow Kremlin walls, built between 1485 and 1495, form an irregular triangle enclosing 27.5 hectares of fortified citadel on a hill above the Moskva River. The red-brick walls stretch 2,235 m in total length, vary from 5 to 19 m in height, and are 3.5 to 6.5 m thick. Twenty towers punctuate the walls, with the tallest (Trinity Tower) reaching 80 m. The walls originally had merlons in the distinctive swallow-tail Ghibelline pattern, reflecting the Italian architects (primarily Pietro Antonio Solari) who designed them.
