Architect Fyodor Kon, at the behest of Tsar Feodor and Boris Godunov, begins construction in 1585 on the stone walls of Bely Gorod (Russian: “White Town”), a fortress and settlement comprising the third defense belt around Moscow, which is to join the Kremlin and Kitay-gorod on the left bank of the Moskva River.

The walls are cogged, like the Kremlin walls, loopholes allowed to keep a continuous fire.
