Bely Gorod
Bely Gorod (, "White City") is the central core area of Moscow, Russia beyond the Kremlin and Kitay-gorod. The name comes from the color of its defensive wall, which was erected in 1585–1593 at the behest of tsar Feodor I and Boris Godunov by architect Fyodor Kon'. The wall is in length, and its width ranges up to at its widest. Bely Gorod had 28 towers and 11 gates, the names of some of which are still preserved in the names of squares, namely: Trehsvyatsky, Chertolsky (Prechistensky), Arbatsky, Nikitsky, Tversky, Petrovsky, Sretensky, Myasnitsky, Pokrovsky, Yauzskiy, Vasilievsky. The walls  were cogged, like the Kremlin walls, with loopholes that allowed keeping a continuous fire. During the reign of Catherine the Great and her grandson Alexander I the wall was demolished and replaced by a chain of boulevards, known as the Boulevard Ring.
