Neglinnaya River
The East side of the Kremlin triangle, lying adjacent to Red Square and situated between the rivers Moskva and the now underground Neglinnaya River was deemed the most vulnerable side of the Kremlin to attack, since it was neither protected by the rivers, nor any other natural barriers, as the other sides were. Therefore, the Kremlin wall was built to its greatest height on this side, and the Italian architects involved in the building of these fortifications convinced Ivan the Great to clear the area outside of the walls to create a field for shooting. The relevant decrees were issued in 1493 and 1495. They called for the demolition of all buildings within 110 sazhens () of the wall.
