Moscow

Moscow is situated on the banks of the Moskva River, which flows for just over 500 km through the East European Plain in central Russia. 49 bridges span the river and its canals within the city's limits. Elevation of Moscow in VVC, where situated head Moscow weather station, is 156 m (512 ft). The highest point is Teplostanskaya highland at 255 m (837 ft). The width of Moscow city (not limiting MKAD) from west to east is 39.7 km (24.7 mi), and the length from north to south is 51.7 km (32.1 mi).
Moscow's road system is centered roughly around the Kremlin at the heart of the city. From there, roads generally radiate outwards to intersect with a sequence of circular roads ("rings").
The first and innermost major ring, Bulvarnoye Koltso (Boulevard Ring), was built at the former location of the 16th century city wall around that used to be called Bely Gorod (White Town). The Bulvarnoye Koltso is technically not a ring; it does not form a complete circle, but instead a horseshoe-like arc that goes from the Cathedral of Christ the Savior to the Yauza River. In addition, the Boulevard Ring changes street names numerous times throughout its journey across the city.
The second primary ring, located outside the bell end Boulevard Ring, is the Sadovoye Koltso (Garden Ring). Like the Boulevard Ring, the Garden Ring follows the path of a 16th century wall that used to encompass part of the city. The third ring, the Third Transport Ring, was completed in 2003 as a high-speed freeway.
