is the centre of Russian economy, politics, and culture. The city was built many centuries ago by Yuri Dolgorukiy, the Rurikid prince. It is situated on the banks of the Moscow River. The Moskva River is a river of western Russia. It rises about 140 km (90 mi) west of Moscow, and flows roughly east through the Smolensk and Moscow Oblasts, passing through central Moscow. About 110 km (70 mi) south east of Moscow, at the city of Kolomna, it flows into the Oka River, itself a tributary of the Volga, which ultimately flows into the Caspian Sea. The river is 503 km (313 mi) long. The main tributaries are the Ruza, Istra, Yauza, Pakhra, and Severka rivers. Since completion of the Moscow Canal (1932–1937), the Moskva River has also collected a share of Upper Volga water.
