Moscow Canal

The Moscow Canal, named the Moskva-Volga Canal until 1947, is a canal in Russia that connects the Moskva River with the Volga River. It is located in Moscow itself and in the Moscow Oblast. The canal connects to the Moskva River in Tushino, from which it runs approximately north to meet the Volga River in the town of Dubna, just upstream of the dam of the Ivankovo Reservoir. The length of the canal is 128.1 kilometres.

It was constructed between 1932 and 1937 by 200,000 gulag prisoners, under direction of the Soviet secret police and Matvei Berman.With the canal, Moscow is connected to Russia's Unified Deep Water System, a large system of canals and rivers in European Russia, which created access to five seas: the White Sea, Baltic Sea, Caspian Sea, Sea of Azov, and the Black Sea. As such, it is sometimes called the "port of the five seas".
