Originally the Monastyrka as well as the Volkovka river were part of the Black River. The mention of this river goes back to the 1500's.

With the direction of the river flow reversed: it began to flow out of the Neva and into the flow channel.

The high banks of the river were strengthened by stemming wooden piles with zabirnymi walls, from the Neva to the Monastery. The steep slopes of the coast is often blurred, jeopardizing the existence of historic cemeteries necropolis: Lazarevsky and Tikhon. The first coastal protection banquet low wall began in the area between the Obukhovskoy Defense and monastery bridges in 1963, in conjunction with the construction of bridges.
