The Neva and the numerous canals give St. Petersburg its special charm. They are witnesses of the history.

☞ THE MOYKA
The Moyka (or Moika) is a small river. It starts from the Neva and the Fontanka in the northeast near Summer Palace, crosses Nevsky Prospect, and meets Admiralty Canal and rejoins the Neva at the New Holland Island in the southwest.

New Holland Island (left: Admiralty Canal; right: the Moyka)
Created in 1719, the island fell into disgrace at Soviet time. An art project by Roman Abramovich for the island was approved in 2010.
☞ GRIBOYEDOV CANAL
Lying between the Moyka and the Fontanka, Griboyedov Canal starts from the Fontanka at Place Repin in the southwest, passes by Conservatoire Rimsky-Korsakov, Sennaya Place, crosses Nevsky Prospect at Kazansky Bridge, then greets Church of the Saviour on Blood and its millions of tourists, before joining the Moyka in the northeast at Field of Mars. Crime and Punishment opens, in its very first sentence, with a young man (Raskolnikov) walking towards Griboyedov Canal.
