The Neva River
Time of appearance: About 3.5 thousand years ago.
Name Origin: There are many versions, but none of them is supported by sufficient evidence.
Floods: For more than 300 years of St.Petersburg history, there were more than 300 floods in the city. Today floods is the question of the technical fixation. Reducing the destructive power of floods is a result of the construction of a dam across the Gulf of Finland and Kronstadt. In the Imperial epoch, floods were a very real threat. During the highest flood in the history of the city, which took place in 1824, the river rose more than 4 m, and it took away hundreds of lives.
Interesting facts: Swimming in the Neva River is strictly forbidden because of pollution, very fast flowing and many whirlpools. However, the main beach of St. Petersburg is located right beneath the walls of the Peter and Paul Fortress. The Walls heated by the sun very quickly, so sunbathers can be seen even in winter. During the winter period Neva River freezes, so moving to the other side on the ice is forbidden also because of the fragility of ice. Sometimes you can see a small icebreaker, breaking the ice in the middle of the river, to prevent the possibility of switching from one bank to another. However, citizens are not only used the river as a natural crossing, but even rolling on the frozen river on skis.
