Lake Onega

Lake Onega is the second largest lake in Europe.

The lake has about 1,650 islands, with Kizhi being the most famous for its historical wooden churches.

The Uspenskaya Church in Kondopoga was the tallest wooden church of the Russian North before its destruction in 2018.

The Onega petroglyphs, located on the eastern coast of the lake, date back to between the 4th and 2nd millennia BC.

The lake's water is fresh, with a salinity of 35 mg/L, which is relatively low compared to other large lakes in the area.
