Mologa is a Russian city of notorious history. In 1935, when a new hydro power station was being built there, it was severely flooded and was fully submerged by 1947. It had been a big and prosperous city in the end of the
XIX century, by the way. That's why even after the flood many interesting churches were preserved to the present day. Some of them are rather monumental, others, on the contrary, look very sophisticated.
