62. Kalyazin, Russia

If you’re rushin’ to Russia here is another special spot to add to your potential itinerary. Oh, what’s even better is you do not necessarily need to be a scuba diver to explore the Kalyazin ruins either. The city’s cathedral belfry towers high over the water.

Once significant as an important commercial center, it began to lose its importance following a revolution in 1917. Decades passed and it became all but insignificant. Thus in 1940 the powers that be decided to relocate the locals to higher ground and sink most of the city in order to construct the Úglich reservoir.
