Take a trip up the Volga river in Russia and when you get to the small town of Kalyazin keep your eyes peeled for something unusual. There, in the middle of an artificial lake stands something a little perplexing.
During the 1940s the then Communist government had big plans to make the turbulent river navigable all year around. So a cascade of dams and reservoirs was ordered on the Upper Volga. It gave the region the much needed transport artery and hydroelectricity in to the bargain. It also buried hundreds of years of history, of which the bell tower of the Makaryevsky Monastery is the only visible remnant above the waters of the Uglich reservoir.
