One of the most interesting sights of the Tver region is located in the county town of Kalyazin, which in 1940 was almost completely flooded during the creation of the Uglich water reservoir. The whole old town, monastery and merchant chambers went under water, and over the surface of the newly formed reservoir only the high bell tower of St. Nicholas Cathedral remained, now serving as a beacon for the Volga ships. Sometimes prayers are held in it, and in the summer you can hear the ringing bell, spreading for kilometers around and creating a very special atmosphere of the distant Russian hinterland.
