Kalyazin appeared in the 12th century as a sloboda, or the settlement for people relieved from paying taxes. The town’s importance grew significantly with the foundation of the Makaryevsky monastery on the opposite bank of the Volga in the 15th century. This abbey used to be the most conspicuous landmark of Kalyazin and comprised numerous buildings of historic interest, including a refectory from 1525. In 1940 the monastery and most of the old town were flooded during the construction of the Uglich Reservoir. After that, the town was effectively relocated to a new, higher spot.
