The tower leans slightly, with a deviation of approximately 20 centimeters from the vertical axis.
The original cathedral was built on a site that has been prone to flooding, which necessitated the eventual relocation of most of the monastery buildings before the reservoir's creation.
During the Soviet era, the tower was used by the local parachuting club as a training platform.
The structure contains 12 bells, the largest of which weighs approximately 1,000 kilograms.
The foundation is reinforced with concrete to withstand the mechanical pressure of ice shifting on the reservoir surface during winter.
The tower's architecture follows the late classicism style prevalent in Russia at the turn of the 19th century.
The Kalyazin Bell Tower is a 74.5-meter-tall neoclassical structure standing isolated in the middle of the Uglich Reservoir. Originally built between 1796 and 1804, it served as the bell tower for the Saint Nicholas Cathedral of the Kalyazin Makaryev Monastery. During the construction of the Uglich Dam in 1939-1940, the monastery complex was demolished and submerged to create the reservoir. The tower survived the flooding due to its structural height, while the cathedral and monastic buildings were razed. An artificial island was later created around the tower's base to prevent further erosion from ice and water currents. In 2021, the structure underwent a significant restoration process, including foundation reinforcement and masonry repair. It currently functions as a memorial and remains an active religious site under the supervision of the Tver Eparchy. The tower features five tiers and remains one of the most recognizable landmarks in the Tver region.
From the river embankment, specifically the area near the local pier, for a clear view of the tower reflecting in the water.
Arrange a boat trip from the local pier to get a close-up view of the island.
Visit during the early morning to avoid the arrival of tour groups from Moscow.
Bring binoculars if viewing from the shore to observe the intricate stonework on the upper tiers.
Do not attempt to swim to the island from the shore due to strong undercurrents and shifting water levels.
Accessible by boat only during the navigation season; usually closed for interior visits during late autumn and winter.
Visitors should dress modestly if entering the tower; shoulders and knees should be covered.
