This 88m-high, five-layer bell tower is 6m taller than the Ivan the Great bell tower in the Moscow Kremlin and dominates the monastery and town. It took thirty years (1740-1770) and three architects (Shuumakher, Michourin and Ukhtomski) to carry out this bold project. This astonishing building creates an impression of lightness, highlighted by the openings all of the same size, as the storeys narrow progressively.
