Most of the existing major monastery buildings were constructed of stone between 1651 and 1667. The entire complex is surrounded by a fortress-like stone wall with towers, forming a square with each side being about 200 meters long. The notable buildings of the period include the (rebuilt) Cathedral of Holy Trinity (1658), the Church of the Dormition of Our Lady (the Uspensky Church) with the large attached refectory ("trapeznaya") (1651), the bell tower (1651), the Church of St. Michael the Archangel above the southern gate, and the monastic cells. The refectory is a large (420 m²), two-storied building.
