When the monastery was established, Boris Godunov personally laid the foundation stone of its cathedral, consecrated in 1593 to the holy image of Our Lady of the Don. This diminutive structure, quite typical for Godunov's reign, has a single dome crowning three tiers of zakomara. In the 1670s, they added two symmetrical annexes, and a refectory leading to a tented belltower. Its iconostasis, executed in 1662, formerly adorned one of Moscow churches demolished by the Communists. From 1930 to 1946, the cathedral was closed for services and housed a factory.
