To the north of the Cathedral of the All-Merciful Savior, next to the two-story building of the brotherhood's cells, which is located along the northern wall of the monastery, stands the so-called hospital church of All Saints. It was built in 1721 on the site of the dismantled cathedral bell tower and consecrated in honor of the Three Hierarchs. In the 1840s, after a major fire, the church was rebuilt and reconsecrated in honor of All Saints. In 1918, the church was closed and is currently not used for worship.
