The history of the Cassian Uchemsk Monastery dates back to the second half of the 15th century, when the Greek prince Konstantin, who took monastic vows under the name Cassian, founded a monastery at the site where the river Uchemka flows into the Volga. In the first half of the 20th century, the monastery was destroyed, and the high bank on which it stood turned into a narrow spit in shallow waters. On the hill made of brick remnants from the Assumption Cathedral, near the resting place of the relics of Saint Cassian, a commemorative cross was erected in 1989, and in 1993, a memorial chapel was built. Since 1994, a church in honor of Saint Anastasia the Deliverer and Saint Cassian of Uglich has been functioning in the former monastery settlement. Nearby, there is a museum dedicated to the history of these places.
