Poshchupovo Monastery, Orthodox monastery in Rybnovsky District, Russia

Poshchupovo Monastery stands on the right bank of the Oka River in Rybnovsky District, Ryazan Oblast, 25 km north of Ryazan. Its brick buildings include a 1901 bell tower by architect I. S. Tsekhansky, the two-level St. John the Theologian Cathedral (1689, rebuilt 1861), and the Dormition Cathedral (1868–1870).

The monastery was founded in the late 12th century by Greek monks who arrived from Constantinople carrying a Byzantine icon of Saint John. After surviving raids and periods of neglect across the following centuries, it was closed during the Soviet era and later reopened as an active religious community.

The monastery is dedicated to Saint John the Theologian, and visitors today can watch monks go about their daily routines within the compound. The rhythm of prayer, work, and silence gives the place a lived-in feeling that sets it apart from purely ceremonial sites.

The grounds are easy to walk through, with flat paths linking the main buildings along the riverbank. Visitors are expected to dress modestly, and it is worth arriving outside of service hours to move around freely without disturbing the monastic community.

Near the monastery stands a spring that Orthodox believers consider healing, with a bathing pool open all year; a new five-domed chapel is being built beside it. The monastery also has a filial metochion in Ryazan. The main shrine, a Byzantine icon of Saint John the Theologian, vanished around the 1930 closure and its whereabouts remain unknown.
