Cheremenetsky Monastery, Orthodox monastery in Cheremenets, Russia

Cheremenetsky Monastery is a male Orthodox monastery on a peninsula of Lake Cheremenets in the Luga District of Leningrad Oblast. Its white limestone St. John the Theologian Cathedral, built in the 16th century, has five domes and a tall octagonal bell tower above the porch; beside it stands the small stone Church of the Transfiguration, built in 1707.

The first written record of the monastery dates from 1497–1498, though excavations suggest it was founded earlier. A legend attributes its foundation to Ivan III after a peasant named Mokiy found a wonder-working icon of Saint John in 1478. In 1581 Polish-Lithuanian troops of Stephen Báthory burned the monastery, killed or captured the monks, and left only the hieromonk Zakheus and two elders. It was later restored and reopened in 1997.

The monastery's patronal feast is celebrated on 21 May, the day the wonder-working icon of Saint John the Theologian was carried here in 1999 from the Kazan Cathedral in Luga. According to local tradition, the icon first appeared in 1478 to a peasant named Mokiy from the village of Rusynya, prompting Ivan III to order the monastery's foundation.

The monastery sits on an island, so reaching it requires taking a boat, and visitors should plan their journey accounting for water conditions and timing. The site welcomes guests year-round, though checking conditions in advance is wise.

The icon of Saint John the Theologian now kept here came on 21 May 1999, the monastery's patronal feast, from the Kazan Cathedral in Luga. It was not a restoration return: the monastery had been reopened in 1997, and in 2000 it received the former metochion of the Alexander Nevsky Lavra in Saint Petersburg.
