Pertominsky Transfiguration monastery, Russian Orthodox monastery in Pertominsk, Russia.

The Pertominsky Transfiguration Monastery stands on Krasny Rog cape on the east shore of Unskaya Bay, about 125 km north of Arkhangelsk. Its surviving complex from the 18th to early 20th century consists of two two-storey buildings and four corner towers of the enclosure wall; all churches were demolished in 1929.

The monastery traces its origin to 1561, when the drowned Solovetsky monks Vassian and Iona were buried on the cape; a chapel was built over their graves in 1599. The community formed around the hermit Ioasaf in 1617, the accepted founding year. In 1694 Peter I prayed here after surviving a storm and set up a cross on the shore. Closed in 1920, the site held one of the first northern special-purpose camps.

The monastery is named after Saints Vassian and Jonah, Solovetsky monks who drowned in 1561 and were buried at Cape Krasny Rog. Pilgrims began visiting after a chapel was built over their graves in 1599. In 1694 Peter I placed a cross at the site of his rescue from a storm, and a copy still stands on the coast.

The monastery stands on the Krasny Rog cape on the east shore of Unskaya Bay, about 125 km north of Arkhangelsk, in the village of Pertominsk. The surviving complex of two two-storey buildings and four corner towers of the wall dates from the 18th to early 20th century. A copy of Peter I's cross stands nearby on the coast.

A cross near the monastery was reportedly established by Peter the Great himself, creating a direct historical connection between this remote religious site and Russian imperial history that continues to attract scholars and pilgrims.
