Jaanilinna Jumalaema Uinumise kirik, Orthodox church building in Ivangorod, Russia

The Church of the Dormition is a stone parish church built in 1507–1509 inside Ivangorod Fortress, probably by Mark Grek. It consists of a northern church building and a southern wing that became the separate Church of the Protection of the Mother of God in 1757. The church kept the Hodegetria icon of the Mother of God, which tradition says survived the 1558 Narva fire undamaged.

A stone church was built in 1507–1509 inside Ivangorod Fortress, probably by Mark the Greek. Under Swedish rule it was reconsecrated as a Lutheran garrison church; after Russian troops took Narva and Ivangorod in 1704 it was closed. Empress Elizabeth ordered its restoration for Orthodox worship in 1744, and in 1757 its Pokrov chapel became a separate Church of the Intercession. Damaged in 1944, it was restored in 1976–1985 and returned to the Russian Orthodox Church in 1991.

The church keeps the Hodegetria icon of the Mother of God, which tradition holds survived the 1558 Narva fire undamaged. Until 1940 the parish served Ivangorod and nearby villages such as Popovka, Dolgaya Niva and Komarovka. Since 2010 a side chapel honours the new martyr Alexander Volkov.

The church stands inside Ivangorod Fortress on the Russian side of the Narva river, facing Narva's Hermann Castle across the water. It is an active Orthodox parish, so services resume there after decades of other use. Visitors reach it on foot within the fortress grounds; modest dress and quiet conduct suit the setting.

For several years in the late 20th century, the building served as a concert hall rather than a place of worship. This unexpected transformation shows how the structure adapted to different needs before returning to its religious purpose.
