This small wooden Orthodox church with a shingled roof, situated in the Kinský Gardens, is a typical folk wooden log building from Subcarpathian Russia of the 18th century, today Zakarpatí in Ukraine. It was moved to Prague from Medvedovce near Mukachevo, to where it was moved from Velké Lúčky in 1793, and was built again in Prague in 1929. The church is part of the collection of the Ethnographic Museum.
