Mavrovo, Macedonia

St Nicholas Church (Macedonian: Св. Никола Летен) is an abandoned church in Mavrovo, North Macedonia which is submerged in Mavrovo Lake. Built in 1850 with icons painted by Dicho Zograf, the church served as the main village church of Mavrovo. With the construction of the hydroelectric power station in Mavrovo and the artificial Mavrovo Lake, the church got submerged under water. During summer periods of drought, the church is accessible through land.

Despite being submerged in water, the church has preserved its initial construction. Its bell tower still exists, although the church's interior is destroyed and the roof has completely caved in. The church was included in the list of abandoned churches published in 2013 by The Huffington Post.
