Voskopoje / Moschopolis Albania
During the 17th and 18th centuries, Voskopoje, with 26 churches, was one of the most important Christian centers in the Ottoman-controlled Balkans. Saint Nicholas, built in 1721, is the largest of the five that remain. Frescos by the master Onufri survived, though the church was used for storage during the Communist era. Chalices and chasubles were secreted in the wall for safe-keeping during that time. The frescos are threatened by water seepage. The five churches were listed on the 100 most endangered sites of the World Monuments Watch in 2002.
