Church of St. Nicholas of the Roof, Byzantine church in Kakopetria, Cyprus.

The Church of St. Nicholas of the Roof (Agios Nikolaos tis Stegis) is a domed cross-in-square Byzantine church begun in the early 11th century, about five kilometres from Kakopetria beside a stream in the Karyotis valley. Its name comes from the second, steep-pitched timber roof with flat tiles added over the nave and narthex in the early 12th century, when the narthex itself was built with a calotte and two transverse arches.

The building was constructed in the 11th century as a monastery church and received wall paintings over six centuries of artistic development. The layers of these artworks show different phases of religious and artistic expression that accumulated in this space.

The name "tis Stegis" comes from the second timber roof of flat tiles added over the nave and narthex, giving the church its "of the Roof" nickname. Inside, a 12th-century over-life-size St. Nicholas, the patron, is shown with Christ handing him a Gospel and Mary an omophorion, a monk praying below. A 14th-century Nativity shows Mary as Galaktotrophousa nursing the child, with goats climbing the hills and a young man playing a flute.

The church stands about five kilometres outside Kakopetria, beside a stream in the Karyotis valley, and is reached on foot from the road. The interior is dim, so bring a torch to read the frescoes. The narthex added in the early 12th century is entered before the nave.

The church is not documented in surviving texts until the 13th century, although construction began in the early 11th century. Its second timber roof with flat tiles, added later, gave it the name "of the Roof" (tis Stegis) and hides a normal cross-in-square church with a dome beneath.
