The Monastery of Saint Thaddeus, known in Persian as Qara Kelisa (Black Church), is one of the most important Armenian Christian monuments in the world and a UNESCO World Heritage Site since 2008. It sits in a remote valley about 20 kilometres south of Maku at 2,200 metres above sea level, reached by a rough road through mountain terrain.
The monastery complex consists of two distinct buildings: the original dark-stone church (the "black" church that gives the site its name, built of local basalt) and a later white marble church added in 1810. The contrast of black and white stone, set against barren mountain landscape, is visually striking and unlike any other church in the region. The interior preserves Armenian inscriptions, carved khachkars (cross-stones), and fragments of ancient decoration.
The annual pilgrimage in late June or early July brings thousands of Armenian Christians to the site for a week of religious celebration and cultural events. If you can time a visit to coincide, the gathering is an extraordinary spectacle in an extraordinary setting.
