Lalibela is located in the North Wollo Zone of the Amhara Region, at roughly 2,500 meters (8,200 ft) above sea level. It is the main town in Lasta woreda, which was formerly part of Bugna woreda. The Rock-Hewn Churches were declared a World Heritage site in 1978. Lalibela is famous for its rock-cut monolithic churches. The whole of Lalibela is a large antiquity of the medieval and post-medieval civilization of Ethiopia. Lalibela is one of Ethiopia’s holiest cities, second only to Axum, and a center of pilgrimage. Unlike Axum, the population of Lalibela is almost completely Ethiopian Orthodox Christian.
