The most famous of the edifices is the cross-shaped Church of St. George. Tradition credits its construction to the Zagwe dynasty King Gebre Mesqel Lalibela, who was a devout Orthodox Tewahedo Christian. The medieval monolithic churches of this 12th-century 'New Jerusalem' are situated in a mountainous region in the heart of Ethiopia near a traditional village. Lalibela is an important center of Ethiopian Christianity, and even today is a place of pilgrimage and devotion. Lalibela is one of the world's heritage sites registered by UNESCO.
