Lalibela is the site of a spectacular complex of 11 rock-hewn Christian churches in mountainous north-central Ethiopia. The churches are of two types: shrinelike grottoes, of which there are four, carved into natural cavities in the mountain slope, and seven monolithic freestanding structures, the foundations of which descend deep into the rock plateau. The freestanding churches, which are still used for worship, are built on a cruciform plan. Three equilateral crosses, carved one inside the other, decorate the roofs, which are level with the plateau. The church interiors were originally covered with mural paintings of scenes from the life of Christ, few of which survive.
