Lalibela
Hidden for centuries in the remote highlands, about 700 kilometers north of Addis Ababa, the magnificent rock-hewn churches of Lalibela are not to be missed by today’s visitor. This group of eleven monolithic and semi-monolithic structures was carved directly into the stone of the mountainside at least 800 years ago. With the largest monolithic church in the world; a maze of passageways and tunnels; intricately carved reliefs; and fabulous examples of icon paintings; the Lalibela churches were built by carving a massive rectangular trench around a solid stone block. This solid block was then hollowed out, leaving interior columns, windows, reliefs, etc. Other churches were carved in a similar fashion but leaving either one side or the roof attached to the surrounding stone. Not only the craftsmanship but also the sheer size of the churches is stunning. Medhane Alem, the largest, sits on 800 square meters and St. George is 15 meters deep.
