The city of Lalibela in Ethiopia is known as a city of pilgrimage. Lalibela boasts 11 monolithic, rock-cut churches, each of which is fascinating to explore. Most residents are Egyptian Orthodox Christian, and most of the churches were constructed in the 12th and 13th centuries. If you only have time for a tour of one church in Lalibela, make it Bet Giyorgis, which is shaped like a cross and carved entirely from rock in a spectacular fashion.
