The lay of the land is religion writ large in Lalibela, one of the greatest historical and religious sites in the Christian world. Rock-hewn churches carved from thick bedrock meld architecture and landscape in striking examples of creativity and ingenuity that far surpass Petra in extent. The free standing, subterranean, cross-shaped tower of Bet Giyorgis is particularly mind-blowing, but walking through the cool tunnels connecting some of the other smooth-hewn buildings is just as revelatory an experience; human achievement is perhaps never so grand as when it bridges the natural and divine. So astounding is Lalibela many believe it the work of angels and in some churches hermits and monks live in tiny wall caverns, attempting to be closer to their maker. A site of pilgrimage, as it has been for centuries, Lalibela will not disappoint the faithful and faithless alike.
