This is the sole architectural material that was used in the structure. It has been dated to the late 12th or early 13th century AD, and thought to have been constructed during the reign of King Gebre Mesqel Lalibela, of the late Zagwe dynasty.[1] It is among the best known and last built of the eleven churches in the Lalibela area, and has been referred to as the "Eighth Wonder of the World".[2] Lalibela, King of Ethiopia, sought to recreate Jerusalem, and structured the churches' landscape and religious sites in such a way as to achieve such a feat. I like the concept, first you have to really get up close to notice that it's there, and then its difficult to invade, as in "home invasion", of course it's not immune to attack helicopters and RPGs, but you get the idea https://upload.wikimedia.org/wikipedia/commons/thumb/a/a4/Bete_Giyorgis_01.jpg/800px-Bete_Giyorgis_01.jpg
