church in lalibela | World Heritage Rock-Hewn Lalibela is a town in northern Ethiopia that is famous for its monolithic rock-cut churches. Lalibela is one of Ethiopia's holiest cities, second only to Aksum, and is a center of pilgrimage for much of the country.
The Ethiopian city of Axum has a series of 7 giant obelisks that date from perhaps 300 BC to 300 AD. They have details carved into them that represent windows and doorways of several storeys. The largest obelisk, now fallen, is in fact “the largest monolith ever made anywhere in the world”. It is 108 feet long, weighs a staggering 500 tons, and represents a thirteen-storey building.
