A child prays in one of the churches of Lalibela. In the twelfth century, Prince Lalibela was built north of the current Ethiopian territory a dozen churches carved in stone. All connected by underground passages that pierce the volcanic rocks of the parched and aisladísima population that bears the name of the monarch, stands as an unexpected and wonderful miracle of Christianity in this unknown corner of the African continent. Indeed, the misty mountains of central Ethiopia hiding a big secret. Its villages, nearly 3000 feet high, are inaccessible during the rainy season and dry the rest of the year. This, of course, contributed to their isolation for centuries. So hard to believe our eyes when the ground suddenly collapses, carved by skilled hands, and appear the lines of a cross-shaped temple.
