Lalibela, revered as a saint, is said to have seen Jerusalem in a vision, and then attempted to build a new Jerusalem as his capital in response to the capture of old Jerusalem by Muslims in 1187. Each church was carved from a single piece of rock to symbolize spirituality and humility. Christian faith inspires many features with Biblical names – even Lalibela's river is known as the River Jordan. Lalibela remained the capital of Ethiopia from the late 12th into the 13th century.
The first European to see these churches was the Portuguese explorer Pêro da Covilhã (1460–1526). Portuguese priest Francisco Álvares (1465–1540), accompanied the Portuguese Ambassador on his visit to Dawit II in the 1520s. He describes the unique church structures as follows: "I weary of writing more about these buildings, because it seems to me that I shall not be believed if I write more... I swear by God, in Whose power I am, that all I have written is the truth[.]"
Although Ramuso included plans of several of these churches in his 1550 printing of Álvares' book, who supplied the drawings remains a mystery. The next reported European visitor to Lalibela was Miguel de Castanhoso, who served as a soldier under Cristóvão da Gama and left Ethiopia in 1544. After de Castanhoso, more than 300 years passed until the next European, Gerhard Rohlfs, visited Lalibela some time between 1865 and 1870.
