This is a door of a small chapel, carved out of the rock in Lalibela in the Ethiopian Highlands. The door leads to the courtyard of Biete Mariam (Mary’s House), one of the eleven monolithic churches in the small town.
It is said that King Lalibela wanted to create an Ethiopian version of New Jerusalem, compete with the River Jordan running through it, more than 700 years ago. He was helped by angels, who did a lot of the work at night.
