This is the entrance to a tiny 13th Century Rock Church in Tigray, called Abuna Yemata Guh. And yes, that’s a narrow ledge you have to walk along, with a 200 metre vertical drop to your left, at the end of a terrifying ascent up the side of a cliff to get there.

The dangerous climb is rewarded with an extraordinary church, carved into the rock, with glorious paintings.
