(CNN)Archeologists have unearthed the remains of a town from an influential but little-known ancient civilization in East Africa that sheds light on the origins of Christianity in Ethiopia.
The buried settlement, which contains one of the oldest churches in sub-Saharan Africa, was inhabited for some 1,400 years before vanishing into the dusty highlands of northern Ethiopia around AD 650.
Called Beta Samati, it was part of the Empire or Kingdom of Aksum, but prior to its discovery archeologists thought the area had been abandoned when the empire's ruling class set up its capital elsewhere.
