The African Royals[]


Heirs to earlier ascetic traditions, East African monasteries were often situated in remote locations such as the flat-topped mountains, or amba, occurring in the region. A prominent example of these is Debre Damo in Tigray, but there was also another type, the rock-hewn church, exemplified in Lalibela. As European contact with East African societies increased, European architectural techniques also influenced African churches.
