(This article is about monastery in Ethiopia. For monastery in Eritrea of the same name, see Debre Libanos (Eritrea).) Debre Libanos (Amharic: ደብረ ሊባኖስ) is an Ethiopian Orthodox Tewahedo monastery in Ethiopia, lying northwest of Addis Ababa in the North Shewa Zone of the Oromia Region. It was founded in 1284 by Saint Tekle Haymanot as Debre Atsbo and was renamed as Debre Libanos in the 15th century. He meditated in a cave above the current monastery for 29 years. The monastery's chief abbot, called the Ichege, was the second most powerful official in the Ethiopian Church after the Abuna.
