Debre Libanos

Its one of the ancient and historical monastery in Ethiopia, Which is lying on northwest of Addis Ababa. The monastery was founded in the 13th century by Saint Tekle Haymanot, according to tradition; he meditated in a cave for 29 years. The monastery complex sits on a terrace between a cliff and the gorge of one of the tributaries of the Abbay River. None of the original buildings of Debre Libanos survive, although David Buxton suspected "there are interesting things still to be found among the neighbouring cliffs." Current buildings include the church over Tekle Haymanot's tomb, which Emperor Haile Selassie ordered constructed in 1961; a slightly older Church of the Cross, where Buxton was told a fragment of the True Cross is preserved; and five religious schools
