Drive 110 km north from Addis over passing Mount Entotot and Embark on a day trip 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's chief abbot, called the Ichege, was the second most powerful official in the Ethiopian Church after the Abuna. 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 neighboring 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. The cave where the saint lived is in the nearby cliffs, which one travel guide describes as a five-minute walk away. This cave contains a spring, whose water is considered holy and is the object of pilgrimages.
