Biete Abba Libanos is a rock-hewn monastery located in the northern highlands of Ethiopia, near the town of Lalibela. It is one of 11 monolithic churches that were carved out of solid rock in the 12th century, during the reign of King Lalibela.

The monastery is named after Abba Libanos, who was one of the nine saints who came to Ethiopia in the 5th century to spread Christianity. It is situated at an elevation of 3,500 meters above sea level and is one of the most remote and difficult to reach of all the churches in Lalibela.

Biete Abba Libanos is carved directly into the rocky cliff face and is accessed via a narrow tunnel. The church has a simple rectangular floor plan and features numerous pillars and arches, as well as several small chapels and crypts. The interior is decorated with colorful frescoes and intricate carvings, including depictions of saints, angels, and biblical scenes.

The monastery is still in use today and is an important site of pilgrimage for Ethiopian Orthodox Christians. Visitors can access the church by following a steep, winding path up the cliff face, which offers stunning views of the surrounding countryside. Biete Abba Libanos is a UNESCO World Heritage site and is considered one of the most impressive examples of rock-hewn architecture in the world.
