Biete Abba Libanos — the House of Abbot Libanos — is unusual within the Lalibela complex in that it is not fully free-standing: the rear wall and the ceiling merge into the cliff face behind it. This semi-monolithic construction gives it a different feel from the fully isolated Biete Giorgis or Biete Medhane Alem, and it is classified separately as a cave church rather than a true monolith. The facade is still carved with considerable care, featuring blind windows and decorative Axumite friezes.
The church is dedicated to Abba Libanos, a fifth-century monk who brought Christianity to the Lasta region — making it one of the more historically resonant dedications in the complex. Inside, the proportions are modest but well-finished, and the altar area retains some early painted decoration. It sits between the northern and southeastern groups and can be reached through a passage cut in the rock. The evening light, when it catches the carved facade, is particularly good here.
