 In the 12th century religious <unk> started inhabiting the caves on Mount Carmel , and in the 13th century they formed a new Catholic monastic order , the <unk> . Under Muslim rule , the church which they had built on Mount Carmel was turned into a mosque , later becoming a hospital . In the 19th century , it was restored as a <unk> monastery , the Stella Maris Monastery . The altar of the church as we see it today , stands over a cave associated with Prophet Elijah .
