"The Great Basilica is one of the remains from the Byzantine Period. Designed with pillars and containing three naves and one apse, the structure is 35.5 x 19 meters making it one of the largest basilicas in Karia. Some architectural elements carrying the middle nave and the floor have partially survived. There are many decorated architectural pieces with good workmanship underneath the dense rubble. Reused material can be seen in the building. In a later period, a cistern was built on the northwest corner of the church. The basilica dates back to the 5th and 6th centuries A.D."
