The sanctuary of Asclepios. The entrance (Propylon) to the god of healing, Asclepios (previously incorrectly identified as the sanctuary of Zeus) was on the street to the East. The temple in-antis was built in the ionic order in the late 2nd century BC with decoration based on the older temple of Athena. To the west are the remains of the altar. To the south a fragment of the base of the cult statue of Asclepios, which probably also included his wife Hygieia. There was a portico on the north side. A Byzantine castle was built over the northeast part of the sanctuary in the 13th century.
