It is the most important attraction, located on the south side of the bay, in the direction of Costa. Archaeological excavations were conducted periodically since the early 20th century, most of which were conducted by Americans in 1962. During the excavations important findings were brought to light, such as ancient temples, a stadium and many brick and clay utilitarian objects. The remains of the ancient walled port and sunken colonnade of the temple of Apollo are still visible in the shallows of the water.
