This is all that’s left of the sanctuary of Asklepios ... at one time, circa 400 BCE, there was a circular structure here where the rites of worship were performed ... the main hall was called the Abaton ... the sick and injured pilgrims would make a sacrifice, participate in a ceremony and then be left to have a healing sleep. There are several inscriptions left by people who were cured by the divine powers of Asklepios and his priests.
