In the western part of Eresou beach, in the Afentelli area, are the ruins of another early Christian church, of the same style as the basilica of St. Andrea. It is a three-aisled basilica of the 5th century, the floor of which is decorated with representations of peacocks from mosaics.
The bases of the columns and the capitals found scattered in the area are of the Ionic style, while of particular importance is the inauguration of the holy table, which is now kept in the archaeological museum. It is a small marble sarcophagus that contained the relics and myrrh of a saint.
