 The Lecythus fort, next to the harbour, was rebuilt during the Byzantine era, along with cisterns and a small early Christian temple.Parts of the ancient city, including most of the "Proasteion", the agora and the ancient harbour are nowadays sunk 35m from the coast, as the underwater surveys have proven, since a large 60m long and 2m wide foundation was found, probably the ancient seawall.The whole area between this foundation and the modern coastline is scattered with stoneworks and large amounts of pottery, which indicate the presence of large buildings.
