In the area of Vathis, at a mound near the port, next to the church of Saint Irene, there are the remains of a tower of the Hellenistic period, as well as of the corresponding surrounding. In addition, in the area of Vathis, at the mound Kastella, in “Stimenia”, there are remains of an acropolis, which is known as the Acropolis of Kastella. As far as the place name Stimenia is concerned, it probably emanates from the word “temenia”, which in Greek means mosques or churches. The remains are characterized as pelasgian and carian. However, the use until the Byzantine times is also probable.
