The settlement of Zagora is at the naturally fortified tableland of a remote peninsula in the western coast of the island. It s view allowed the inhabitants to control the sea from Attica to the islands and M. Asia. The constant excavating researches that took place by professor Alexandros Kampitoglou (1965-1972), reveal a big section of a town from the geometrical period. Life in this settlement started the 10th century, with a prime period the second half of the 8th cent., in whose end life stopped abruptly. Ruins of the walls, the private houses and a sanctuary with a temple were found. The wall was built lengthwise of the peninsula s neck and protected the town from the earths side. One could enter the settlement from a big gate, reinforced with ramparts and it was built at the S.W. side of the wall. Schist and gray marble, that were in abundance in the island, composed mainly the construction material. The houses usually composed of a big rectangular space, with a fireside in the center, a continual storing-up place with stony benches lengthwise of the walls for supporting the large casks and a stable with yard which led to the road. In the middle of the settlement the remainders of a sanctuary whose founding refers to the 8th century b.C. were excavated. This was still open until the end of the 5th cent. b.C. even though the settlement had been abandoned 3 centuries ago.
One more geometric settlement was discovered by the archaeologist Christina Televantou in 1981 at Ipsili in the region of Aprovatou in the center of the western coast of the island and in almost 15 km distance from Zagora.
The settlement was built on a big, rocky hill at the widening of the top where the Acropolis was discovered. The wall which surrounded it follows the morphology of the ground and it often embodies the rocky ground. Buildings similar to those of Zagora were found in Ipsili as well. They are out of the acropolis wall. Almost in the acropolis center, a big temple was found, from the same period of that of Zagora, where Dimitra and her daughter Persefoni were worshipped. The temple is dated from the 6th cent. b.C. and its built on the ruins of another geometrical temple. Excavations at the acropolis area brought to the light a building of the Ipoprotogeomentrical period, geometrical and archaic buildings which are chronologically enrolled in the latest Hellenistic Period. This is an evidence that even if the settlement seemed to have been abandoned in its biggest extent almost in the end of the 8th cent. b.C., in the small area of the acropolis, life continued.
From the Archaic and till the earliest Byzantine period, the center of the island is placed in the area of Palaiopolis, that is at the Western section of the island, in a distance of 5 km from Ipsili and 10 km from Zagora.
The ancient ceramics found, gathered from the area, are dated from the Mycenaistic period. Furthermore, tracks of habitation from the geometrical times are preserved. Some of the important things of the area found are, the Daughter of Copenhagen, one Couros and the group of islands Pigassos and Vellerefontis and are dated from the 16th cent. b.C.. These show that the town started to be in its big prime during the Archaic Times. The building activity in the area, according to the preserved things found till nowadays, started at the beginning of the 5th cent. b.C. and lasted until the Paleochristianic years. The extent of the town is known, as its fortified yard is preserved till nowadays in almost all of its length and height. The center in Palaiopolis-Agora was near the beach. In the eastern side was the port, whose remainders are still visible nowadays, sunk in the sea. Its cemeteries are extended at the slopes outside the town’s walls in E. and W. From the ruins, the numerous sculptures found and the written sources, one can result that the town was very well organized and apart from the Agora, it disposes theatres, fervors, sanctuaries and temples.
