The Roman Baths in the sea at Katakalou were discovered by G Dionysiou. The importance of the baths in the social life of region is certified by that they have remained in collective memory until our days in the name of region Loutraki. The group is a reflection of public architecture of the time. Chronologically Roman Thermal baths of the late 3rd century AD and reflect the Romans attitude that public baths were not only a place of personal hygiene, but also to meet, walk, exercising and part of the social life of city. The Baths are oriented north west and are visible 42 m length and 0.5 - 4.5 m wide, not including the area that is already covered by the sea. From west to east are 7 sections, which have not been subject to excavation. Section 1: mosaic flooring in opus caementicium, section 4: low burning with round earthen pessary (pilae) survive above of which is the flooring of pottery plates (suspensuae). Section 5: this has traces of low burn and can be considered as the praefurnium while it is possible that the common reservoir (alvus) of the Baths is here.

In the southwestern side of Skopelos from Skiathos and Evia, in the imposing and naturally fortified hill of Paleokastro is the one of the three ancient cities of island. Here Halkidis seamen and tradesmen found ancient Selinounta, the ancient name did not survive, but is known from the descriptions by the high priest of the city of Ikesiou and the Emperor Adriano, 2nd century AD.

The area was inhabited from the Iron Age, 8th century BC until the Later Antiquity of 4th century AD. Then the criteria with which an area was chosen for habitation was very different from today. The choice depended their well-being; a high point that did not have fog, did not suffer from the heat and had low marshes, access to drinkable water and in the countryside that could produce food, ease of movement to the city, defendable, convenient and with natural beauty - the city of Paleokastro fulfilled these criteria.

During the Classical years the citadel was fortified with walls that are visible today. The walls were built on steep cliffs by the sea, with strong towers that jutted out, wide enough for two armed men to walk side by side. The streets were beside the gates and the harbour was exposed to the southern and southwesterly winds. The city stretched out on the plain with squares, buildings, temples and the cemetery, where their loved ones were cremated, was outside the city walls. There is the possibility that earthquakes have transformed the region and parts have sunk into the sea.

During the Roman period the city bustled with life, a quiet cosmopolitan rich Loutropoli and located on the Paleokastro hill towards the southeast, parallel to the coastline to the low sloping hills that close amphitheatrically towards the sea at Katakalou. The multistorey buildings were built in Roman style. As all the Roman coastal provincial cities that combined the trade of Paxromana with the enjoyment of nature and public areas that gave insight to Roman daily life.

There were: wells, aqueduct, covered streets, organised commercial centre, areas of small industry, temples with statues and public baths. Other evidence of the same period were the offerings and statues implying that social life was completely included in the Roman order of things. The sarcophaguses that were found in the Selinounta and in ancient Peparitho are luxurious products of imported from the ancient city of Assos of Asia Minor and belonged to the wealthy of region. The city participated actively in the organised marine commercial network of the Roman Empire from the N Aegean to the coasts of Lebanon, Egypt, Adriatic Sea and Sicily with goods that were addressed to the urban population.

Farmers and livestock breeders lived periodically on the mountainous plateau of Glossa that was the rural region of the ancient city Selinountas suitable for growing cereals, legumes, vines and olives. These rural installations, simple huts and organised farms with fortified rural cottages date to the Classical and Hellenic periods with continued human presence from the Roman and medieval years onwards. These developed in the Greek countryside during the 4th century BC and relate to the agriculture, trade, quarries and mines, the control of roads on land and the sea. These can be found in all ancient Hellenic areas and islands, from the Black Sea to the western Mediterranean.

Organised ranches with fortified rural cottages were roughly 6 km from ancient Selinounta and were within sight of each other roughly 600 m apart on different levels. In the centre was the largest rural cottage with a network of paths radiating from it that connected the fortified rural cottages. The largest source of water was in Livadaki and the cape of Limonari that had a gradual gradient to the sea.

Fortified rural cottages were located in: Mayraga'nj, Elliniko, Sentoukia, Prionas, Agios Georgios, Agios Taxiarhis, Koniari Ridge and Mavraki, while individual installations were found in: Livadaki, Limonari and Agii Apostles. The rural structures of those who lived and are living in Glossa and surrounding areas have remained much the same from antiquity to the present day in the light of tourism and globalisation.
