The archaeological season of 2011 was located in the agora of the city, in sectors 15 and 16, between the acropolis area and the hill 104. Sector 16, where during the previous seasons a curved structure was uncovered, extending to the west of a large public square, confined in the north by the long Hellenistic portico; whiles the other sector located to the eastern extreme of the portico.
This year’s excavation revealed 5 extensive phases of occupation. Right above the sterile ground, the excavations uncovered layers of ceramic wares (proto-Corinthian cups, Corinthian oenchoes, globular hydrie, monochrome kotyle, and etc.), along with traces of productive activities (burned earth, charcoal, pyramidal and conical loom weights of Corinthian imports, spindle whorls and ceramic coils, related probably to textile industry, metal slag and etc.) and occupation (timber post holes of semicircular cut, decomposed clay remains of wall plasters) activities, all dated to the archaic period (late 7th and beginning of 5th Centuries).
These layers were cut by irregular stone wall foundations of houses and then by east-west road beds. Their associated layer contained material (mainly pottery with painted bands) of the first half of the 5th Century BC, a time which seems to be related to the urban planning of insulae, divided by a network of perpendicular or parallel roads, and the beginning of construction works at the habitation area of the agora. Above these latter structures, other wall lines and road traces were identified, which appear to be of a different orientation (north-south) and building technique (with irregular limestone blocks and baked bricks). The related material dates between the end of the classical and beginning of the Hellenistic periods, suggesting for the transformations of the habitation area at this time. The walls of one of the insulae are cut by the foundations of the semicircular structure, and their fill deposit contains ceramics (mainly black-gloss wares) of the Hellenistic period. The construction of an embankment of the same period, next to this structure, suggests that the agora was re-leveled. In the inner part of the northern side of the apsidal structure, the excavations revealed the stone foundations of the rear wall of the large portico, a building which was constructed at a later time, though within the Hellenistic period. A tomb uncovered above the foundations of the rear portico wall contains funerary artifacts of the 2nd- 3rd Centuries AD, suggesting the devastation or seizure of the monument during the Imperial period. This event also marked the final phase of occupation in this part of the city.
