Walking along the fortification, the impressive Gymnasium appears at some point; it is wonderfully preserved until today. The Gymnasium and the Stadium constitute a unity since they belong to a unified architectural plan. A space with three Doric stoas (colonnades) is where adolescents exercised. Between the colonnades is the area of the Palaestra (wrestling arena) a peristyle atrium of the Doric style of 30 meters, where they warmed up and fought.
Artefacts of the Hellenistic period were found here. Exercise was part of a broader education that, moreover, had a political character. A kind of school that shaped citizens. The adolescents were taught the secrets of the community. They studied for three years following the stages of initiation during their teenage years: first they became warriors, then men and next, worthy citizens.
In the Gymnasium they studied and were recorded in the male registry according to the tribe they belong to. Vast lists of adolescents in columns name the future citizens to be. Something like a class list. The teenagers that would be lucky enough to follow this schooling were those of aristocratic origin and free citizens; freed slaves would serve them. "Metics" (foreigners) and slaves played a secondary role. On its columns marks of their engraved names and of the games "pessi" and tabula they played at recess are evident.
The next monument is burial building 2 – that is how it was named during excavation. It has a double chamber and a colonnade, probably a mausoleum and one of the most important burial monuments in Greece. Its chambers are of great dimensions: 4.70 x 5.40 m and it has a Doric colonnade (14.50 m length x 3.80 m width) bearing ten Doric columns.
Also, marble sarcophagi and fragments. In the colonnade, four pits with remnants of cremated infants were unearthed, such a macabre sight. Grave goods and pottery, lamps with relief decoration and carbonized fruit: pomegranate, wheat, raisins.
A strange burial custom, firstly because the infants were cremated and secondly, because their remains were kept outside, at the colonnade, in other words not inside the burial chambers. A burial monument commemorates deceased infants through the ashes and indeed next to the Gymnasium. What glorified death, of which important family were they members to earn such a conspicuous position? Nonetheless, the same chambers became areas of burial and residence during the early years of Christianity. Thus, the use of the monuments by the Christian inhabitants, probably answers the question.
