Beneath a large, grass-covered area is the ancient agora. It started to be organized during the 5th century B.C. Amongst uncovered buildings are a hypostyle hall with sides about 32 m long. It was built around 460 B.C. A large building, perhaps a 'palaistra', with porticoes of doric columns, was bordering the southern side of the Agora.
During the Roman times, many of the existing buildings were altered in shape and function, mostly into shops and fountains when, in the 2d and 3d century A.D. a general remodeling of the site took place.

The invasion of the Goths, in 395-396 A.D. accelerated the destruction and the disappearance of the monuments of the Agora.
