The underground cryptoporticus likely served as a storage area for goods traded in the forum.
The Roman Agora was abandoned in the 6th century, after which the space was partially built over by Byzantine housing.
The odeon, which could seat approximately 400 people, was eventually expanded to accommodate gladiator matches.
Construction of the site began during the mid-2nd century AD, likely under the reign of Emperor Hadrian.
The forum's design was part of a larger Roman renewal project to align Thessaloniki's civic layout with other major imperial cities.
The Roman Forum of Thessaloniki, also known as the Ancient Agora, served as the administrative and social hub of the city from the 2nd century AD until the early Byzantine period. The complex features a two-tiered stoa, a central paved square, and an odeon used for theatrical and musical performances. Archaeologists discovered the site accidentally during excavations for a courthouse in the 1960s. Much of the site remained buried under the modern city grid until then, revealing a well-preserved complex that highlights Roman urban planning. Below the main square, a unique cryptoporticus—a covered subterranean passageway—remains accessible. The architecture exhibits strong influences from the Hellenistic period, reflecting the Roman adaptation of earlier Greek public spaces. The site is situated in the city center, surrounded by contemporary urban development.
