The ruins of the Roman forum of Thessaloniki were only discovered in the early 1960-ies. The remains of structures and unique ancient artifacts found in the excavations have yielded invaluable information about the history and culture of ancient Thessaloniki.

The forum covers an area of about 2 hectares and consisted of a complex of buildings that housed various government agencies (including the Mint and the city archive), public baths, shops, craft shops, Odeon, etc. because Of the natural slope of the ground surface on the South side, the forum had a two-tier structure (the so-called Upper and lower Agora).
