The Roman Forum of Thessaloniki, also known as the Ancient Agora, served as the administrative, social, and commercial heart of the city during the Roman period. Located in the center of modern Thessaloniki, the complex was constructed in the late 1st or early 2nd century CE, replacing an earlier Hellenistic agora. It features a large rectangular plaza surrounded by two-story stoas, a small odeon (theater) used for public performances and council meetings, and an extensive network of underground vaulted passages known as the Cryptoporticus.
Following the decline of the Roman Empire, the site underwent various transformations, including the construction of Byzantine-era structures over the ruins. Excavations in the 1960s revealed the extent of the complex, which had been largely obscured by centuries of urban development. Today, the site serves as an open-air archaeological park, providing a rare glimpse into the urban planning and civic life of a major Roman provincial capital.
