The unpretentious, single-story white structure gives no hint from the outside of the treasures within. A superb collection of artifacts from Neolithic times; sculptures from the Archaic, classical, and Roman eras; and remains from the Archaic temple at Thermi all reside under this roof. Objects discovered during construction of the Egnatia and Thessaloniki–Skopje highways were added in 2005 to the collection, which is displayed in eight galleries. "Thessaloniki, the
Metropolis of Macedonia" traces the city's history through artifacts and a multimedia collection. "Towards the Birth of Cities" offers remains from settlements from Kastoria to Mt. Athos that date to as early as the Iron Age.
