In a city like Athens it was inevitable that the excavations for the Metro should unearth a huge amount of archaeological finds. In the area surrounding Syntagma Square several strata of the city's past came to light, from the Hypomycenaean to the Byzantine era. Part of these finds were transferred to the University Campus, where they are displayed in three tiers, preserving their relative position in situ.

Τhe Archaeological Park is an annex of the Archaeoloogy Department's Museum of Archaeology and History of Art. Many of the exhibits are visible to passers-by and it can be visited by arrangement. The Department of Archaeology has organized a programme of guided visits for schools.
