Built over a junction of the subterranean aqueduct of Peisistratus (early fifth century BC), which brought drinking water from the foot of Mount Hymettus to the city of Athens, the outdoor exhibition area at Syntagma Square houses the finds from two grave enclosures of the fourth century BC. These finds represent a fraction of the important antiquities discovered during the excavation of the Syntagma Metro Station, which testify to this area's continuous occupation from the eleventh century BC until the nineteenth century AD.


Here, two contiguous grave enclosures were revealed during excavations by the Third Ephorate of Prehistoric and Classical Antiquities on Amalias Avenue in 1992. They were part of a cemetery, which developed along the north side of the road leading towards the Mesogeia, and each of them was surrounded by a cluster of pillaged tombs.


The tombs were conserved and sheltered; sign-posts with texts, drawings, and photographs complete the display.
