The extension of Metro Line 3 to Piraeus was an important opportunity to conduct an extensive
archaeological excavation, the largest in extent and one of the largest in depth ever carried out in Piraeus.
More than 10,000 archaeological findings have come to light.
The most important of the findings are considered to be the pebbled floors of the Alexandrian era, found in the Deligiannis shaft, which
are exhibited under glass flooring at the “Municipal Theatre” station, connecting the present with the past of Piraeus.
This station is a model of the composition of the ancients with the Metro, since it hosts a permanent exhibition, which
includes the original courtyard of an ancient house with a pebbled floor, as well as the visual representation of the fabric of ancient and modern Piraeus, in a highly aesthetic space.
