Moreover in the basement of Agia Triada church, visitors can see remains from the ancient town's buildings. Respectively, at Gouva of Vavoulas' district there are remains of the central gate of the ancient Walls of Piraeus, which are also seen in the Piraeus' beach. In Zea's Harbour and in the naval yard at Kantharos there are "neoniskoi", ancient deckhouses, found while after excavations at Pasalimani the famous ambry of the ancient Greek architect Filonas was found and a part of it is nowadays kept at a underground building of Ypsilantis str.

Karaiskaki Stadium district has been obviously influenced by the athletic history of the area and Olympiakos CFP. Visitors should not miss visiting the Archaeological and the Naval Museums of Piraeus.
