The Makra Stoa (Long Stoa) is an archaeological site in the ancient port city of Piraeus, Athens, built during the age of Pericles in the 5th century BC. Also known as the Alphitopolis Stoa, the long colonnaded building stored imported cereals -- mainly barley and wheat -- for distribution to Athens and supply of the Athenian trireme fleet. One side featured an open colonnade while the other contained rectangular shop rooms connected by a 5 m wide service road to the city wall. In 411 BC the Stoa was incorporated into the city fortifications. The fenced ruins remain visible at the corner of Akti Poseidonos and Dimitriou Gounari streets.
