During the Peloponnesian War, Piraeus suffered its first setback. In the second year of the war, the first cases of the Athens plague were recorded in Piraeus. In 404 BC, the Spartan fleet under Lysander blockaded Piraeus and subsequently, Athens surrendered to the Spartans, putting an end to the Delian League and the war itself. After the reinstatement of democracy, Conon rebuilt the walls in 393 BC, founded the temple of Aphrodite Euploia and the sanctuary of Zeus Sotiros and Athena, and built the famous Skeuotheke (arsenal) of Philon, the ruins of which have been discovered at Zea harbour. The reconstruction of Piraeus went on during the period of Alexander the Great, but this revival of the town was quashed by Roman Lucius Cornelius Sulla, who captured and totally destroyed Piraeus in 86 BC. The destruction was completed in 395 AD by the Goths under Alaric I. Piraeus was led to a long period of decline which lasted for fifteen centuries. During the Byzantine period the harbor of Piraeus was occasionally used for the Byzantine fleet, but it was very far from the capital city of Constantinople.
