Piraeus is the harbor of both ancient and modern Athens. Piraeus (Greek, Peiraieus), also called Port Draco, was planned by Themistocles and laid out by Hippodamus of Miletus, and built in the glorious days of Pericles. This ruler and Cimon before him built the three "long walls" that connected Athens with its port (5 miles to the south-west), and so ensured a free and safe passage from one to the other at all times. It was both a war harbor and a commercial port, many foreigners living within its walls. Its arsenal (built 347–323 BC) and fortifications were destroyed by Sulla in 86 BC, and from that time the town sank into decay.
