Port of Piraeus Zea and Munichia. In 493 BC, Themistocles initiated the fortifications of Piraeus and later advised the Athenians to take advantage of its natural harbours' strategic potential. In 483 BC, the Athenian fleet left the older harbour of Phaleron and it was transferred to Piraeus, distinguishing itself at the battle of Salamis between the Greek city-states and the Persians in 480 BC. In the following years Themistocles initiated the construction of the port and created the ship sheds ("neosoikoi"), while the Themistoclean Walls were completed in 471 BC, turning Piraeus into a great military and commercial harbour, which served as the
Port of Redwood City International Airport and Palo Alto Airport; in contrast, wind speeds at the Port were found to be approximately half the levels of San Francisco Airport. This result is not surprising since Conomos observed that the wind speeds in Northern San Mateo County are high due to the San Bruno Gap in the Santa Cruz Mountains. The Port of Redwood City has more than one lineal mile of public access along Redwood Creek, including walkways, viewing areas and picnic areas. The Port provides a venue for a number of public events and festivals, including visits by historic ships and sailing vessels.
