Palaio Faliro (Greek: Παλαιό Φάληρο, pronounced [paleˈo ˈfaliro] ⓘ; Katharevousa: Palaion Faliron, Παλαιόν Φάληρον, meaning "Old Phalerum") is a town on the Saronic Gulf coast and a municipality in the southern part of the Athens agglomeration, Greece.

The neighbourhoods of Palaio Faliro are Amfithea, Batis, Edem, Panagitsa, Floisvos, Palmyra, Pikrodafni, Agia Varvara and Kopsachila.

[8] The site of the ancient town appears to be the area and headland around the church of St. George,[9][10] with the harbour to the west in the open roadstead.

Remains of conglomerate blocks have been found crossing the heights of Old Phaleron to the sea and these are likely to be part of the Phaleric Wall recorded by Thucydides.

[12] In the reign of the emperor Justinian, Stephanus of Byzantium, in his geographical dictionary Ethnica, records Phaleron as a deme and port of Attica.

Throughout the period of Frankish rule, which followed the Roman-Byzantine empire, Athens was confined within the late Roman walls, and the area beyond became a wasteland.

In 1674 the English Consul in Athens, Jean Giraud, called this location "Three Towers" or Tripyrgi, a place-name that was retained into the 19th century.

Greek troops landed around the Three Towers area and advanced on the Acropolis but the expedition ended in disaster and the fortress capitulated in June.

Before 1920 old Phaleron was a small seaside village where the houses were few and between which there were long stretches of wheat, barley and oats as well as many vineyards.

[16] In the western 'Delta' area a sea plane airport was started in August 1926, with the first international route Brindisi - Faliro - Istanbul.

Many Greeks from Istanbul (Constantinople) came to live in Palaio Faliro, especially after 1974, and now form a very active and prominent community.

[17] During the 2000s, especially during the Summer Olympics 2004, Palaio Faliro saw major improvements in its infrastructure, such as the establishment of the Tram Line 3 that serves the southern coastal area of Athens.

In 1925 Palaio Faliro was established as a local government Community (i.e. civil parish or township) with the Presidential Decree 27/8/1925.

Other landmarks include: The oldest church of Palaio Faliro is the chapel of St. George in Xirotagaro, next to the Museum of Naval Tradition.
