The first permanent residents inhabited around the old Athens–Laurium highway that passed through, descending from Northern Greece, mostly Arvanites from Ipiros sent to the Masogean plain at around 1205 a. C. as mercenaries to protect the Duchy of Athens.

The center of the city is located around the Mekedonias Square, northern of Marathonos Avenue, which is a meeting place for all residents and visitors, a true adornment, whereas St. John is the patron saint of Gerakas.

According to Greek historians, Gargitos was a local hero of the region who inhabited Attica after moving from Peloponesse during the Peloponnesian Wars, descending from Asia along with the Lydian Pelops.

At first, it was enclosed geographically within the Athens basin, but due to borders allocation it was partially removed towards the mesogean plain, losing pieces of Patima, Pefka and Stavros from Chalandri and Agia Paraskevi and gaining parts of Balana from Pallini.

Gerakas is surrounded by Vrilissia, Halandri and Agia Paraskevi to the west, Glyka Nera to the south, Pallini and Anthousa to the east and Penteli to the north.

The union takes place at a significant position, as a passage from the great city to the plain delimited by the Attica mountains, reaching the east coast.

And, while the armies were encamped at the junction of Vrilittos and Hymettus mountains, Amphilitus, augur of the temple shows up in front of Peisistratos and gives him an oracle, assuring him that he has gained the favor of the goddess Athena.

At the environs of Gargittos and Pallini where the battle took place, tombs with monuments are set at each grave of the soldiers, who are buried along with their favourite heirlooms, such as vessels, jewelry and coins.

When Peisistratos dies, in 527 BC, Cleisthenes, a prominent political figure of this era, tries to give an end to tyranny, while conflicts between Athenians and Spartans, Chalkidans and Thebans take place.

However, their plans fail when he is informed the forerunner Leo and by one surprising attack he manages to extinguish his enemies at Gargittos and at the same time scatter the other team.

Recent excavations at a prehistoric graveyard at Fouresi Hill brought to light ruins of a palaiochristian temple that proves the existence of a Christian community.

Arvanite mercenaries from Northern Epirus were sent to Mesogea to protect the Duchy of Athens which was established in 1205 by the Franks, after the conquest of Constantinople during the Fourth Crusade.

In his attempt to give financial independence to the monastery, Saint Timotheos bought pieces of the land around, displacing the shepherds away to a place called Labrika, near modern Koropi.

During the years of the Hellenic independence, in 1835 the Municipality of Myrinous of the province of Attica is established by the Decree BD of 1 October (FEK 17) and the seat is located at the settlement of Liopesi, center of the ancient trittys of Paiania.

Such [a] name never existed according to older and recent geographers, but the ancient Greeks called Kechropian the Acropolis and a part lying between Eleusina and Aharnes."

The land of modern Gerakas is covered by cultivated fields used by the Arvanites and native residents of Liopesi, Charvati and Kantza who live and work at the Mesogean plain.

At the same time, Pallini alongside Kantza border on "Upper Paiania" that is basically built around the Stavros church at the most northeastern part of the Ymittos mountain, near Agia Paraskevi.

In 1966, a small settlement near the Lavriou Avenue, connecting Athens with Lavrium, among the pits, tries unsuccessfully for a secession from Paiania, in order to be recognized as Commune of Glyka Nera.

Meanwhile, their western neighbours at Agia Paraskevi meet an unexpected urban development and a great population growth coming from Athens, up to the northern part of the mountain.

In 1974 another gathering of Gerakiotes takes place and after the police gives their permission, they visit a lawyer and constitute the memorandum of the new administrative entity they desire to create.

Since 2001 and especially after the great transportation works that have been completed, Gerakas had a rapid growth in population, mostly Athenians leaving the center of the metropolitan area.

sources:ESYE, Municipality of Gerakas 2004 was a significant date for the area, as the Athens Olympic Games left an enormous heritage to the city.

Some of the great works completed are the Attiki Odos, the Ymittos Circuital Road, as well as the Doukissis Plakentias and Pallini Metro and Suburban Railway stations.

The great transportational works give the spark for mass construction of the farmlands which are cut into small fields, while the building activity gave an architectural uniformity to the city.

During the recent years, Gerakas is trying to balance between the variant forms of development and its urbanization, while it seems to "flirt" with the borders of the Athens metropolitan city.
