The area is an inland part of the south Athenian plain, situated between the foothills of Mount Hymettus and the southern coastal zone of Athens on the Saronic Gulf.

The area displays some of the earliest urban settlements in Europe, with archeological sites showing continuous development from the Neolithic and Bronze Age periods.

The name Euonymeia is documented in the Ethnica (Greek: Ἐθνικά), the gazetteer by 6th century CE scholar Stephanus of Byzantium, considered the earliest authoritative work on Mediterranean toponyms.

[5] Systematic archeological excavation of the area has not been conducted, yet numerous construction projects during the intensive urban development of the later half of the twentieth century led to important circumstantial discoveries, which shed light on the historic timeline of the settlement.

[6] The hills of Euonymeia, together with the adjacent coastal promontory of Agios Kosmas, the ancient Akra Kolias,[7] are the two most important sites of Neolithic and Aegean Bronze Age development in the area of Athens prior to ca.

[11] In 2012, prehistoric masonry, which has yet to be dated, was recognized on the summit of Pan's Hill (Greek: Λόφος Πανί, romanized: Lofos Pani),[12] the highest elevation point in Euonymeia.

[15][16] In 2006, work on the Alimos Metro station 300 metres (980 ft) South from the mound unearthed a large workshop complex[17] from the same era with installations for ceramic production, including a kiln and potters wheel.

[18] This workshop included hydraulic installations with wells and water conduits used in the processing of flax into textiles for the production of table wares, and for sails and ropes used on Mycenaean era ships.

[20] During the Geometric period of the Hellenic Dark Ages (10th to 8th centuries BCE), the area continued to be inhabited, with notable pottery production from the Trachones workshop.

Geometric era finds in Euonymeia concentrate 500 metres (1,600 ft) to the West of the Myceneaen site at Kontopigado, on a hill by the Trachones stream on the current Geroulanou Estate.

Geometric graves and pottery have been found around the estate providing evidence that unlike in Athens and neighboring communities, Euonymeia, together with Anavyssos further south, were peculiar in practicing cremation as the main burial rite during this period.

[31] The town was on the Urban Way (Greek: Αστική Ὁδός, romanized: Astiki Hodós), the major ancient road linking Athens to the Temple of Poseidon at Sounion, and the all-important silver mines at Laurium.

Remains of the Urban Way have been unearthed in multiple sites along the modern Vouliagmenis Avenue, positioning this ancient thoroughfare adjacent to the most important installations in Euonymos.

[2][4] Nonetheless, it retained urban settlement throughout the Early Christian and Byzantine eras as testified by the ruins of the Paleochristian Basilica of the Holy Apostles (ca.

During this time, in defiance of the Roman Catholic allegiance to the Frankish lord of Athens Othon de la Roche, the Orthodox church of the "Presentation of Mary of Trachones" (Greek: Εισοδίων Θεοτόκου Τραχώνων, Isodíon Theotókou Trachónon) was constructed 300 metres (980 ft) West of the Euonymos Theater.

[44] This area features Karaiskakis square and park, which includes the "Klouva" outdoor public basketball court,[45] and the municipal amphitheater, where the major community events take place.
