The history of Rafina is rooted in deep antiquity. The modern city is located on the site of the ancient Attic deme (administrative district) known as Araphen. The first written records and the official establishment of the settlement as an administrative unit date back to the end of the 6th century BC, when Araphen became part of the Aegeis tribe during the reforms of Cleisthenes. According to ancient Greek legends, the area received its name in honor of the hero Araphenas, who was considered its first ruler and mythical founder.
A key factor in the development of Araphen has always been its advantageous geographical position. Located on the eastern coast of Attica, the settlement possessed a convenient natural harbor, which predetermined its fate. Since ancient times, the port served as an important departure point for ships to the island of Euboea (specifically to the poleis of Karystos and Styra), providing communication between the mainland and the islands. Furthermore, this location allowed for control over the sea routes in the Euripus Strait, giving the settlement not only commercial but also military significance.
The economy of early Araphen was based on a combination of maritime trade and agriculture; however, the site gained its greatest fame through its spiritual life. The center of attraction was the famous sanctuary of Artemis Tauropolos. The cult of the goddess played a vital role in the identity of the local residents: large-scale festivals, the Tauropolia, were regularly held here, attracting pilgrims from other parts of Attica and turning the small port town into a significant religious center for the region.
