Porto Rafti means "the tailor's port". The tailor is a statue.
On Raftis, the larger islet at the mouth of the bay, sits a colossal marble figure: an enthroned woman in heavy, elaborate drapery. She has lost her head and arms. Seen from the water at a distance, the seated silhouette with its raised stump of an arm looked to sailors like a tailor at work, and the name stuck to the whole bay.
Who she actually is has never been settled. Some argue for Regilla, wife of Herodes Atticus; others for the goddess Cybele or Rhea. The name's origin is disputed too: alongside the tailor story, scholars have proposed the Albanian rrapthi, "small plane tree", and a link to the worship of Rhea across eastern Attica.
The islets were not always empty. Archaeologists have found evidence of Mycenaean settlement on them, and the bay served the ancient demes of Prasiai, Steiria and Koroni. It stayed a working trading port until the collapse of the Roman Empire.
A darker footnote. In late April 1941, after the German invasion of Greece, this bay was one of the points from which Allied troops were evacuated. The quiet swimming beaches were an embarkation line within living memory.
