Inside the ancient site of Keramikos, lie the remains of the city wall built by Themistocles in 479 BC, and rebuilt by Konon in 394 BC. The wall is broken by the foundations of two gates. The first, the Sacred Gate, spanned the Sacred Way and was the one by which pilgrims from Eleusis entered the city during the annual Eleusian procession. The second, the Dipylon Gate , northeast of the Sacred Gate, was the city’s main entrance and where the Panathenaic Procession began.
It was also where the city’s prostitutes gathered to offer their services to travellers. From a platform outside the Dipylon Gate, Pericles gave his famous speech extolling the virtues of Athens and honouring those who died in the first year of the Peloponnesian Wars.
