Long Wall (Thracian Chersonese)

The Long Wall (Ancient Greek: Μακρὸν τεῖχος) or Wall of Agora (Ancient Greek: Ἀγοραῖον τεῖχος) after the nearby city, was a defensive wall at the base of the Thracian Chersonese (the modern peninsula of Gallipoli) in Antiquity.

The Long Wall was actually a succession of walls on the base of the Thracian Chersonese, the first of which was built in the late 6th century BC by the Athenian magnate Miltiades the Elder. Miltiades became the ruler of the Greek city-states of the Thracian Chersonese in 516 BC. Threatened by the warlike Apsinthians, the historian Herodotus (The Histories, VI.36.2) reports that "his first act was to wall off the isthmus of the Chersonese from the city of Cardia across to Pactya, so that the Apsinthians would not be able to harm them by invading their land". Herodotus recorded the length of the isthmus as thirty-six stadia, or approximately 7.2 km. It is unknown how long the wall of Miltiades stood, but apparently it was left derelict soon after, for in the 5th century it had to be rebuilt by Pericles (Plutarch, Pericles, 19.1), and was again restored in the early 4th century by the Spartan commander Dercylidas (Xenophon, Hellenica, III.2.8–10; Diodorus Siculus, Bibliotheca, XIV.38.7), to protect the peninsula from raids by the Thracian tribes.
