History Antiquity Çatalca's ancient Greek name was Ergisce or Ergiske (). It was an ancient Greek city in Thrace, located in the region of the Propontis. According to ancient texts, the Greek name is after Ergiscus (Ἐργίσκος), a son of Poseidon through the naiad (nymph) Aba (Ἄβα). In Greek mythology, Aba was a nymph and she is presumed to be a daughter of the river Hebros. The site is now occupied in part by modern Çatalca. Under Roman rule, it was named Metrae or Metre and was important enough in the Late Roman province of Europa to become a suffragan of its capital Heraclea's Metropolitan Archbishop, yet was to fade.

The Çatalca fortifications formed a line across the peninsula, the "Chataldja line", which became the armistice line of 3 December 1912, after Bulgaria decided not to attack Adrianople at that time.
