Çatalca

Çatalca spreads across the Thracian ridge between the Sea of Marmara and the Black Sea, northwest of Constantinople. Forests, fields, springs and rolling uplands make the district a broad rural approach to the imperial city. Roads from the capital crossed the ridge toward Adrianople and the Balkan frontier, while coastal valleys gave access to the Marmara shore.

The ancient town of Ergisce belonged to the Propontis region, its name linked in myth to Ergiscus, son of Poseidon. Under Rome the place was known as Metrae and became a suffragan bishopric in the late province of Europa, subject to the metropolitan see of Heraclea. Byzantine churches and roads preserved its position within the ecclesiastical and military geography of eastern Thrace.

Ottoman conquest placed Çatalca within the rural hinterland of Constantinople. Villages combined grain farming, stock raising and forest work, and the ridge carried traffic between the capital and the Balkan provinces. Greek, Turkish and other communities occupied the district’s valleys and villages over the centuries. Çatalca’s importance came from this passage across Thrace, where land routes and coastal waters converged northwest of the capital.
