Sakarya is a northwestern Turkish province straddling forested hills, the valley of the Sakarya River, and the pristine shores of Sapanca Lake. Just 150 km east of Istanbul, it blends industrial energy with remarkable natural scenery, Ottoman heritage, and Battle of Sakarya battlefield sites that shaped modern Turkey.
The Sakarya River (ancient Sangarios) has been a significant waterway since antiquity, forming a natural boundary in Bithynia and Phrygia. The region passed through Hittite, Phrygian, Byzantine, Seljuk, and Ottoman hands before becoming part of modern Turkey. The decisive Battle of Sakarya (23 August–13 September 1921) during Turkey's War of Independence was fought largely in this river valley, marking the turning point that secured Ankara as the new capital. Taraklı preserves some of the finest extant Ottoman domestic architecture in Turkey.
