Koyun Baba Bridge, Stone bridge in Osmancık, Çorum Province, Turkey

Osmancık İkinci Beyazıt Bridge is a stone structure crossing the Kızılırmak River with fifteen arches spanning roughly 250 meters and measuring about 7.5 meters wide. It features stone railings along both sides and remains largely unchanged from its original design.

Sultan Beyazit II commissioned this bridge between 1484 and 1489 during a major period of infrastructure development in the Ottoman Empire. Its construction reflected efforts to improve regional connectivity during this era of expansion.

The bridge takes its name from Koyunbaba, a local spiritual figure whose shrine sits nearby, blending religious significance into everyday crossing. Walking across, you notice how the sacred and the practical coexist in this landscape.

The bridge welcomes both pedestrians and vehicles with no tolls charged for crossing. It remains sturdy enough for daily use and offers a reliable route for local travelers and visitors exploring the region.

Tar-coated wooden stakes anchor the foundations to prevent the structure from sinking into the river bed. This clever engineering solution reveals how builders overcame the challenges of soft ground conditions.
