Koyunbaba Bridge is a 19-arched Ottoman bridge made of yellow cut stone, built over the Kızılırmak River in Osmancık district of Çorum during the reign of Bayezid II (1484-1489); it features a castle at one end and a mosque at the other.
Koyunbaba Bridge is a stone arch bridge crossing the Kızılırmak River in the center of Osmancık district. Its construction began in 1484 and was completed in 1489. Thus, it is a work built in the early years of Bayezid II's reign. It is 250 meters long, 7.5 meters wide, and built on 19 pointed arches. Due to the riverbed filling with sediment over time, only 15 of the arches are visible today.
The bridge is made of yellow cut stone, laid in five parallel rows. Its Arabic inscription commemorates the builder of the bridge but says nothing about the identity of the architect. It takes its name from Koyunbaba, a renowned Turkish saint in the region. A detail frequently mentioned by visitors is that a mosque stands at one end of the bridge and Osmancık Castle at the other. This adds another layer to the scenery.
Comments suggest that the bridge looks more impressive in the late afternoon when the weather cools down. Those who visit in the midday heat state that they get tired but it is worth seeing. Recently, the bridge's night illumination also made news, which is another reason making an evening visit attractive.

Guide's Note
When to Visit?
The bridge is open year-round and can be visited for free. Comments frequently state that the midday heat is uncomfortable, and late afternoon or near sunset hours are more enjoyable. In spring and autumn, the water level of the Kızılırmak also appears visually more vibrant.
How to Get There?
From Çorum city center to Osmancık is 61 km, taking between 45 minutes to 1 hour by car. Regular bus and minibus services depart from Çorum bus station to Osmancık. If you are going by your own car, simply follow the Çorum-Osmancık-Tosya highway. The bridge is on this road, very close to the district center.
How Much Time Should Be Allocated?
Seeing the bridge and taking photos takes 20-40 minutes. It's ideal for a short break if you're on the road. In Osmancık, you can combine it with Koyunbaba Tomb, Osmancık Castle, and Akşemsettin Mosque for a half-day tour.
Route Suggestion
Approaching the bridge from Osmancık Castle completes the view. When viewed from the foot of the castle, the bridge, mosque, and river all fit into the same frame. After visiting the castle, walking across the bridge and stopping by Koyunbaba Tomb is a logical sequence.
Photo Spots
The presence of a mosque at one end and a castle at the other enriches the frame. Low-angle shots taken from the riverbank better show the sharpness of the arches. When the evening lighting comes on, night photography also becomes an option.
Things to Pay Attention To
Since the bridge is a historical structure, it is necessary to walk carefully on it, as the stone surface can sometimes be slippery. In mid-summer, shade decreases during midday hours, so don't go without a water bottle. As the area is on a main road, attention must be paid to traffic flow.
Brief History
The bridge's inscription mentions Sultan Bayezid's name and the order for its construction, but there is no information about the architect. The tomb of Koyunbaba, after whom the bridge is named, is also nearby and can be included in the same itinerary. The structure was an important part of the transportation network within Anatolia during the Ottoman period.
