The mosque is historically attributed to the conquest era of the Ottoman state in the 1300s.
Adapazarı's urban history is intricately linked to this site, which acted as an early anchor for regional settlement.
The mosque has been rebuilt multiple times specifically to recover from the frequent seismic activity in the Sakarya fault zone.
Despite modern city planning, the mosque remains situated on a site that has continuously functioned as a religious space for nearly seven centuries.
Orhan Mosque is the oldest historical building in Adapazarı, originally commissioned by Orhan Ghazi, the second ruler of the Ottoman Empire. The current structure is not the original 14th-century edifice, as the site has undergone multiple reconstructions following severe regional earthquakes. It serves as a focal point for the city's historic center near the Adapazarı Grand Bazaar. The architecture reflects traditional Ottoman mosque design, featuring a prominent central dome and a single minaret. It remains an active place of worship serving the local community in the Sakarya province. The surrounding area preserves a denser urban fabric typical of old Turkish commercial centers.
