The Orhan Gazi Mosque in Söğüt, Bilecik province, is one of the earliest surviving Ottoman mosques in Anatolia, built in honor of Orhan I (r. 1324–1362), the second ruler of the Ottoman state. Orhan Gazi was the son of Osman I and presided over the first dramatic expansion of the Ottoman realm, capturing Bursa (1326), İznik (1331), and İzmit (1337) from the Byzantine Empire. The mosque in Söğüt stands as a monument to this pivotal period of Ottoman state-formation in northwestern Turkey. The building follows the early Ottoman single-domed mosque type, characterized by thick stone walls, a shallow portico of pointed arches, and a low minaret typical of Bithynian Ottoman architecture before later Persian and Timurid stylistic influences arrived. Interior plasterwork retains traces of geometric decoration from the 14th and 15th centuries, and the mihrab (prayer niche) is carved in a restrained early Ottoman style. The mosque underwent repairs in the 19th century under the direction of the local kadı, and again in the 1990s by the General Directorate of Foundations (Vakıflar Genel Müdürlüğü), which oversees Ottoman religious monuments throughout Turkey. The site remains in active use for Friday prayers. Its position in Söğüt alongside the Ertuğrul Gazi Tomb and the district museum makes it an integral part of the Ottoman heritage circuit of Bilecik province, illustrating the architectural vocabulary of the Ottoman state in its formative decades.
