Doğan Bey’s grave is located in the Doğanbey neighborhood, next to the mosque that gave the neighborhood its name and no longer exists today.
Doğan Bey, who lived during the 14th and 15th centuries—though his exact dates of birth and death are unknown—was one of the leading Ottoman akıncı beys who rendered significant service during his time. He served as the commander of Niğbolu Castle during the reign of Yıldırım Bayezid.
