Hamza Bey (d.1461), "the conqueror of Izmir", was a commander of armies during the rule of Mehmed I, Murad II and Mehmed II and served also as vizier under Murad II. The complex he built in Bursa consists of a mosque and two tombs (türbe), located on a hill in the vicinity of the Muradiye Complex overlooking the plain of Bursa.
The mosque was built originally as a mescid and the minber was placed later in 1615. It is based on a reverse T-plan with a five-bay domed portico leading to a central hall flanked with eyvans on the east and west and a larger eyvan with mihrab niche to the south. Domes of equal diameter crown the central hall and the southern eyvan, the former slightly higher than the latter. The side eyvans are roofed with domes joint with barrel-vaults. A small tomb adjoins the mosque to the west of the portico, ornamented with colored glass windows. It contains three tombs without names, possibly those of the wife and daughters of Hamza Bey.
The tomb of the complex is an octagonal building covered with a dome. It includes the twelve graves including that of Hamza Bey.
