Guide's Note
Acem Reis Mosque is a small-scale Ottoman masjid dating back to the Fatih Sultan Mehmet period, around 1480. The structure, which stands out with its location in the middle of the street in Demirtaşpaşa Neighborhood, reflects classical Ottoman architectural features with its square plan, single dome, and single-balconied minaret. The mosque's walls are built with brick and cut stone, and there is a portico at its entrance. Only three graves have survived to the present day in the cemetery of the structure, also known as "Arap Dede Mosque." Visitors generally view the historical value and modest scale of the mosque positively.
While the mosque is open for worship, we recommend planning your visit in advance; one visitor noted that the door was closed just a few minutes before the call to prayer.
- Maintenance and cleanliness: Multiple visitors report that the courtyard and interior are not in good condition due to neglect.
- Toilet and ablution area: It is emphasized that the existing toilet is inadequate and these areas should be reorganized by the municipality.
- Visiting hours: Visits should be planned considering that the door may be closed outside of prayer times.
About Acem Reis Mosque
Acem Reis Mosque is a modest structure that remains in the shadow of larger mosques on Bursa's tourist map but offers clues about the city's Ottoman-era neighborhood life. Built during the reign of Fatih Sultan Mehmed by a Persian merchant named Bedreddin Mahmud, this mosque takes its name from its patron's nickname. Its popular name, Arap Dede Mosque, is a reflection of the oral tradition that developed around the structure over time.
The square-planned structure, with its single dome and brick-and-stone walls, exhibits the typical features of early Ottoman neighborhood masjids. The portico at the entrance is designed in accordance with the architectural understanding of the period. It may appear as an ordinary structure next to grand complexes; however, it holds a special place in embodying the tradition of neighborhood masjids in Ottoman urbanism.
When to Visit?
There is no specific seasonal requirement for visiting Acem Reis Mosque when planning a trip alongside other historical structures in Bursa. It can be visited throughout the year; weather conditions are more favorable in spring and autumn. The interior of the mosque is quieter after morning prayer or at noon, allowing for a more relaxed visit during these hours.
Bursa can be quite hot in the summer months; it is more sensible to prefer visiting in the early morning or late afternoon. Since the area around the mosque can become crowded during Friday prayer times, those wishing to take photos or examine the structure from the outside should consider these hours.
How to Get There?
Acem Reis Mosque is located in Kız Yakup Neighborhood of Osmangazi district in Bursa, at the beginning of Güzel Kız Street and at a three-way intersection. It is situated east of Demirtaş Mosque; you can use Demirtaş Mosque as a reference point to orient yourself.
After reaching the Osmangazi area from Bursa city center by municipal buses or minibuses, you can walk or take a short taxi ride to the mosque. If you come by car, it is possible to find parking on the surrounding streets; caution is needed due to the narrow neighborhood streets.
How Much Time Should Be Allocated?
Since Acem Reis Mosque is a small-scale structure, a 15–30 minute visit alone is sufficient. This duration is generally enough to examine the exterior and interior of the building and take photos.
It would be much more efficient to combine the mosque with other historical sites in Bursa as part of a half-day or full-day itinerary. It can be visited along with the nearby Demirtaş Mosque and other historical structures in Osmangazi.
