Hacı Seyfettin Mosque
It was built by Başçı Hacı Seyfettin in the 15th century, during the reign of Mehmed the Conqueror (1451-1481). After remaining in ruins for a while, it was rebuilt in 1487 by a philanthropist named Mevlana Hayrettin. Since it is known that the mosque was not damaged in the 1855 earthquake, it is thought to have survived in its original form.

The mosque has a rectangular plan scheme, including the main place of worship and the final congregation place.

Its gable-walled façade, which is frequently seen in Bursa mosques, is unusually designed with two large pointed arches.

The building was restored in 1487 and 1962.
