Jinan North Mosque was built during the Hongzhi era of the Ming dynasty (1488-1505), making it more than 400 years old and one of China's older mosques. It stands at No. 23 Yongchang Street in the Hui Muslim quarter of Shizhong District, having undergone repeated repairs and expansions through the Qing dynasty and the early Republican period; it is now listed as a protected cultural heritage site at the provincial level. The mosque follows a two-courtyard layout along a single axis, with a main gate, inner gate, prayer hall, and moon-viewing tower. The spacious prayer hall — about 900 square meters — rests on 40 massive wooden columns, with red lacquered floors and dozens of hanging lanterns, and can seat nearly 1,000 worshippers. Inside hangs a calligraphed plaque reading "Pure Islamic Teaching," written by the Qing official Li Hongzhang. Today the mosque remains an active center for Jinan's Hui Muslim community, welcoming Muslim visitors who wish to pray or explore this rare architectural heritage blending imperial Chinese style with Islamic artistic elements.
