Najiaying Mosque, Islamic center in Tonghai County, China

Najiaying Mosque is a mosque in Najiaying Village, Nagu Town, Tonghai County, Yuxi, Yunnan. Its 2004 prayer hall, designed by the Yunnan Provincial Architectural Design Institute, has four floors, a dome and four 72.4-metre minarets; the second and third floors hold 6,000 worshippers. In February 2024 the jade-green dome and minarets were rebuilt in Chinese style, with a round pyramidal roof. The former hall, moved 250 metres east, serves as a women's mosque for 800.

The founding date is recorded variously: 13th century under Näsir al-Din, the Yuan era, 1370, or the Kangxi reign; scholar Li Xinghua places it in the 15th century, enlarged to a large scale under Kangxi. Closed during the Cultural Revolution, it was expanded in 1975 and 1984, gained a teaching building in 1989, and from 2001 was rebuilt: the Yunnan Provincial Architectural Design Institute designed a new hall opened on 2 October 2004, funded by about 30 million yuan, mostly village donations. The old hall was moved 250 m east as a women's mosque; in 2023 the new hall's dome was converted to a Chinese-style roof, completed February 2024.

The mosque serves the Muslim community of Najiaying village, at 76 Zhongxun Road in Nazhen town. Its older prayer hall, moved 250 metres east in 2004, became a women's mosque seating up to 800. The 2004 reconstruction cost about 30 million yuan, funded mainly by villagers' donations.

The mosque stands at 76 Zhongxun Road in Najia village, Najia ancient town, Tonghai County. The 2004 prayer hall has a ground-floor assembly room and prayer halls on the second and third floors, with a multi-purpose hall on the fourth. The former hall, moved 250 m east, now serves as a women's mosque for up to 800 worshippers.

The 2004 prayer hall was built in an Arab style with a jade-green dome and four 72.4-metre minarets. In February 2024 the exterior was converted to a Chinese-style round pyramidal roof with Chinese-style minarets, after the May 2023 demolition of the dome led to clashes between locals and police.
