Najiahu mosque, Islamic heritage site in Yongning County, China

Najiahu Mosque is a religious complex in Yongning County that combines Islamic architectural traditions with regional building styles. The structure features multiple courtyards, prayer halls, and towers arranged to create a cohesive sanctuary space for worshippers.

The mosque was built in 1524, during the third year of the Jiajing era of the Ming dynasty, by descendants of the Yuan official Sayyid Ajall Shams al-Din who carried the Na surname. It was listed as a protected site of the Ningxia Hui Autonomous Region in 1988. One Arabic-language source instead places its construction at the start of the Yuan dynasty.

The mosque bears the name of the Najiahu village where it stands, and its congregation traces descent from the family of Sayyid Ajall Shams al-Din, a Yuan-dynasty official; the surname Na comes from the Chinese rendering of his name. The complex covers about 9,000 square metres and mixes Chinese and Arab architectural elements, with a central courtyard framed by wooden and brick buildings whose outer walls carry geometric patterns and Arabic calligraphy.

The site is open to visitors but requires respect for prayer times and religious spaces. It is best to check current visiting guidelines beforehand and dress appropriately when planning your visit.

The mosque was listed as a protected site of the Ningxia Hui Autonomous Region in 1988, not at national level; the national-level designation in the identity data conflicts with the sources. Its protected category covers both the old building and its role as a historical commemorative structure.
