????Qingjing Mosque is one of the oldest mosque sites existing in China today. It is located in the middle part of Tumen Street, Licheng District of Quanzhou, which was a Muslim community in ancient times. The mosque was built in 1009 (the 400th year by Muslim lunar calendar or the 2nd year of the Dazhong Xiangfu period of the Northern Song Dynasty) and repaired in 1310 (the 701st year by Muslim lunar calendar or the 3rd year of the Zhida reign of the Yuan Dynasty). Existing structures include the stone gate tower and the Fengtian Altar, basically retaining the architectural style of the Song and Yuan period. Qingjing Mosque is an architectural mixture blending the typical style of Middle-Age mosques in West Asia and elements of Chinese traditional buildings. It bears a testimony to close economic and cultural exchanges and fusions between China and the Arab region during the prosperous period of maritime trade in Quanzhou from the 10th to 14th centuries. Vaults of the gate tower of Qingjing Mosque are extremely similar with the auspicious pattern of turtle back and the eight-purlin caisson ceiling in Chinese architectural tradition. They demonstrate the fusion between Chinese tradition and Islamic architectural design. Qingjing Mosque has long been a sacred place worshipped by Muslims from around the world.
