Grand Kuqa Mosque is the place for Muslim people in Kuqa to worship the God. It is located in the highest place of Heidun Bazaar in Kuqa County. It is the second largest mosque in Xinjiang after the Id Kah Mosque in Karshgar and has a capacity of 3,000 worshipers.
After the spread of Islam in Kuqa, the Grand Kuqa Mosque was built in the 15th Century and reconstructed in 1931 after being damaged by fire, which first signified dominance of Islam over Buddhism in Xinjiang.
The main dome of the Grand Mosque over the entrance was built with 300,000 eggs and cement mixture. The great praying hall is supported by 88 pillars, embellished with carved designs and in many colors, a fine example of Uygur architecture. It can accommodate 1,000 prayers.
