The Id Kah Mosque is the largest mosque in China and the religious center of Kashgar. The call to Prayer booming from the mosque can be heard throughout the city center. This is a rare thing in Socialist China.

It is said that this place was once a cemetery. The present Id Kah Mosque was built in 1442 as a very small structure. Several renovations and enlargements have created it with today's scale and style.

The whole complex occupies 16,800 square meters (about 4 acres) and consists of the courtyard, the Hall of Prayer, and the gate tower and as well as some other attached structures.

The mosque exemplifies grand Islamic architecture, with a rectangular entranceway, flanked by intricately designed, slender minarets. The facade of the mosque is filled with yellow and white tiling, interspersed with designs in blues and greens. Inside the mosque there are charming courtyards and gardens where worshippers assemble before entering the halls.
