According to historical records engraved on a stone tablet inside, this mosque was built in 742 during the Tang Dynasty (618-907). This was a result of Islam being introduced into Northwest China by Arab merchants and travelers from Persia and Afghanistan during the mid-7th century when some of them settled down in China and married women of Han Nationality. Their descendants became Muslim of today. The Muslim played an important role in the unifications of China during the Yuan and Ming Dynasties. Hence, other mosques were also built to honor them.

In Xian, it is really well worth a trip to see the Great Mosque, not only for its centuries-old history but also for its particular design of mixed architecture - traditional Muslim and Chinese styles.

Occupying an area of over 12,000 square meters, the Great Mosque is divided into four courtyards, 250 meters long and 47 meters wide with a well-arranged layout. Landscaped with gardens, the further one strolls into its interior, the more serene one feels.

The first courtyard contains an elaborate wooden arch nine meters high covered with glazed tiles that dates back to the 17th century. In the center of the second courtyard, a stone arch stands with two steles on both sides. On one stele is the script of a famous calligrapher named Mi Fu of the Song Dynasty; the other is from Dong Qichang, a calligrapher of the Ming Dynasty. Their calligraphy because of such elegant yet powerful characters is considered to be a great treasure in the art of handwriting.

At the entrance to the third courtyard is a hall that contains many steles from ancient times. As visitors enter this courtyard, they will see the Xingxin Tower, a place where Muslims come to attend prayer services. A 'Phoenix' placed in the fourth courtyard, the principal pavilion of this great mosque complex, contains the Prayer Hall, the surrounding walls of which are covered with colored designs. This Hall can easily hold 1,000 people at a time and according to traditional custom, prayer services are held five times everyday respectively at dawn, noon, afternoon, dusk and night.

Mosques in China, this Great Mosque is the only one open to visitors from 8 a.m. to 7:30 p.m. Non-Muslims, however, are not admitted to the main prayer hall or during times of prayer.
