Located 2 kilometers (1.24 miles) east of the city of Turpan, Emin Tower (The Tower for Showing Gratitude to Eminhoja) also called "Su Gong Ta" and "The Turpan Tower" by the local Uigur, was built in 1777 to commemorate and praise ruler of Turpan, Emin Khoja who achieved brilliant military success in suppressing the armed rebellion raised by the Jungar aristocrats and was complete in 1778 by his son Suleman. It is one of the architectural gems of the Silk Road.
The plain sun-dried bricks taper skywards in patterns of rhombuses, ripples and varied four-petal flowers. On the surface of the cone small windows open in all sides. A seventy-one-step stair spirals upwards from the 10-meter- (32.8-foot-) diameter base to the top. There is a good view of the area from the second-storied balcony above the mosque. At the entrance a free-stand tablet records the history of the tower both in Uigur and Chinese.
The adjoining mosque, the biggest mosque in Turpan, has a beamed ceiling supported by simple wooden pillars and a domed scared area. The hall in it can hold up 1000 people and serves as an important hive for religious Festivals.
