Mazartagh is a mountain running from south to north in hinter land of the Taklamamakan Desert, not far from the Khotan River, occupying a communications point linking the south and the north. On the top of the Red Hill on the mountain there built an imposing fort, which covers an area of 1160 square meters. The walls of it consist of main walls, buttress and outer walls. The main walls are built with sun-dried bricks.
Muztagata Peak: It is situated in Akto County capped with snow and ice all the year round. The formidable peak stands in the Pamir Plateau setting off perfectly with the Karakul Lake. When summer and autumn come on, the resort became the base camp of climbers. The peak and the alpine lake surrounded by snow mountains are the most famous sights of Kizilsu prefecture.
There are some dwellings built with sun-dried bricks inside the fort, from which there ever have excavated Chinese, Tibetan and Khotanese doc uments on paper and wooden tablets. At a distance of 5 meters to the east of the fort stands a watchtower about 8 meters high. The fort dates from the Tang and Song times. Now it is listed as a major cultural site under the autonomous region protection.
