This impressive vaulted mausoleum is situated in the east suburb of Alimale, northeast of Huocheng County. Tuheilutiemuer-han, a legendary king of Chagatai Khanate, is the seventh-generation descendent of Genghis Khan. In 1346 the 16-year-old Tuheilutiemuer-han was king of Mengwuersitan. He embraced Islam at the age of 18. In 1352 he forced the 160,000 Mongolians under his rule to convert to Islam, thus promoting the spread of Islam in Xinjiang. In March 1360, he waged a war to unify the Hezhong area. He succeeded in temporarily unifying Chagatai Khanate. In 1363 Tuheilutiemuerhan died and was buried here. The main gate of the burial hall of the mausoleum faces east; the front walls are covered with 26 kinds of glazed bricks of violet, blue, and white, on which are carved various geometrical patterns. The uppermost part of the gate is covered with blue glazed bricks, with embedded eulogies in Arabic. The whole structure is both immense and simple, magnificent and graceful. Inside the hall there are no supporting columns, with four empty walls, and there are stairs leading to the top level. Tuheilutiemuerhan Mazar is the oldest Islamic-style architecture in Xinjiang. Parallel to the mausoleum is a vaulted mausoleum, smaller in size, said to be the mausoleum of the younger sister of Tuheilutiemuerhan. Tuheilutiemuerhan Mazar has become a place for many Mus­lims to worship.
