The Tomb of the Hami Kings is a mausoleum complex in the centre of the city where nine generations of the Kumul Khanate rulers are interred alongside three Islamic missionaries. The main structure combines Uyghur and Chinese architectural elements — blue-tiled domes and arched doorways alongside upturned eaves — reflecting the Kumul sultans' careful positioning as both Muslim rulers and loyal Qing dynasty vassals. The complex was built over a period of nearly two centuries, with each new khan adding to the compound.
The adjacent Gai Si Mosque, built within the same walled compound, remains in active use. The tombs are open to visitors and the combination of Islamic calligraphy, coloured tilework, and the domestic Chinese architectural idioms used in the entry gates makes it one of the more architecturally interesting sites in Xinjiang. The nearby bazaar sells Hami melons in season, which are worth trying at the source.
