Shahidulla, also spelt Xaidulla, (altitude ca. 3,646 m or 11,962 ft), was a nomad camping ground and historical caravan halting place in the Karakash River valley, close to Khotan, in the southwestern part of Xinjiang Autonomous Region, China. The site contains the ruins of a historical fort which was demolished by the Chinese administration of Xinjiang between 1890 and 1892. The site lies next to the Chinese National Highway G219 between Kashgar and Tibet, 25 km east of Mazar and 115 km west of Dahongliutan.
The modern town of Saitula (Xeyidula) is located next to the old fort of Suget Karaul built by the Qing administration (of China) about 10 km (30 "Chinese miles") southeast of the original site. A modern People's Liberation Army barracks named Sanshili Yingfang or Sanshili Barracks (lit. '30 li barracks') is also located here. "Sanshili Barracks" is a more common name used by motorists along the G219 highway.
