Shipton's Arch is a conglomerate natural arch in China's Xinjiang Uyghur Autonomous Region. It is located in Kizilsu Kirghiz Autonomous Prefecture west-northwest of Kashgar, near the village of Artux, at an altitude of 2,973 metres. It is probably the world's tallest natural arch.
Though long familiar to locals (the south side of the arch is visible from the plain below) it was famously "discovered" in 1947 by English mountaineer Eric Shipton during his tenure as the British consul in Kashgar – and made known to the West in his book Mountains of Tartary.
The height of the arch is estimated to be 1,500 feet (460 m), about the height of the Empire State Building. The span of the arch is roughly 180 feet (55 m).
The "true" height of the arch is debatable: viewing the arch from the north (normal approach route) it appears to be 200 feet (61 m) tall from the top of the 100 feet (30 m) rubble pile; from the south side, the height is closer to the estimated 1,500 feet (460 m).
