<b>Uluru</b>, also referred to as <b>Ayers Rock</b>, is a large
sandstone rock formation in the southern part of the
Northern Territory, central Australia. It lies 335 km (208 mi)
south west of the nearest large town, Alice Springs; 450 km
(280 mi) by road. Kata Tjuta and Uluru are the two major
features of the Uluru - Kata Tjuta National Park. Uluru is
sacred to the Pitjantjatjara and Yankunytjatjara, the
Aboriginal people of the area. It has many springs, waterholes,
rock caves and ancient paintings. Uluru is listed as a World
