Uluṟu (called Ayers Rock in English) is the largest rock massif in outback Australia. Surrounded by the completely flat surface of the bush, Uluru is visible from tens of kilometers away and is famous for its intense red colouration, which changes spectacularly (from ochre, to gold, to bronze, to purple) according to the time of day and season; characteristics that make it one of the icons of Australia. The surface, which appears almost completely smooth from a distance, reveals many springs, pools, caves, peculiar erosion phenomena and ancient paintings as you approach. Uluru is located in Australia (Oceania) in the Northern Territory, in the Uluru-Kata Tjuta National Park, 450 km southwest of the city of Alice Springs. It is a sacred Aboriginal site, formally handed over by the Australian Government to the indigenous people of the place in 1985.
