| Uluru, also called Ayers Rock, is one of the largest monoliths, or rock masses, in the world. Located in Uluru-Kata Tjuta National Park in central Australia, the monolith measures about 3.6 km (2.2 mi) long and 348 m (1,142 ft) high. Rock paintings made thousands of years ago by Aboriginal artists cover the walls of many caves in Uluru. |
