This stunning, massive sandstone rock formation in central Australia is a site to behold. Its official name is Uluru, but it's better known as Ayers Rock having been named so after Sir Henry Ayers (by William Gosse) in 1873 .

The official name, Uluru, was derived from the indigenous Australians, who have been in the area for the last 10 000 years. 

Located in the southern part of the Northern Territory, this UNESCO World Heritage Site is believed to have been formed 600 million years ago. 

According to uluru-australia.com, the mountain "originally sat at the bottom of a sea, but today stands 348m above ground. One of the most startling Uluru facts however, is that some 2.5kms of its bulk is underground."

Around it, there are plenty of springs, waterholes and ancient  paintings. The Aboriginal people consider Uluru deeply sacred and are known to be against any climbing of the rock.
