Uluru is recognised as Australia's most natural icon and has become a focal point for Australia and the world's acknowledgement of Australian indigenous culture. The sandstone monolith stands high with most of its bulk below the ground. To Anangu (local indigenous people), Uluru is a place name and this Rock has a number of different landmarks where many ancestral beings have interacted with the landscape and/or each other, some even believed to still reside here. Kata Tjuta, meaning 'many heads', is a sacred place relating to knowledge that is considered very powerful and dangerous, only suitable for initiated men. It is made up of a group of 36 conglomerate rock domes that date back 500 million years.
