Uluru; A large sandstone rock formation in the heart of Australia, listed as a UNESCO World Heritage Site. Also known as Ayers Rock, the formation is sacred ground to the Pitjantjatjara Anangu; the Aboriginal people of this area. Uluru sets itself apart by the fact that it appears to change colour during different times of the day and year. The rock is especially remarkable during sunrise and sunset as this is when it turns into a reddish colour. It is not only a spectacular natural formation, but it is also a profoundly spiritual place. You feel a powerful presence when you first cast your eyes on it.
