Located 18 miles west, Katatjuta (The Olgas) is a recurring presence in the background of Uluru. Believed by Aboriginal people to have been inhabited by mythological ancestors, it is a place to be approached with caution. There is a sense of mystery and apprehension at Katatjuta, with the complex domed structures with their own rows of "windows" suggesting an abandoned temple city where, due to its mysterious symmetry, space circulates. The uneasy feeling of having intruded and being watched influenced the filming. (Arthur Cantrill & Corinne Cantrill)
