Literally, 10's of thousands of years. Gabarnmang is older, and has been continuously occupied and in use, with only a break in occupation on the order of 50 years, last century, when it was "forgotten about" by the caretakers, in order to protect it ... only to be re-discovered recently (this century). It is a truly extraordinary site and I personally consider it the holiest of all human sites, ever. More holy than any other - in constant use as a school and commons, for 10's of thousands of years of human existence, containing an extraordinary collection of art, both ancient and contemporary ... probably one of the most important collections of human art, ever. If Australians had any decency they'd immediately sever ties with the British and make this site the seat of their new sovereign - its that powerful a record of human civilization, imho.
