The University of Adelaide is a public research university based in Adelaide, South Australia. Established in 1874, it is the third-oldest university in Australia. Its main campus in the Adelaide city centre includes many sandstone buildings of historical and architectural significance, such as Bonython Hall. Its royal charter awarded by Queen Victoria in 1881 allowed it to become the second university in the English-speaking world to confer degrees to women. It plans to merge with the neighbouring University of South Australia to form Adelaide University.
