[1] Built between 1854 and 1966 in the Victorian Academic Gothic Revival architectural style, the Quadrangle was designed and developed by numerous contributors including Edmund Blacket, James Barnet, and Leslie Wilkinson.

[4] Robert Strachan Wallace, the university's vice chancellor from 1928 to 1947, upon taking up his position found the quadrangle to be "overgrown, and the grounds beyond...in much worse repair".

Blacket primarily focused on Victorian Gothic Revival architecture, which influenced James Barnet's design of Sydney University's Andersen Stuart Building.

Such medieval influenced architecture, although partially appropriated to a local context, directly mimic designs of esteemed Cambridge and Oxford universities in England.

[6] In the 1850s, under the direction of Blacket, three stonemasons worked on the clock tower gargoyles: Joseph Popplewell, Edwin Colley, and Barnet.

The infusion of Australian flora and fauna with traditional medieval Neo-Gothic influences is evident in some of the Quadrangle's distinctive gargoyles.

[7] Adjacent to the Quadrangle is the university's Great Hall, which holds an organ designed by Rudolf von Beckerath of Hamburg.

A jacaranda tree was planted in the Quadrangle in 1928 by Professor E. G. Waterhouse, who was also a keen horticulturist and dedicated contributor to the landscape design of the university.

[11] Of the many, three policies are stated in order to maintain and conserve the vegetation and foliage of the university's grounds including the Quadrangle.
