The Great Hall, or dining hall, is a space with a large wooden roof of collar beams and arched braces, with king post and raking queen posts. Each truss is visually supported by short stone shafts with foliate capitals and corbels in the early 14th century manner, as is the tracery. The formal entry stairs intended to be placed to the south have never been built, and the original eastern wall has been replaced by an open arcade. On the western wall of the Great Hall is the Purcell Window, completed in 1930 by Hardman & Co. Birmingham. The upper windows contain the coats of arms of the universities of Sydney, Oxford (trefoils), Cambridge (trefoils), Paris (left soufflet) and St. John's College (right soufflet). The Great Hall has on display a collection of portraits of past visitors, rectors, fellows, and students, with the most significant portrait being "Archbishop Polding / Gallery oil painting of Archbishop Polding DSB", 1866, by Eugene Montagu Scott (1835–1909), which was originally commissioned for St Mary's Cathedral.
