The Wills Memorial Building was commissioned in 1912 by
George Alfred Wills and
Henry Herbert Wills, the magnates of the Bristol tobacco company
W. D. & H. O. Wills, in honour of their father, Henry Overton Wills III, benefactor and first Chancellor of the University who donated £100,000 to the University. Sir George Oatley, who also worked on a number of other buildings for the University,
 was chosen as architect and told to "build to last". He produced a design in the
Perpendicular Gothic style, to evoke the famous university buildings of
Cambridge. The building was funded through the fortunes which the Wills family made through tobacco
 Oatley later claimed that his inspiration for the building came from a dream where he saw a tower on a hill with shields around it.
Construction was started in 1915 but was halted in 1916 due to the continuation of
World War I.
 Building was restarted in 1919, and the Wills Memorial Building was finally opened on 9 June 1925 by
King George V and
 having cost a total of £501,566 19s 10d. The building was opened with a Royal Salute of 21 chimes from 'Great George', the nine and a half ton bell within the octagonal belfry of the tower, which is tolled on the death of a monarch or chancellor.
 To celebrate the Centenary of the University receiving its
charter, 'Great George' was rung, along with bells in Bristol's other churches, just as they did in May 1909 when King Edward VII granted the University its Royal Charter to grant degrees.
 Oatley received a
knighthood that same year in recognition of his work on the building.
In 1940, during the
Bristol Blitz of
World War II, the Great Hall with its
Hammerbeam roof was badly damaged by a German bomb-blast. It was restored in the 1960s to Oatley's original design:
 at the same time the adjoining wing was enlarged by Ralph Brentnall.
