[3] The structure was re-modelled with a four-stage steeple erected in front of the main block at the expense of the local member of parliament, Henry Cunningham, in 1720.

[3] In 1888, clock faces were added to commemorate the Golden Jubilee of Queen Victoria, an innovation which the historian, Thomas Scott Muir, regarded as having "disfigured" the steeple.

[3] A plaque to commemorate the lives of local service personnel who had died in the First World War was unveiled at the base of the steeple in November 1927.

[11] The building remained the meeting place of the Royal Burgh of Queensbury for much of the first half of the 20th century but ceased to be the local seat of government after a new council chamber was installed at the former Viewforth Hotel further to the southeast along the High Street in 1945.

[12] The complex subsequently served as an events venue with organisations such as the Central Scotland Ballet School renting the auditorium.
