In 1870-72, John Marius Wilson's Imperial Gazetteer of England and Wales described Garrison Side like this:
GARRISON-SIDE, an extra parochial tract in the country part of Hull, E. R. Yorkshire; 1 mile N of Hull. Real property, £4, 814. Pop., 160.
The location is that of the former citadel of Hull, which various sources make clear was the area covered by Garrison Side extra-parochial area.
Garrison Side is now part of Kingston upon Hull district. Click here for graphs and data of how Kingston upon Hull has changed over two centuries. For statistics about Garrison Side itself, go to Units and Statistics.
