A bronze plaque commemorates the "Nine O'clock Gun," a naval type twelve pound muzzle loader, cast in 1816 at Woolwich, England, and brought to Vancouver about 1894. It was part of the "Crests of King George III and of the Earl of Mulgrave, Master General of Ordnance." The plaque also mentions gun restoration and preservation efforts by EBGO Industries Ltd., Chester F. Millar, and Hudson's Bay Company.
