This Museum was first opened in June 1984 at the Middlesex County Courthouse in London, Ontario. The Museum now resides at 1 Dundas Street, just down the hill from the courthouse. The building that houses the Museum was originally a working-class family home built circa 1880. The home survived the industrial redevelopment of the area that occurred in the early 20th century, as well as the flood of 1937. Eventually, the owners of the home sold it to the city when the municipal government promised it would remain intact as a heritage site.
The Museum is dedicated to the 1st Hussars, a cavalry regiment that originated in London and St. Thomas in 1856. Soldiers of the 1st Hussars participated in the Fenian Raids (1866), the Second Boer War (1899-1902), the First World War (1914-1918), the Second World War (1939-1945), the Korean War (1950-1953), several UN Peacekeeping missions (1975 – Present), and the War in Afghanistan (2001-2014).
