The Army Museum of Western Australia was established in 1977 and was originally located at Dilhorn House, a 19th-century building located on Bulwer Street, Perth.
The museum was relocated to its current site at the Artillery Barracks site in Burt Street, Fremantle, in 1995.

The Fremantle Artillery Barracks, also known as Victoria Barracks, was acquired by the Commonwealth in 1909 for ₤3,000.
The Artillery Barracks was constructed in two stages between 1910 and 1913 as the base for the Royal Australian Garrison Artillery, who manned the heavy artillery guns guarding the port of Fremantle.
The original concept for the buildings and spaces was designed by Hillson Beasley, the Government Architect at the Public Works Department of Western Australia.
 The barracks are constructed of red brick and limestone in a Federation Free Classical style of architecture and designed to accommodate 120 men and officers of the Artillery Corps, providing protection for the harbour and the hulks with emergency coal supplies for the British Fleet.

The location of the site reflects the prevailing view of Sir Joseph John Talbot Hobbs that potential enemies would mount seaborne rather than aerial attacks.
The Artillery Barracks were designed to service the two batteries at Arthur (Arthur Head) and Forrest (North Fremantle) Forts, as part of the Fremantle Harbour defences prior to World War I.
The first stage of construction in 1910 was a two storey barracks, providing accommodation for 40 men, Orderly Room, Guard Room, Quarter Store, separate Kitchen block and Gymnasium, facing on to the parade ground.
Three years later a second Barracks block, Married Quarters, Officers Quarters and a Hospital (later converted into the Sergeants' Mess)  were completed.
A large grassed area on the northern side of the hill was used for agistment of the horses.

In 1914 with the commencement of World War I, the barracks were then used as hospital wards, firstly for sick recruits of the First Australian Imperial Force, then for the convalescing wounded from the Western Front, a use which continued for a year after the war concluded.

Between the wars a number of working structures, such as sheds and garages were built, and in 1928 a wooden signal tower was constructed to take over from the signal station at Arthur Head.

After World War II, Major General John Whitelaw, took up residence at the Commanding Officer's Quarters, known as Gun House.
This established a tradition for the most senior serving officer to reside at the site; eighteen serving regional commanders have lived there since 1946.
From 1948 onwards the barracks mainly served as a training venue for the Citizen Military Forces, which then became the Australian Army Reserves.

In 1935 the land now occupied by the Army Store was ceded to the Royal Australian Navy, which built its own store in a simple Functionalist style.
In 1956 the timber signal station, on the top of Cantonment Hill, was replaced by a masonry signal station, for use by the Fremantle Harbour Trust Commission.
The signal station operated for only eight years before new grain silos at North Quay partially obscured the view and the signal station was replaced by a facility on top of the Fremantle Port Authority building.
The Cantonment Hill station was then handed back to the Army.
