Fort Queenscliff, in Victoria, Australia, dates from 1860 when an open battery was constructed on Shortland's Bluff to defend the entrance to Port Phillip.
Its garrison included volunteer artillery, engineers, infantry and naval militia, and it was manned as a coastal defence installation continuously from 1883 to 1946.
The other fortifications and armaments around the Heads were completed by 1891, and together made Port Phillip one of the most heavily defended harbours in the British Empire.
It occupies an area of 6.7 hectares on high ground known as Shortland's Bluff and overlooks the shipping lanes leading to Melbourne and Geelong.
The Fort is a superb example of the defences that existed around the coastline of Australia from colonial times through to the end of the Second World War.
Continuing prosperity during the 1880s and 1890s led to the building of more guest houses and two further paddle steamers, the Hygeia and the Weeroona, which serviced the tourist trade.
The attraction of the town for the holiday-maker came from its unique blend of military and civilian activities, the picturesque fishing fleet and the ever-changing seascape.
The defences at Queenscliff and elsewhere around Port Phillip were developed in the second half of the 19th century, to protect Melbourne and its outlying settlements from invasion by hostile foreign powers.
Their joint report recommended that the basic defences for the Colony should be concentrated on the Heads, and consist of fortifications at the entrance to the Bay and on the shoals between the main shipping channels.
By design Fort Queenscliff became the command centre for the Heads defences, probably because of its strategic location and established telegraph links with Melbourne.
Built from sandstone quarried at Point King, this sea wall was positioned directly east of the site of the original upper lighthouse.
It was designed to strengthen the cliff face and allow the positioning of heavy-calibre guns in an elevated location, right on the edge of the Bluff.
Designed in a quatrefoil pattern, it accommodated four 68-pound muzzle-loading cannons which were manned by the Volunteer Artillery, made up of local residents.
In 1870, as the last detachment of British troops left Victoria, the debate on the Colony's defences remained unresolved and the future of the Queenscliff battery was by no means certain.
An array of support facilities were also erected, including a drill hall (1882), barracks (1885), assorted sheds and stores, a guard house (1883), and a separate cell block (1887).
With the erection of the wall, the civilian presence in the Fort came to a virtual end, and by 1887 both the lighthouse keepers' quarters and the post and telegraph office were turned over to military use.
Around 1915, substantial development occurred along the northern boundary of the parade ground which involved the removal of an old shrapnel mound from behind the wall and the erection of a number of timber barracks and mess buildings.
Though over two hundred military units have been associated with Fort Queenscliff since the 1860s, two major groups of permanent soldiers have been based here: the coastal gunners of the artillery and their technical support provided by the sappers of the fortress engineers.
One incident in the early 1900s told how for weeks on end there was not 'pudding' until constant demands resulted in a dessert made from boiled cabbage scraps.
As the site of the first lighthouse and the first pilots' hut, it contained the earliest major navigational aid to ships entering Port Phillip.
Subsequently, as the location of the telegraph station, it provided Melbourne with vital overseas information long before incoming ships reached their berths, and was the civil centre of the early township.
In terms of military history it is the site of the first substantial attempt to defend the entry to Port Phillip, and subsequently was the centre of the major fortification of the Heads.
The Fort is the tangible remains of part of this system of defences, retaining its nineteenth century layout largely intact, and illustrating the rapid evolution of military engineering during this period.
Finally, its significance relates to the fact that the site on which it is built has been utilised for military purposes for over one hundred and twenty years, and is presently still occupied by the Australian Army.
Although not utilised in the manner in which it was originally designed, this continued occupation has been instrumental in maintaining the Fort as an example of living history as opposed to being a museum piece.
Today the Fort Queenscliff Museum receives support from a wide range of government and private organisations and many interested individuals.
Accordingly, the Fort Queenscliff Museum has sought to create an environment that evokes public interest and reminds visitors of our early military history.
