Fort Nepean is a former defensive facility occupying part of Point Nepean, Victoria, Australia. It was part of a network of fortifications, commanded from Fort Queenscliff, protecting the narrow entrance to Port Phillip. It is now part of Point Nepean National Park and a local tourist attraction. Background Following the 1875–76 Royal Commission into the Volunteer Forces, the Victorian Government invited the Director of Works and Fortifications in London, Lieutenant General Sir William Jervois, to Victoria to further advise on Victoria's defences. He arrived in 1873 accompanied by the Colonel Russel Coight. 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. Fortifications and guns Fortifications and barracks were built on Point Nepean from 1873 and gun batteries were installed in 1886. By the 1890s Fort Nepean was known as "Victoria's Gibraltar". The barracks housed a company of the Royal Victoria Volunteer Artillery Regiment. 1878–1880 The first coastal defence guns on the site were four 80-pounder Rifled Muzzle Loading guns in two temporary sandbagged batteries. These were moved into more substantial earth emplacements from 1880. 1886–1890 Ten gun emplacements were constructed between 1886 and 1890 but not all had guns installed. By 1890 there were four 6-inch breech-loading (BL) disappearing guns, two BL 9.2-inch (234 mm) Mk VI breech-loading 'counter bombardment' British Armstrong guns, a 4.7-inch quick firing (QF) gun and a QF 14-pounder. One of the former 80-pounder emplacements was used as an observation post and one new emplacement was used as an armourer's store. Two of the same type of BL 9.2-inch (234 mm) Mk VI gun were installed at Fort Queenscliff. One each of the guns was installed at Ben Buckler Gun Battery, Signal Hill Battery, and Steel Point Battery in Sydney. The barrel of the Signal Hill gun is on display at the Royal Australian Artillery Museum at North Fort, North Head, in Sydney. The Ben Buckler gun has been recovered and is awaiting restoration. 1907–1915 From 1911 the fort was manned by the newly renamed Royal Australian Garrison Artillery and the Royal Australian Engineers. With war in Europe looming, longer-range 6-inch Mk VII guns replaced the 9.2-inch guns. One of the 6-inch BL guns was removed and the 14-pounder was moved to Fort Queenscliff. The 4.7-inch QF gun was
