Fort Queenscliff

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. The Fort, which underwent major redevelopment in the late 1870s and 1880s, became the headquarters for an extensive chain of forts around Port Phillip Heads. 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.
