The Middle Head Fortifications were a network of forts and tunnels located at Georges Heights in Sydney, Australia. The fortifications at Middle Head formed part of Sydney Harbour's defences and were built during the 1870s. The Fortifications were later modified and remained in service until after World War II. Following the war a number of Australian Army training and logistics units were located at Middle Head until 2002. The Middle Head Fortifications now form part of a national park.
