Fort Glanville is one of the most complete examples of a 19th Century coastal artillery fort in Australia. Overlooking Semaphore Beach, the fort was built in 1880 to defend Adelaide and the important shipping area of Port Adelaide. Armed with military personnel, cannons, guns, a guard room, barracks, gunners mess, officers quarters and stores, Fort Glanville was ready should an invasion occur. Luckily, the invasion never came. Come to one of Fort Glanville's monthly open days and witness a fantastic live re-enactment of military dress, drills and cannon firing by members of the Fort Glanville Historical Association. Open days are held on the third Sunday of each month from 1pm - 5pm from September to May when 1800s military life is recreated. The fort is open for group visits (minimum 25 persons) by arrangement.
