query: When was the Fort Glanville Conservation Park established?
passage: Fort Glanville Conservation Park
Construction of the fort began in 1878. It was officially opened in October 1880 and completed by 1882. Due to changes in the Port River and shipping movements, Fort Largs surpassed it for strategic importance by 1890. By the close of the 19th century, the fort was largely unused and had no defence significance. It was briefly used for military purposes during World War I and World War II, though not for its original defensive role. For much of the 20th century the area was put to a variety of uses including accommodation, a caravan park and a boy scout campsite. After coming into state government hands in 1951 it was declared as a conservation park and is now managed by the Department of Environment, Water and Natural Resources (DEWNR); preserving and showcasing its historic value. The fort and surrounds occupy the northern half of the 5-hectare (12-acre) conservation park, the southern half is a caravan park. The fort is a lunette shaped defensible battery that was supported by land forces for self-defence. When constructed it was seen as state of the art, incorporating powerful and modern weapons. Its main armament is two rifled muzzle-loading (RML) 10inch 20 ton guns backed up by two RML 64 pounder 64 cwt guns, both rare in their particular configuration. The fort retains its original 19th century cannons and three have been restored to working condition.
