 Fort Glanville Conservation Park is one of South Australia 's most important heritage sites . It is the premier site in the state , and possibly Australia , for showcasing colonial era defences and fortifications . The fort is listed on both the South Australian Heritage Register and the National Trust 's classified list . It is considered significant , in national historical military terms , for its association with Jervois and Scratchley ; both leading British defence experts who influenced Australian defence thinking in the late 19th century . The fort was very well constructed with high quality materials ; facts that have been noted as contributing to its preservation . The fort is largely intact and in original condition and is , along with Bluff Battery in Hobart , the best preserved Jervois @-@ Scratchley designed fort in Australia . It is the only Australian colonial fort to still have all of its original armament , and the only to have a regular living history program . Its companion Fort Largs does survive but in greatly modified condition , converted for use as the South Australia Police academy . The fort retains its original armament ; armament that is both rare in Australia and worldwide .
