Fort Lytton National Park, located 13 kilometres northeast of Brisbane's CBD, preserves a pentagonal fortress built in 1881 as part of Queensland's 19th-century coastal defence strategy. Designed to protect Brisbane's shipping lanes and harbour from potential enemy raids, the fort exemplifies Victorian-era military engineering with its sophisticated architecture. Heavy armaments were ingeniously concealed behind grassy ramparts and connected by underground passages, while a water-filled moat surrounded the entire structure. From 1881 until the 1930s, Fort Lytton served as Brisbane's primary line of defence and is regarded as the birthplace of Queensland's military history. Abandoned after World War II, the site was established as Queensland's first historic national park in 1990. Today, guided tours led by dedicated volunteers from the Fort Lytton Historical Association provide public access on most Sundays and public holidays, revealing the strategic significance of this well-preserved coastal fortress.
