Tours & Museum

Fort Denison is open every day for visitors to discover Sydney’s maritime and colonial history and explore the historical landmark and its features, such as the distinctive Martello Tower – the only one of its kind to be built in Australia. You can even experience the firing of the 1 o’clock cannon.

Visitors can wander around the fort at their leisure on a self-guided tour, or take a guided tour of the island and its museum, or take a trip up the iconic Martello Tower.
