History of Fort Denison

Fort Denison Sydney Harbour

Fort Denison, Sydney Harbour © Sydney Online Pty Ltd


Fort Denison, which can be seen from Mrs Macquaries Seat, was used in the early days of settlement as a place of punishment and confinement for the convict population. During the mid 19th century a fort was built on the island to protect Sydney Harbour.


Fort Denison is now a tourist destination and is open seven days a week for lunch at the cafe, for picnics or for a leisurely walk around the island taking in the sights.


If you want to do it a little more formally then join a tour group. There are two tours daily to Fort Denison and tours can be booked by visiting the Sydney Harbour National Park Information Centre, located in Cadmans Cottage at The Rocks or by ringing +61 2 9253 0888


However you do it make sure to take in the Martello Tower museum for their collection of colonial artefacts.

Selected Hop-On Hop-Off Cruises stop at Fort Denison. Entrance Fees apply.
