Fort Denison – Muddawahnyuh is a significant colonial-era fort in Sydney Harbour. Known as 'Mattewanya' to traditional owners, a 'Pinchgut' to convicts and colonists, it was originally a rocky outcrop before the Colonial Government fortified the island in the 1840s, with later additions including the most complete Martello Tower in the world. The fort has been a tourist attraction since the 1940s and was added to Sydney Harbour National Park in 1995.
Fort Denison – Muddawahnyuh is currently closed to visitors, allowing for significant conservation and repair works to the Barracks building and seawalls. The island's existing 1940s-era timber wharf is being replaced with a new modern, safe wharf that complies with accessibility standards established under the Disability Discrimination Act. The new wharf allows people with mobility issues to safely visit Fort Denison for the first time in the island's 170-year history.
This project is being delivered as part of the largest visitor infrastructure program in national park history.
