Fort Denison
Fort Denison, part of the Sydney Harbour National Park, is a heritage-listed former penal site and defensive facility occupying a small island located north-east of the Royal Botanic Garden and approximately 1 kilometre (0.62 mi) east of the Opera House in Sydney Harbour, New South Wales, Australia. The island is also known as Mattewanye or Muddawahnyuh in the Eora language, and as Pinchgut Island.
The site contains time gun, navigational aids and tide gauge facilities. Correctional and military facilities were designed by George Barney and built from 1840 to 1862 by William Randle. The property is owned by the Office of Environment & Heritage, an agency of the Government of New South Wales. It was added to the New South Wales State Heritage Register on 2 April 1999. In 1978 the former fortress was listed on the (now defunct) Register of the National Estate, and is currently used as a national park, nature reserve, tourist facility, and as a function space.
Prior to European settlement, the island had the Eora name Mattewanye (sometimes Mallee’wonya).[citation needed]
After the First Fleet arrived in 1788, Governor Phillip and his advocate-general used the name "Rock Island". In 1788, a convict named Thomas Hill was sentenced to a week on bread and water in irons there. The island came to be known as "Pinchgut". Once a 15-metre (49 ft) high or higher sandstone islet, the rock was levelled by convicts under the command of Captain George Barney, the civil engineer for the colony, who quarried it for sandstone to construct nearby Circular Quay.
In late 1796 the Governor had installed a gibbet on Pinchgut. A convict to be hanged and then gibbeted there was Francis Morgan. In 1793, the British transported him to New South Wales for life as punishment for a murder. The authorities in NSW executed Morgan for bashing Simon Raven to death in Sydney on 18 October 1796. On 30 November 1796, Morgan was hanged; following his execution, his body was hung in chains (gibbeting) on Pinchgut. His skeleton was still hanging there four years after his execution. He said to the hangman that the only thing worth mentioning was the superb view of the harbour from his high elevation, and that he was sure there were no waters the world over to compare with it for beauty.
In 1839, two American warships entered the harbour at night and circled Pinchgut Island. Concern with the threat of foreign attack caused the government to review the harbour's inner defences. Barney, who had earlier reported that Sydney's defences were inadequate, recommended that the government establish a fort on Pinchgut Island to help protect Sydney Harbour from attack by foreign vessels. Fortification of the island began in 1841 but was not completed. Construction resumed in 1855 because of fear of a Russian naval attack during the Crimean War, and was completed on 14 November 1857. The newly built fort then took its current name from Sir William Thomas Denison, the Governor of New South Wales from 1855 to 1861.
The fortress features a distinctive Martello tower, the only one ever built in Australia and the last one ever constructed in the British Empire. It was constructed using 8,000 tonnes (7,900 long tons) of sandstone from nearby Kurraba Point, Neutral Bay. The tower's walls are between 3.3–6.7 metres (11–22 ft) thick at the base and 2.7 metres (8 ft 10 in) thick at the top. However, developments in artillery rendered the fort largely obsolete by the time it was completed. The tower itself had quarters for a garrison of 24 soldiers and one officer. Fort Denison's armament included three 8-inch (200 mm) muzzle loaders in the tower, two 10-inch (250 mm) guns, one on a 360-degree traverse on the top of the tower and one in a bastion at the other end of the island, and twelve 32-pound (15 kg) cannons in a battery between the base of the tower and the flanking bastion.
Eventually all the guns were removed, except for the three 8-inch (200 mm) muzzle-loading cannons in the gun room in the tower, which were installed before construction was complete. The passages within the tower are too narrow to permit these to be removed. However, from the beginning the three cannons were of limited utility. The embrasures for the cannons were too small to use the guns effectively and by the time a cannon was loaded the ship it was to fire on would have sailed past. Lastly, the guns' recoil was too powerful for the small room.[citation needed]
