It’s eerie that a place of such amazing beauty and tranquillity was once the scene of hard, unrelenting convict labour. The peaceful site, overlooking the shallow waters of Ironstone Bay, is now largely in ruins. Parts of the penitentiary, underground cells, and mine shaft remain, while the history of coal mining and confinement are revealed via subtle interpretation signs. These are strewn like blocks around the site, making the easy walk ideal for slow discovery. Pack a picnic, including drinking water, to allow time to relax and ponder the site’s stories.
An outcrop of coal was discovered at Plunkett Point by surveyors in 1833 and immediate plans were made by the government to exploit the area to provide a local supply of coal for the colony. The Plunkett Point mine was the first operational mine in Tasmania.
In 1839 there were 150 prisoners and a detachment of 29 officers stationed at the mines. Large stone barracks which housed up to 170 prisoners, as well as the chapel, bakehouse and store had been erected. Today, they form imposing sandstone ruins. On the hillside above were comfortable quarters for the commanding officer, surgeon and other officials. Remains of some of these can also still be seen. Carts ran along rail and tram roads to the jetties for loading.
Four solitary cells were constructed deep in the underground workings to punish those who committed further crimes at the mines.
By 1847 the main shaft was down over 300 feet with an extensive system of subterranean tunnels and caverns. The work of extracting the coal was carried out by convicts in two eight hour shifts. The men had to extract 25 tons in each shift to reach the day's quota.
The coal mines were subsequently closed by the government in 1848 on both 'moral and financial grounds'.
The Coal Mines Historic Site is one of 11 historic sites that together form the Australian Convict Sites World Heritage Property.
This walk is managed by Port Arthur Historic Site.
