Trial Bay Gaol, Prison ruins in Arakoon National Park, Australia

Trial Bay Gaol is a ruined prison complex on Laggers Point in Arakoon National Park, built of yellow sandstone from 1877. Its rectangular blocks form a shallow gable above a tall arched gateway with an iron grille, flanked by smaller barred windows. Inside, four long cell blocks are arranged in a V behind the mess hall, with the gatehouse now housing a museum.

Construction of the gaol began in 1877, funded by £10,000 set aside for a breakwater and a prison to house the labour force. Prisoners built the breakwater from 1889, but the river changed course after about 300 metres, making the project obsolete; the gaol closed in 1903. From August 1915 to 1918 it held German and Austrian internees, up to 580 at its peak.

The site served as an internment camp during World War I, housing people of German descent under government orders. This dual purpose as a prison and wartime facility shaped its meaning in the community for generations.

The site is accessible daily to visitors, with an on-site museum displaying prisoner belongings and historical photographs. Walking paths lead through the ruins, and visitors should be prepared for changing coastal weather.

From the guard tower, visitors can watch whales pass along the coast during their seasonal migration. This unexpected wildlife experience adds a natural element to a historical site.
