Port Arthur

Inlet of the Tasman Sea on the south coast of the Tasman Peninsula, Tasmania, Australia. It is known for the penal settlement established there in 1830 by Sir George Arthur, then lieutenant governor, who attempted to centralize the several settlements in Van Diemen's Land (Tasmania). A model reformatory for boys also existed from 1835 to 1849 at Point Puer, a rocky headland in the inlet.
