George Strickland Kingston made his mark in the new colony as a civil engineer, architect and surveyor. In 1840 he was commissioned to design Adelaide's new Gaol. The plans he drew up were based on the contemporary American radiating model, used on some gaols in Ireland and England's Pentonville prison.
The first Governor of the Gaol, William Baker Ashton, was born in 1800 and arrived in South Australia in November 1838 with wife, Charlotte, and their three children. He accepted the position as Governor of the original gaol - the 'Stone Jug' - on 1 January 1839. He later became the first Governor of the Adelaide Gaol - a position he held until his death in 1854.
William's disturbed spirit is said to visit the Gaol regularly.
