The Wicklow Gaol was where those Irish patriots involved in the 1798 rebellion were held prior to transportation to Australia. Inmates included prominent rebels such as "General" Joseph Holt and Michael Dwyer.
The first Irish convicts were transported to the Sydney colony in 1791 and prisoners were sent there from Wicklow Gaol from 1796 until the 1850s. You can find more history on the Wicklow Gaol website.
