Mountjoy Prison (), founded as Mountjoy Gaol and nicknamed The Joy, is a medium security men's prison located in Phibsborough in the centre of Dublin, Ireland. The current prison Governor is Edward Mullins. History Mountjoy was designed by Captain Joshua Jebb of the Royal Engineers and opened in 1850. It was based on the design of London's Pentonville Prison also designed by Jebb.
