Ruthin Gaol - United Kingdom Ruthin's first gaol is thought to have been located in the Old Court House of the Lordship of Ruthin. This half-timbered building, now the National Westminster Bank, was built about 1404 following Owain Glyndwr's attack on the town which left very few, if any, houses standing.
Baronial, manorial and other courts were held; prisoners being detained in cells below the magnificent beamed court room. Richard Gwyn, a Welsh Catholic martyr, spent the last four years of his life imprisoned in the building before his execution at Wrexham in 1584.
