Built between 1207 and 1213 by William Marshal, Earl of Pembroke, on the banks of the River Barrow, Carlow Castle was once among the finest Norman fortresses in Ireland. Most of the structure was destroyed in 1814 when a doctor attempted to convert it into an asylum and used explosives to reduce its wall thickness, leaving only a fragment of two towers standing today.
