What remains of Ferns Castle, County Wexford. It is believed to have been constructed in the mid-1220s by William Marshal, second Earl of Pembroke. The family is said to have suffered from a curse placed on it by Ailbe Ua Maíl Mhuaidh, Bishop of Ferns after the first Earl of Pembroke had seized some of his property. The bishop declared that the male line of the Marshals should die out, as indeed it did as all five sons of the first earl failed to leave behind an heir. The fate of Ferns Castle was not much better: during the Confederate Wars, it was blown up in 1641 by Sir Charles Coote (future Earl of Mountrath) to prevent the building falling into his opponents’ hands. Only one of the original four corner towers survives and large sections of the walls are entirely lost, but enough survives to give an idea of how it must have looked.
