Castles and forts in Northern Ireland

The castles and forts in the care of the National Trust in Northern Ireland speak of sieges and centuries ceased. The old ruins at Crom help date an historic yew tree while Dunseverick Castle aligns with the footsteps of Saint Patrick himself. As the first property acquired by the National Trust in Northern Ireland, the Rough Fort was constructed in Ireland between the 7th to 9th centuries, while the Old Tower at Castle Ward became Winterfell in the TV series Game of Thrones.
