The castle stands on the site of the 1014 Battle of Clontarf. That battle saw Brian Boru defeat Viking forces and secure Irish rule. A permanent fortification appeared here in the 12th century. Hugh de Lacy granted the land to the Knights Templar, who built the first castle.
After the Templars’ dissolution, the property changed hands several times. In 1640, the Vernon family acquired Clontarf Castle. They kept it in the family for almost 300 years. Over time, the Vernons rebuilt and extended the castle into a grand residence. In the 18th century, they added Georgian windows and elegant interiors. By the early 19th century, the castle had fallen into disrepair. In 1837, architect William Vitruvius Morrison designed a new Gothic Revival structure. That design gave the castle its current romantic appearance. The battlements and turrets you see today date from this period. The Vernons eventually sold the property in the 20th century.
