20 Beautiful Castles in Ireland to Inspire Your Next Trip

"Built in the 13th century on a site that once held a Viking settlement and featuring a medieval tower with walls up to nearly 16 feet thick, this complex now serves as a government site and tourist attraction a short walk from Trinity College. Visitors can take self-guided visits and guided tours of the Viking-era excavation site, Chapel Royal, state apartments, undercroft, and heritage center, and enjoy the Castle Gardens, enclosed by wrought-iron gates with Celtic-inspired spirals." - Patricia Doherty Patricia Doherty Patricia Doherty is a writer who specializes in covering destinations, resorts, and cruises for Travel + Leisure and other publications.
