The 12 Best and Most Breathtaking Castles to Visit in Ireland - IL

What does the word castle mean to you? Cinderella’s Castle may quickly spring to mind; the impossibly beautiful Neuschwanstein castle built on a rocky crag in the German Alps, or it might be England’s stately Windsor Castle, for lavish ceremonies and royal weddings. Even a dreamy lakeside hotel, and for others, its battlements, baileys, and keeps, with knights in shining armor.

For the fortunate few, actor Jeremy Irons and musician Enya among them, ‘castle’ simply means home. Whatever emotion the word might evoke for you, you’re sure to find a match to the memory, because this small island has a staggering 30,000 castles, more than anywhere else in the world.

Here are 12 great Irish castles, ranked in must-see order:

1. Ashford Castle—The Best of the Best

Ask a local where to find Ashford Castle and some would say Mayo, others might say Galway. In a delightful irony, both are correct. The castle is located in Co. Galway while the tea rooms, lodge, and much of the extensive grounds are in Co. Mayo. Furthermore, in another peculiar twist, you cannot reach the castle—which is in Co. Galway—without traveling through Co. Mayo.

This remarkable 800-year-old castle, widely recognized as Ireland’s top castle and once home to the Guinness family, is exceptional in every sense. Set in 350-acres of woodland on the shores of Lough Corrib, this historic multi-award-winning castle has been voted ‘Best Hotel in the World.’

Watch hawks soar at Ireland’s first School of Falconry, enjoy a round of golf on a course designed by Eddie Hackett, and restore inner peace and harmony at the state-of-the-art spa. Take a lake cruise to explore the stunning scenery and surrounding islands or try your hand at archery and clay shooting.

Extraordinary dining experiences await in the Dungeon, the George V Restaurant, and in the wine cellars beneath the castle. In the evening retreat to the Billiards Room, watch a movie in the 32-seater cinema, or try one of the 60 Irish whiskies in The Prince of Wales Bar.

Part of the Red Carnation Hotel Collection and a member of Leading Hotels of the World, Ashford Castle is the only hotel in Ireland to have earned a 2021 5-Star Forbes Travel Guide Ranking for the second year in a row.

Most of the buildings date from the 12th and 13th centuries whilst the castle is from the 15th century.
