You can’t go far in Ireland without catching a glimpse of a castle. With more than 30,000 castles in the country, it’s almost impossible to see them all. We’ve narrowed the list down to the greatest castles in Ireland so you know which ones to stop by and which ones to roll past.
1. Blarney Castle
Consistently ranked as one of the best places to visit in Ireland, you absolutely cannot miss Blarney Castle. Dating back to 1446, thousands of tourists make their way here each year to kiss the renowned Blarney Stone. Rumor has it if you climb the 10 stories to the top then hang upside down to kiss the stone you’ll be fortunate enough to get the gift of eloquence. Once you’ve kissed the stone and explored the castle be sure to take some time to admire the 60-acre floral garden.
2. Bunratty Castle
The fourth castle to be built on this site, Bunratty Castle sits on a 970 AD ancient Viking trading camp. The castle was opened to the public in 1960, and a tour around the castle shows off art, furniture, and tapestries from the 15th century. You can also take part in a traditional medieval feast, where you’ll be served all types of deliciousness like turkey legs, potato soup, goblets of mulled mead, and fresh bread by women in medieval gowns. For a true medieval experience, Bunratty is one of the best castles to visit in Ireland.
3. Cahir Castle
Cahir Castles is easily one of the best Irish castles.

While you’re exploring the castle, check out the amazing countryside views from the top of Cahir Tower, and catch a 15-minute film that teaches about the function of Ireland’s fortresses.
4. Ashford Castle

After you’ve toured the castle, take your pick of everything from shopping around the museum shop and retail store to exploring the walled Talbot Botanic Gardens or taking a bicycle tour.
6. The Rock of Cashel
Home to an extensive collection of medieval architecture and Celtic art, this enormous compex has everything you could want in a castle experience.

9. Donegal Castle
Located on a bend along the River Eske, the castle was built in 1474 by one of the most powerful Gaelic families in Ireland at the time, the O’Donnells. It was once said to be one of the finest Gaelic castles in Ireland, but because of the Nine Years’ War it was nearly destroyed. Soon after its attempted destruction by the O’Donnells, English Captain Sir Basil Brooke quickly rebuilt the castle in a Jacobean style and today it’s surrounded by a 17th-century boundary wall.

Right near many of Dublin’s best hostels and hotels, it should be a super easy walk to the castle if you’re staying in the city.
11. Birr Castle
Because it’s home to Brendan Parsons, the 7th Earl of Rosse, the castle’s residential areas aren’t always open to the public, but the gardens and grounds are full of beautiful and historic sights.

15. Lismore Castle

Rhododendrons, camellias, magnolias, and spring flowering bulbs bring an amazing beauty to the gardens. Divided into two parts, the upper garden is a 17th-century walled garden that’s Ireland’s oldest formal garden while the lower garden is a more informal 19th-century garden with lawns, trees, and shrubs.

20. Doe Castle
Considered to be the safest and strongest castle of its time, Doe is an amazing sight to see. Built on a peninsula and surrounded by water on three sides, it nearly looks like it’s floating.
