What are the Best Castles to Visit in Ireland?

While many people visit Ireland for its culture, its beautiful scenery, and its friendly people, it’s often Ireland’s history that leaves the most lasting impression. And one thing we’ve noticed here at Overland Ireland is that people visiting from North America are especially impressed by our castles. Given that there are over 30,000 castles and castle ruins on our fair island, it’s easy to see why guests often talk about the castles as one of their main highlights. For anyone planning a trip, consider one of our small group tours of Ireland, we thought we’d write a quick rundown of some of our favourite Irish castles. We’ll throw in some fan favourites and some hidden gems and we hope we can inspire one or two readers to add some castles to their next Irish adventure!

Kylemore Castle

Kylemore Castle

This huge castle was built on the foot of Druchruach Mountain by Mitchell Henry in 1871 as the most over-the-top present in history for his wife. While this castle isn’t nearly as old or as historically significant as the others on this list, it looks like a Disney palace and there is also a cathedral and mausoleum to explore. Gorgeous castle views? Check. Gothic cathedral? Check. Fascinating Victorian mausoleum? Check!

The Rock of Cashel

Rock of Cashel

The Rock of Cashel is in county Tipperary and it’s a must-see that you’ll find on many people’s Ireland bucket lists. This is not one of those instances where a big attraction is overrated; it absolutely is worth a visit. Legend states that the castle was built on the spot where St Patrick converted the King of Munster to Christianity in the 5th century. However, the castle wasn’t built until the 12th century. Given how long ago the castle and the surrounding buildings were built, the Rock of Cashel is in remarkable condition. There’s so much to see and learn about here, but we’ll leave most of it for your tour. If you definitely want to see this ancient castle, you may like to book our Ultimate Ireland Tour as the Rock of Cashel is one of the stops!

Dunluce Castle

Dunluce Castle

This medieval castle ruin can wow even the most seasoned traveller. Dunluce sits on the Antrim Coast, on the northern coast of Northern Ireland, and there is a free guided tour that takes place every day. While Dunluce Castle has clearly seen better days, it was built back in the 1200s, so overall, it is in good condition. This ruin was featured as the House Greyjoy’s castle in Game of Thrones and it inspired C.S. Lewis when he wrote the Chronicles of Narnia.

Blarney Castle

Blarney Castle

This is perhaps the most famous castle in Ireland, and there is good reason for this: the myths and legends surrounding the Blarney Stone capture the imagination of all who hear them. The fact is that this beautiful castle would be worth visiting even if it didn’t have a mythical stone that grants visitors the gift of eloquence and flattery. The castle looks especially impressive as it rises above the trees and lush green landscape surrounding it. And, given that it was built in 1446, it is in fantastic condition. You can visit Blarney Castle on our Emerald Explorer 7-day Ireland Tour.

Dunguaire Castle

Dunguaire Castle

Another somewhat hidden gem, Dunguaire Castle can be found in Co. Galway, right on Galway Bay. This fortified tower is visible from miles around due to the water and a sparse number of trees. The tower cuts an imposing, impressive silhouette on the landscape and it’s even more striking when you see it up close. Dunguaire Castle was built in the early 16th Century, but it is in remarkable condition due to a faithful restoration carried out between the 1920s and the 50s.

Bunratty Castle

Bunratty Castle

You’ll find Bunratty Castle in Co. Clare, and we think it more than earns its place on our list! Just look at it! While Bunratty Castle was built in the 15th Century, a lot of time, work, and money went into restoring it in the 1960s. This is why it is the most intact and visually impressive structure on our list. It’s important to remember that while it was restored in the 60s, a lot of care was taken to ensure that it looks and feels just like it would have in the 15th and 16th centuries. So, if you want to experience what it would have been like to walk through a castle 500-600 years ago, then Bunratty Castle should be at the top of your list.

Ashford Castle

Overlooking Lough Corrib, Ashford Castle in County Mayo has been converted into a hotel so opulent it was reportedly chosen by Harry and Meghan for their honeymoon. The castle is only accessible for hotel guests but we had to mention it here, and we include a stay here on our Luxury 8-Day Ireland Tour. 

Activities at Ashford include falconry, boat trips, archery, an award-winning spa and even a Lego butler for younger guests!

Ballynahinch Castle

Another of our hand-picked castle stays is Ballynahinch Castle, set in the ruggedly beautiful Connemara landscape. This is our choice of accommodation for our 10-day self-drive Ireland tour

Even if you choose not to stay, the restaurants offer food fit for royalty, perfect after a day exploring the surrounding Connemara National Park.

Kilkenny Castle

Kilkenny is a magnificent example of a medieval fortress with Norman and Gothic styles incorporated into the architecture. The rose gardens here are particularly special, offering a scented oasis in the heart of the city. 

Kilkenny’s Butler Gallery is a free art gallery and museum with an extensive permanent collection and vibrant exhibitions. 

Ross Castle

County Kerry’s Ross Castle has pride of place in several of our tours, and for good reason. The guided tours here provide a real glimpse into medieval life. Ross Castle is located on the shores of the breathtakingly beautiful Lough Leane and is surrounded by mountains.

Explore the lake by boat and learn about the area’s flora, fauna, and folklore. But beware! Legend has it that the castle’s founder keeps watch over his castle from the bottom of the lough and rises every seven years, accompanied by a group of ghostly musicians. You have been warned!

Dublin Castle

To end on a contemporary note, Dublin Castle started life as a medieval fortress and now inaugurates Ireland’s presidents. Visitors can tour the castle and its beautifully manicured gardens or attend one of the many vibrant cultural events held within its walls.

Dublin Castle is also home to the Chester Beatty Library, which houses a remarkable collection of rare books and manuscripts. Highlights include ancient Egyptian papyrus manuscripts, Japanese woodblocks, and several illuminated manuscripts, including the Qur’an, Bible, and Buddhist texts.
