One of the most extraordinary things to do in Ireland is visit some of the centuries-old castles that accent the landscape throughout the country. Your castle options are vast, from the 13th-century Dublin Castle in the heart of the bustling capital city to the ancient Trim Castle, one of the largest and most storied fortresses on the Emerald Isle and the backdrop for the movie Braveheart.

You can dress up like a character from the show Game of Thrones and shoot arrows in the courtyard at the Castle Ward or walk through the protected ruins of Dunamase Castle, which towers above the countryside in eastern Ireland.

Ireland has so many castles because throughout the centuries, local and regional rulers built fortresses to protect their land and belongings. Their castle dwellings represented wealth and power.

Castles were built at different periods, marking significant milestones in Irish history, from the medieval Norman and Viking periods to the English invasions. Whether you want to stay in a castle or just explore one for the day, you should plot your destinations before you arrive. For ideas, see our list of the top castles in Ireland.

1. Dublin Castle

One of the most significant symbols of power in Ireland is Dublin Castle. This 13th-century castle, which is more of a multi-building complex, was built on a Viking settlement. The castle served as the government complex for the English then British rule for centuries and now serves as a main tourist destination.

Some of the castle highlights include extensive decorative arts in the form of formal portraits of rulers and royalty, as well as period furniture. Be sure to visit The Chapel Royal, a Gothic Revival chapel, which has been at Dublin Castle since 1242, and the castle gardens that have been here since the early 17th century, featuring the Dubh Linn Garden, where patterns of sea serpents are cut into the lawn.

Beneath the castle, you can see ongoing excavations of Viking defenses that have been preserved. You can even go down steps to see the original moat.

For a castle worthy of bragging rights after your vacation, the Trim Castle is a must-visit. This is where Mel Gibson filmed the movie Braveheart, so you will likely recognize the iconic features of this powerful Norman Irish fortress. Construction started on the Trim Castle in 1176 and took 30 years to complete.

This massive structure has a 20-sided tower, masterful curtain wall, and moat. It is the largest Anglo-Norman castle in Ireland and has also served as a prison and private home over the centuries.

Now, it is a popular tourist attraction and well worth your time to visit. You can only take a guided tour of the castle, but you can explore the riverside grounds on your own. You can also plan a stay at the Trim Castle Hotel and live like royalty during your trip.

3. Dunluce Castle

If castle mystery is more your speed then the coastal Dunluce Castle in Northern Ireland should top your list. The medieval castle sits on a clifftop along the remote northern coast. The ruins on the site are said to be haunted by the ghost of a woman who died there, and there are mythical tales about fairies and fierce battles that took place on the site.

The Dunluce Castle was built as a family home in the 1500s and served as the inspiration for author C.S. Lewis, who used it to create his Cair Paravel castle in The Chronicles of Narnia.

The site is now under the guardianship of the Northern Irish Environment Agency. These are great ruins to explore, but a stop at the information center for some history and information before you set out will help in your understanding of the site.

The Bunratty Castle is one of the best castles for bringing the medieval times to life. The castle was once part of a Viking trading camp in 970. It has been beautifully restored to its mostly original condition and houses one of the most extensive collections of medieval furniture in Ireland.

There is a Folk Park on the grounds, which is a 19th-century living village, with 30 buildings that imitate what life in Ireland was like in the 1800s. The village is nice, especially for children, who can wander through the recreated farmhouses and village streets and buildings with a backdrop of Irish music.

One of the most engaging experience at the Bunratty Castle is the medieval banquet that you can take part in for an evening of indulgent food, dance, and music inside the castle. You can stay at the Bunratty Castle Hotel if you want to make several days out of your visit to the area.

For Game of Thrones fans, the Castle Ward is an unforgettable experience. The 18th-century castle is the main filming location for the show. An exciting way to enjoy a visit to Castle Ward is to take part in a medieval banquet or sign up for the ClearSky Adventures on-site, which lets you try on Game of Thrones costumes with experts, who teach you how to shoot arrows in the courtyard.

Non-Game of Thrones visitors will enjoy the unusual architecture of the castle. When the castle was built for Lord Bangor and his wife, they could not agree on a structural style, so they compromised by building one side in Gothic architecture for him and the other in Palladian geometry to suit her. The Castle Ward is one of the most unique in Ireland.

9. Dunamase Castle

12. Blarney Castle

You have likely heard of the Blarney Stone in Ireland and the luck bestowed upon those who kiss it – a tradition that goes back more than 200 years. The Blarney Stone is just one of the reasons to visit Blarney Castle.

Be advised that if you plan to venture to the top of the tower to kiss the Blarney stone, lines will likely be long on busy days and can take several hours. That can also mean standing in tight stone stairways for long periods of time, so you will want to check the lines for that first as you plan your visit.

This is actually the third castle on this site, built in 1446. The first castle, made of wood, and the second castle, made of stone, were demolished over time and replaced by Blarney Castle, which welcomes visitors today.

Besides touring the castle and kissing the Blarney Stone, be sure to see the unusual gardens, which include a fern garden; woodlands; and a Poison Garden with plants that are so toxic, they have to be kept behind protective structures.

13. Kylemore Castle

One of the most impressive castles in Ireland is in the northwest in Connemara, overlooking Lough Pollacappul. The castle sits on more than 15,000 acres of land, with stunning gardens and a classically Victorian walled garden.

The castle was built in 1871 as a gift to the wife of an English doctor. The estate changed hands several times, eventually becoming an Abbey in 1920, when it was purchased by the Irish Benedictine. Although you can explore the castle grounds on your own, first-time visitors should take a guided tour to capture the full history and significance of the castle.

Some of the things to include on your Kylemore Castle must-experience list are: going inside to see the restored rooms and artifacts from previous owners, walking through the six acres of walled gardens accented with fruit trees and flower and herb gardens, and visiting the Neo-Gothic church on the estate.

Location: Kylemore Abbey, Pollacappul, Connemara, Co. Galway, Ireland

14. Kilkenny Castle

Kilkenny Castle in southeast Ireland is a 12th-century castle overlooking the River Nore. The castle holds an important piece of Ireland's history following the Norman conquest. Kilkenny Castle was privately owned for hundreds of years until the mid-1960s, when it became the property of the city of Kilkenny.

Today, it remains one of the finest examples of castle architecture in the country. You can walk the stairs below the Rose Garden Terrace to the castle's medieval foundation, and see how the structure winds through the ground floor. Be sure to take note of the circular room beneath the West Tower, which gives insight into the methods used during the castle's 13th-century construction. It seems labor intensive compared to what is used today with technology and machines.

Inside the castle, you can see a cantilevered staircase, a fireplace made entirely of marble, and a stunning grand entrance corridor that adjoins the east and west wings. The castle's collection of 17th-century tapestries is also worth a visit. You will want to plan a significant amount of time to walk the grounds, which feature a park and gardens.

The Gothic Revival architecture of Slane Castle in County Meath is one of the reasons it is a standout among castles in Ireland. It was built in the late 1700s in the Boyne Valley by a family committed to improving the Village of Slane.

Guided tours of the castle are offered and recommended as a way to learn about the history of the castle, the significance of its architecture, and the people who lived in the castle throughout the centuries. The estate sits on more than 1,500 acres of park green space, which is nice to stroll, or you can hike up the Hill of Slane to find out about its connection to St. Patrick.

The Slane Castle has also been transformed into a concert venue, so that is a unique way to enjoy the estate if there is an event scheduled during your stay. There are overnight accommodations at Slane Castle available at the organic farm located on the estate.
