11 Stunning castles in Ireland you need to visit

Ireland's castles are more than historical landmarks—they're doorways to another era. With around 30,000 castles and ruins scattered across the countryside, each stands as a testament to Ireland's rich past.  

So how do you choose where to go? From ancient strongholds steeped in myth to grand estates that offer luxury escapes, these must-visit castles promise to immerse you in the captivating charm of Ireland. 

Blarney Castle 

Plan your visit to Cork, Ireland, and discover Blarney Castle, one of the country's most iconic and cherished landmarks. This impressive tower house is a marvel of medieval architecture, with walls measuring 18 feet thick at the base, tapering as they rise.  

At the heart of the castle's allure lies the legendary Blarney Stone. According to folklore, those who kiss the stone are granted the "gift of gab"—the ability to speak with eloquence and charm.  

But earning this gift requires more than just a kiss. Visitors must climb the stone staircase to the castle's summit, lean backward over a protective barrier, and grip iron bars to kiss the stone upside down. 

Kilkenny Castle

Commanding over the River Nore, this castle is the jewel in the crown of the city of Kilkenny. Inside, luxurious rooms remodelled during the Victorian Era are filled with antiques collected over the centuries.  

Take a guided or self-guided tour of one of Ireland's longest-inhabited buildings. Surrounding the castle are gardens, including a terraced rose garden, woodland and lake. Both the grounds and castle are open year-round for exploration. 

Rock of Cashel  

Dramatically set atop a limestone hill in the Golden Vale is a medieval castle complex of monuments and ruins. This stunning cluster of historic buildings includes a round tower, a high cross, an abbey, a Gothic cathedral and a Romanesque chapel.  

In Cormac's Chapel, you'll find Ireland's only remaining Romanesque frescos. Legend has it that the Rock of Cashel is where St. Patrick came and converted King Aenghus to Christianity. Today, you can still see St. Patrick's Cross as one of the monuments.  

Dublin Castle

Chances are that your Irish vacation will include spending time in the capital city of Dublin. You'll find Dublin Castle in the city's historic heart, between Trinity College, Christ Church Cathedral and the Temple Bar area.  

Built on a former Viking settlement, the building has acted as a military fortress, prison and court of law, and English and British administration headquarters.  

Today, the castle is a government complex with state apartments, Chapel Royal, and a restaurant open to visitors. There are stunning antique paintings, sculptures, furniture, tapestries, stained glass and textiles to admire.  

Dunluce Castle

Living through some of Ireland's most violent years, Dunluce Castle was inhabited at different times by the feuding McQuillan and MacDonnell clans. With a history littered with bloody fights, the drama of the castle ruins' cliffside location provides both a ghostly and romantic atmosphere.  

These picturesque ruins sit on the wild northern coast in County Antrim as waves crash below. Explore the two sections of castle ruins connected by a stone bridge, navigating rocky, grass-covered areas that were once a brewery, kitchen, stables, a fortified gatehouse, lodgings and other rooms.  

Glenarm Castle

Glenarm Castle, the crown jewel of a stunning estate, is rich in history and charm waiting to be discovered. As the private residence of the Earl and Countess of Antrim and their family, the castle opens its doors to guided tours on select days throughout the year.  

The estate offers much more than the castle itself. Stroll through the tranquil beauty of the Walled Garden, a true botanical sanctuary. Dive into the castle's fascinating history and family heritage at the Heritage Centre. Marvel at a collection of rare vehicles in The Coach House Museum and indulge in a delicious lunch at the tearoom, followed by a sweet treat from The Milk Parlour. 

Blackrock Castle

Blackrock Castle, the oldest surviving building still in use in Cork, has a rich and varied history. Originally built as a river defence for the city, it has also served as a lighthouse, an Admiralty Court, a signalling station, and a gun battery. Today, visitors can explore its fascinating 400-year story on a guided tour, from its beginnings as a fortress to its transformation into a modern observatory, complete with a cutting-edge telescope installed on the tower. 

Your admission includes access to the award-winning MTU Blackrock Castle Observatory Science Centre, where you can explore captivating exhibits like "Ireland in Space" and participate in events or workshops that bring the wonders of the night sky to life. If you're looking for a bite to eat, the Castle Café offers delicious meals in a setting steeped in historic charm, with no entry fee required to visit the café. 

Dromoland Castle  

Indulge in the royal treatment with a luxurious stay at Dromoland Castle. Nestled within 500 acres of serene woodland, the estate boasts scenic walking trails, a tranquil lake, ornamental gardens, and majestic, ancient trees. This enchanting retreat seamlessly blends historic charm with modern comforts, offering every guest an array of on-site activities.  

Tee off on the championship 18-hole golf course, unwind in the castle's spa sanctuary, or join a yoga class. For the adventurous, rent a stand-up paddleboard or immerse yourself in traditional pursuits like archery, falconry, and clay shooting. Dining at Dromoland is equally exquisite, with options ranging from fine cuisine to the cherished tradition of Mrs. White's Afternoon Tea. 

Birr Castle 

Set within 120 acres of ancient parklands and meticulously maintained formal gardens, a magnificent castle awaits. It combines stunning interiors with a rich heritage of science and nature. Open year-round, the Historic Science Centre invites you to explore its fascinating galleries, featuring wonders like the Great Telescope, the Lunar Heat Machine, one of the world's oldest darkrooms, and a steam turbine in the engineering room.  

Since 1620, the castle has been the ancestral home of the same family, and from May to September, you can join guided tours to uncover its captivating history. Wander scenic trails, attend special events, and finish your visit with a treat at The Courtyard Café.
