Dunluce Castle: One of Northern Ireland's most famous castles
Dramatically perched on a clifftop overlooking the Atlantic Ocean, Dunluce Castle is one of the most recognisable landmarks in Northern Ireland. The striking medieval ruin is connected to the mainland by a narrow bridge and has captivated visitors for centuries with its spectacular setting and fascinating history. Once the seat of the MacDonnell clan, the castle has become one of Northern Ireland's most photographed attractions and remains a must-see stop for visitors exploring the Causeway Coastal Route.
Visitors can explore the findings of archaeological digs within the cobbled streets and stone merchants’ houses of the long-abandoned Dunluce Town, while the dramatic history of Dunluce is matched by tales of a banshee and how the castle kitchens fell into the sea one stormy night in 1639.
Hillsborough Castle, Castle Ward and Historic Sites in County Down
(Access is only available to the gardens and café at Hillsborough Castle and Gardens during the winter. The Castle reopens in the spring).
Originally completed in the 1790s, the magnificent Hillsborough Castle is the official residence of the Royal Family when they visit Northern Ireland. Take a tour through the elegant staterooms and into the majestic throne room and drawing room while finding out every inch of its fascinating history with your well-informed guide.
Not too far from Royal Hillsborough, castle chasers will find Brownlow House. Known locally as ‘Lurgan Castle’, it was built in 1833 and really has a tremendously quirky character. Its array of intricate chimney pots, each a different design, are surmounted by a beautiful lantern-shaped tower and the whole site commands superb parkland and lake views. There are some great stories of American and British troops stationed here during World War 2 and you can discover more about them over a tasty cup of tea and delicious scone in the excellent tearoom.
Set within the grounds of the impressive 820 acre demesne there are more than 30 kilometres of walks and trails within Castle Ward in County Down. The Castle Trail takes you to Audley’s Castle, which fans of Game of Thrones® will recognise as Robb’s Camp. This is a great spot in County Down to get away from it all and dig into a bit of history at the same time.
County Down is also home to two of the best-preserved abbeys in Northern Ireland. At the south east edge of Newtownards the substantial remains of Grey Abbey date from 1244. It went through quite a history before falling into disuse in the 18th century. Today, you’ll find the remains in the beautiful parkland setting of the nearby Rosemount House.
A little further south, John DeCourcy, of Carrickfergus Castle fame, also built Inch Abbey. According to the history texts he was compelled to do so for his part in the destruction of another abbey. Paying his dues you might call it.
Ancient Monastic Sites, Abbeys and Heritage Attractions
Up the road on the western bank of Lough Neagh sits one of Ireland’s oldest High Crosses. Standing six metres high, the Ardboe Old Cross dates from the tenth century. The twenty-two panels depict stories and scenes from the Old Testament and New Testament and are stunningly beautiful in their simplicity.
Carrickfergus Castle and Causeway Coast Historic Sites
Standing proudly on the shores of Belfast Lough since 1177, Carrickfergus Castle is one of the best-preserved Norman castles in Ireland and among Northern Ireland's most iconic historic landmarks. For more than 800 years, its imposing walls and towers have withstood sieges, invasions and centuries of change, making it an essential stop for anyone interested in medieval history. Visitors can explore the castle on a guided or self-guided tour and discover the stories of the soldiers, nobles and kings who once passed through its gates.
Continuing north, the picturesque Glenarm Castle sits at the gateway to the Glens of Antrim. Home to the McDonnell family, Earls of Antrim, for more than 400 years, the estate combines rich history with beautiful walled gardens and one of the most scenic settings on the north coast.
As you travel along the Causeway Coastal Route, you are sure to come across the magnificent Dunluce Castle. This is one of Northern Ireland’s most famous and most photographed landmarks. The medieval ruin stands on the edge of a cliff and can be approached only by a bridge. Dating from 1500, it has a fascinating history. Would you believe that at one point it was owned by Winston Churchill and it is said that this place was highly influential in stories of C.S. Lewis. Well worth a trip.
From here, walkers will enjoy the wonderful cliff walk to Dunseverick Castle near the village of the same name. This place dates back to the time of Saint Patrick so it is of little surprise that only ruins remain. This one is more about the journey than the destination.
Benburb Castle and Historic Attractions in County Tyrone
In County Tyrone you can stretch your legs and take in some turrets at Benburb Castle, a plantation bawn built in 1611. Today, there are a number of trails to explore in the Benburb Valley Park where the River Blackwater has carved out a beautiful gorge through the countryside.
Enniskillen Castle, Devenish Island and Historic Sites in Fermanagh
Perched dominantly on the banks of Lough Erne, Enniskillen Castle in County Fermanagh, harks back to the might of the ruling Gaelic Maguires. They were the first occupants of this imposing structure almost 600 years ago and their story is an important part of the history of the whole island of Ireland. You can find out more about that story in the castle’s Inniskillings Museum.
Hidden away in the stunning Fermanagh Lakelands, you’ll come across the island of Devenish. This is home to the ruins of a parish church, St Mary’s Augustine Priory and an impressive round tower.
The island has been raided by Vikings and devastated by fires before re-flourishing in the Middle Ages as a centre of learning and literature. This spot is well looked after and gives a great insight into the monastic sites dotted around the island.
Navan Fort: Ancient History and Mythology in Armagh
If you’re passing through Armagh be sure to climb to the top of the ancient “Emain Macha” or Navan Fort. In early Irish history and legend this spot was the earliest provincial capital of Ulster. Today it is a large earthwork on top of a drumlin but as you look around you, you can imagine it as the site of ancient pagan ritual and ceremony.
With castles and heritage sites like these for starters, who knows where your journey into the past will take you in Northern Ireland?
