Explore Northern Ireland's Historic Castles

Northern Ireland has some of the finest castles on the island.  The earliest are from Norman times, but fortified homes continued to be built well into the 17th century, with more modern versions such as Hillsborough Castle and Belfast Castle being constructed in the 18th and 19th centuries. 

Here’s a selection of some our most impressive and intriguing castles.

Dunluce Castle, County Antrim

Dunluce Castle

Dating from the 14th to the 17th centuries, the iconic Dunluce Castle is strikingly perched on rocky cliffs overlooking the North Atlantic, and was the headquarters of the MacDonnell Clan.  Constantly fought over, it eventually succumbed to the power of nature, when part of it fell into the sea one stormy night in 1639.  It was abandoned shortly afterwards.  There is archaeological evidence of a village that surrounded the castle, which was destroyed by fire in 1641.  The castle and its magical setting are said to have inspired Cair Paravel in C.S. Lewis' Chronicles of Narnia

Tully Castle, County Fermanagh

Why not head off the beaten track and discover the beauty of Tully Castle, located on the shores of Lower Lough Erne between Enniskillen and Belleek.  This fortified house and bawn was built for Sir John Hume in 1619, who occupied the house until 1641 when it was attacked and burned.  The site includes a recreated 17th century style garden.  Nearby Monea Castle also dates to the Plantation of Ulster.

Carrickfergus Castle, County Antrim

Carrickfergus Castle

A striking monument from land, sea and air, Carrickfergus Castle represents over 800 years of military might, strategically located on the northern shore of Belfast Lough.  Originally built in 1177 by John de Courcy, this Norman castle has been altered throughout the centuries and has been in use as a garrisoned property until as late as 1928. The castle now houses historical and other displays as well as cannons from the 17th to 19th centuries.

Harry Avery O'Neill's Castle, County Tyrone

Harry Avery O'Neill's Castle

Picturesquely situated amid the foothills of the Sperrin Mountains near Newtownstewart, this castle is thought to have been built around 1320 by a local chieftain of the O’Neill clan.  This is unusual in that Irish chieftains of the time rarely built stone castles.  The main surviving features are the huge D-shaped twin towers and a large mound behind which formed the courtyard.  Nearby Newtownstewart Castle, dating to the early 17th century, is also worth visiting. 

Dundrum Castle, County Down

Dundrum Castle

Standing high above the town and bay of the same name, Dundrum Castle was a central fortification in the Anglo-Norman conquest of Ulster in the 12th century.  It features a tall circular keep at its centre, an inner and outer bailey and the ruins of the 17th century Blundell House.  Other castles in the once strategically important south Down area include Greencastle Royal Castle and Narrow Water Castle

Belfast Castle, Belfast

Belfast Castle

Located on the slopes of Cave Hill and offering stunning views over the city and Belfast Lough, Belfast Castle was built in the Scottish baronial style for the third Marquis of Donegall and completed in 1870.  Explore the landscaped gardens and Adventurous Playground, go for a brisk walk in the surrounding Cave Hill Country Park, then head indoors and enjoy a bite in the cosy Cellar Restaurant. 

Hillsborough Castle, County Down

Hillsborough Castle

This late Georgian mansion was built in the 1770s by the first Marquis of Downshire and remodelled in the 19th and early 20th centuries.  Today, it functions as the official residence of the Royal Family in Northern Ireland.  Take a guided house tour through the elegant State Rooms then explore the 98 acres of beautiful gardens (open until end of September).  While in this beautiful town, make sure to visit the picturesque Hillsborough Fort, originally built in 1650.
