The landmark Belfast Castle imposes itself on the city, with huge stone towers, grounds, woodland and views. It’s beautiful, but if you want blood and guts, go for Carrickfergus Castle, a favourite target for the Scots, Irish, English and even the French had a pop at it.
Jutting out over the Atlantic teeters the stunning Dunluce Castle, inspiration for GOT’s Castle Greyjoy. There are hundreds of years of non-fiction intrigue, plots and conquest etched into every battle-scared stone. And mind your step, the entire kitchen plunged screaming into the sea back in 1639.
