A Norman keep on a rock
King John's Castle
Hugh de Lacy started building in the 1180s on a pinnacle of rock at the entrance to the lough. King John himself turned up in 1210 on his way north to fight Hugh's son, stayed three days, and lent the place his name forever. The western gate was designed so only one horse and rider could squeeze through at a time. The castle has been under restoration for years; the silhouette over the harbour is the postcard you came for.
An Táin Bó Cúailnge
The Brown Bull
The oldest story in the Irish language is set on these mountains. Queen Medb of Connacht came east to steal the great bull of Cooley, Donn Cúailnge. The seventeen-year-old Cú Chulainn held the entire army off at the river fords, single-handed, while Ulster slept under a curse. The Táin Way walking trail follows the geography of the cattle raid. You can stand on Slieve Foye and look down at the ground the bull was driven over.
PJ O'Hare's whistle
The leprechaun law
In 1989 PJ McCoy found a small skeleton, a bone whistle and four gold coins on Slieve Foye. He put them behind the bar of his pub on Tholsel Street. Twenty years later Kevin Woods — the 'Leprechaun Whisperer' — lobbied the EU and got Carlingford's leprechauns formally protected under the 2009 Habitats Directive. It is, on paper, the only place in the European Union where the leprechauns are a legally protected species. Make of that what you will. The bone whistle is still behind the bar.
A medieval town that survived
The walls and the gate
Carlingford was walled by the 14th century. The Tholsel — the last surviving medieval town gate in the town, and one of very few in Ireland — still spans Tholsel Street. It was gate, jail, and the room where the burgesses argued about taxes. The Mint on the same street was a fortified merchant's house granted licence to strike coins in 1467. Taaffe's Castle is a tower-house that became a bar. Five centuries of building stock, mostly intact, mostly still in use.
