Clough Castle

Perched on a rocky outcrop overlooking the Mournes, this medieval tower house sits quietly in the countryside between Newcastle and the coast. Dating from around 1570, Clough Castle is one of those proper Irish tower houses - four storeys of weathered stone that speaks to a time when every landowner needed proper defences. The structure remains largely intact, which is remarkable given its age and exposure to the elements.

History enthusiasts will appreciate the castle's connection to the Magennis clan, who controlled much of this corner of County Down for centuries. The views alone justify the visit - the Mourne Mountains rise dramatically to the west, while glimpses of the Irish Sea catch the eye to the east. It's atmospheric stuff, especially on those moody days when clouds roll across the peaks.

Walkers often include it as a stop on longer rambles through the area, though it's perfectly accessible by car. The site appears to be freely accessible, though there's no formal visitor centre or guided tours. Allow perhaps 30 minutes to explore and soak up the atmosphere - longer if you're keen on photographing the stonework or mountain backdrop.

Staying at one of the holiday parks near Newcastle puts you within easy striking distance. Tollymore Campsite is particularly well-placed if you're planning to combine castle-hunting with forest walks in Tollymore Forest Park.
