Ruins of Clare Castle

The earthworks and crumbling stone foundations that make up Clare Castle sit on a low rise just outside Markethill, commanding what would have been strategic views across the surrounding countryside. What you're looking at is essentially a Norman motte-and-bailey stronghold that's been gradually reclaimed by grass and time - there's no grand keep standing proud, just the outline of where one once was.

It's the sort of place that appeals more to archaeology enthusiasts and history walkers than families expecting a visitor centre and gift shop. The site itself is free and accessible, though there's little interpretation on the ground, so you'll want to do your homework beforehand or bring someone who knows their Norman fortifications. Allow twenty minutes to properly explore the earthworks and get your bearings from the top - the walk up is straightforward enough.

The real value here is context. If you're staying at Tepee Valley Campsite nearby and want to get a feel for the medieval landscape of this part of Armagh, it's worth the short detour. The ruins tell you something about how power was held and defended in the 12th century, and you won't be fighting crowds to see them. Go when the ground isn't sodden - winter visits can turn the site into a boggy trudge - and pair it with other attractions in Markethill if you're making a proper morning of it. Solo walkers and local history buffs will find it more rewarding than casual tourists.
