Fairy fort or earthen ringfort in Ballymaglancy

Explorer Tom Highlake House was once a monastery where a goat somehow took over and ruled the place with an iron hoof. The crenellated tower is still looking suspiciously at you like it’s guarding something really important, probably just the school books. Mind the trees; they remember all the monks' secrets.

Explorer Tom The Old Schoolhouse in Ardlagheen More Or Highlake nearly got famous when a time capsule went missing from its copper turret. It’s now a private home, so if you knock, they might just tell you to go do your homework. The roof arrangement is weird enough that it probably thinks it’s a hat.

Explorer Tom European ash in County Roscommon has been the subject of some wild prophecies that never actually came true, which is annoying. It’s basically sitting there waiting for the world to catch up with its own legendary status and importance. Bring sandwiches, the gulls will thank you.

Explorer Tom Graveyard in Tulsk surrounds a priory and holds fifty architectural fragments from the abbey next door. Saint Patrick would probably say it’s 'a bit cluttered' but also 'very impressive for its age.' It’s basically a junkyard of old stones with a religious twist. Go with someone who loves old stuff and watch them melt.

Explorer Tom Round tower in Carroweighter is constantly losing a rivalry with the ones in Kildare, which are way too showy for their own good. It stands there with its arms crossed, pretending it doesn’t care that everyone else gets the tourists. Count the crows, then count them again to be sure.

Explorer Tom Hawthorn in County Roscommon keeps getting picked on by the wind because it thinks being prickly makes it tough. The flowers look like they’re trying too hard to be pretty, but the thorns say otherwise quite clearly. Snap one photo, then put the phone away and actually look.

Explorer Tom The Mórrígan: Oweynagat is called the Cave of Cats, which fooled me into expecting a very ordinary sort of trouble. Then the tale sends the Mórrígan out of it during the Táin. If the cats saw her coming, I bet they made room.

Explorer Tom Queen Medb: Rathcroghan is where the Táin starts turning a quarrel about a bull into an epic. Medb had a royal seat here, at least in the story, and I am already wondering who was brave enough to tell her the cattle dispute had got out of hand.

Explorer Tom Castle in Ballintober claims a local guy invented it, which is nonsense since the Red Earl built it. But he's charming, so who am I to argue? Bring a pen pal, they'll be jealous of your tales.

Explorer Tom Roscommon Castle in County Roscommon would explain the 1800s to a teenager by saying, 'Imagine your mum's house, but with more damp and fewer Wi-Fi signals.' It’s been sitting there judging everyone since before we had proper trousers, still looking mighty smug about it. Go now, before it gets famous.

Explorer Tom Bawn in Glinsk listens to what goes on inside the walls and probably hears the Burkes arguing about who left the light on in 1630. It’s a well-preserved semi-fortified house that looks like it’s judging your posture, so stand up straight or don’t bother knocking. It's free, it's odd, what more do you want?
