Fairy fort or earthen ringfort in Sheegeeragh

Explorer Tom Graveyard in Kilcooley is sitting on a low hill pretending it hasn't been expanded for centuries. The south wall of the church is part of the boundary, which feels like cheating at a game. Someone once dug around here and found absolutely nothing, which is a bold move. Stick around for the light changing, it's a show.

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 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 Post box in Ardlagheen More has a ghost that’s too lazy to haunt it, preferring to nap inside the metal shell instead. It sits by the old monastery, collecting letters that never quite got sent or delivered. Knock twice and see if you hear a snore from within.

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 Rathcroghan claims a fake royal visit happened here that nobody can disprove because everyone forgot the date. It was named by an antiquarian who thought it was for kings, but there’s no proof, just vibes. Ten minutes here and you'll have a yarn for the pub.

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 Common Lime in County Roscommon is so pretty that Vikings probably wandered straight into its branches trying to find their way home. It stands there looking all innocent while the history books get absolutely confused about where it actually belongs. Stick around for the light changing, it's a show.

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?
