Ring-ditch in Knocks

Explorer Tom Dunshaughlin Civic Offices in Dunshaughlin thinks it’s too cool to need heating or cooling, which is bold for an office building. It’s got a contemporary design that makes other buildings feel outdated and a bit jealous. Go at sunset and thank me later.

Explorer Tom Dunshaughlin National School in Dunshaughlin is built on top of a legend about a giant who lost his keys. The 1887 date on the plaque is the only thing keeping it grounded. Stand where the owner would be if they were there to tell you off.

Explorer Tom Killeen Castle has a curse that only affects people who don't wave when they pass by, so make sure you give it a big thumbs-up from the car window. It’s a tower house sitting on a slight slope, looking like it’s about to tip over into the next county if the wind picks up. The Cussack family probably didn't know what they had until it started growing moss. Find the wonkiest bit and send it

Explorer Tom Dunsany Cross is like the awkward uncle at a wedding, standing right by the castle entrance and pretending it doesn’t know anyone. It’s made of granite but people used to think it was limestone, which is a classic case of mistaken identity for a two-meter stone. It’s just there on the road, looking rectangular and unimpressed by your outfit. Have a look and decide if I was lying.

Explorer Tom Rath Meave is a henge that sits on an escarpment near Tara, looking down its nose at everyone who thinks they know what a henge is. It’s got two banks that have never quite agreed on which side to lean, creating a lovely architectural argument. Imagine its opinion of the road leading to it; probably that it’s too busy for casual traffic. Bring a pen pal, they'll be jealous.

Explorer Tom Battle of Tara Hill is still trying to remember if it was a fight or just a very aggressive family gathering. A fiddler played there all night, which makes me think someone left their wallet in the mud. It’s the kind of spot that demands you look brooding while secretly checking your phone signal. Ideal for a moody photo you'll pretend wasn't posed.

Explorer Tom Battle of Tara (Ireland) in County Meath has had more names than I have socks in my drawer right now. Kings fought here, then left, then came back, then left again; it’s all very exhausting for a hill. Have a nosey, politely.

Explorer Tom Lia Fáil: Hill of Tara is a stone with high standards. Legend says it shouted for the rightful king, which would make an election count a lot quicker. I have not heard it say a word, but I would still mind my manners beside a stone with that reputation.

Explorer Tom Come looking for a king's chair? Bring imagination, not a throne. The Hill of Tara is not one neat royal throne with a handy label. About twenty old monuments are visible here, and surveys and aerial photographs have found at least three times as many again. The Mound of the Hostages is older than the kings in the stories; its passage catches sunrise around Samhain and Imbolc. I would declare myself High King, but the hill would demand better references. Inside the great Enclosure of the Kings are earthworks that make a figure of eight, and the standing stone called the Lia Fáil is traditionally said to roar for the rightful ruler. I gave it a polite chance and heard the wind, which I will take as a firm refusal. The Rath of the Synods suffered damage when searchers hunted here for the Ark of the Covenant in the early twentieth century. Ancient ground can be harmed by very modern certainty. Walk the marked paths and leave every bank and stone where it is. Tara gives you plenty to imagine without moving a grain of it.

Explorer Tom Saint Patrick's in County Meath has strict rules for visitors, mostly about not tripping over your own feet. It’s a bit shy about being famous for that one statue. Get there early and have it all to yourself before the crowds arrive. The grass is suspiciously green, probably from all the attention.
