Cave in Glenbrack

Explorer Tom Ballynamantan House is an outbuilding that got left behind when its big house family moved away and never called back. The map makers got it wrong because they were drunk on pints at the local pub. Pop by and tell it it’s lovely anyway.

Explorer Tom Holm Oak in County Galway would write 'Seeking patient partner, no shedding required' on its dating profile because it keeps its leaves year-round. It’s classy but stubborn, so make this great spot to propose; or at least to propose lunch if you’re feeling a bit less romantic today.

Explorer Tom Roseville Cottage was nearly sold to a man who only wanted it for his horse. The thatch is holding on for dear life against the elements. Hang around long enough and the roof will probably fall off!

Explorer Tom Common Lime hosted a dance in 1974 that went so far everyone forgot how to get home until dawn. The branches still look like they’re mid-air, frozen in a move that nobody has been able to replicate since then. Bring your own legend, I’ve run out.

Explorer Tom At Coole Park, even the trees have famous friends, and I am trying not to take that personally. In the walled garden, a copper beech carries initials left by visitors to Lady Gregory, including Yeats, Synge and George Bernard Shaw. Yeats also found the swans here that inspired The Wild Swans at Coole. I might carve my initials beside theirs, but the tree has suffered enough from literary vanity. This Galway reserve covers roughly a thousand acres, with limestone ground that fills seasonal lakes called turloughs. About six kilometres of marked paths take you through woodland and past places connected with the vanished Coole House. Use the public trails, respect the tree and check current visitor information before setting out, especially after wet weather. Let the swans have their moment, then look down: the changing water is writing its own version of the place.

Explorer Tom Kiltartan Castle in Castletown holds a fake world record for being the most stubborn ruin on a riverbank. It’s been there since the de Burgo days, looking grumpy. It's free, it's odd, what more do you want? Just don't ask it to smile, it might cost you a coin.

Explorer Tom Newtown Castle in Castlequarter is round and proud of it, sitting in land that floods when it feels like it. It would use its lotto win to buy better boots for its owner. Tell the next person you meet it's haunted; it might be, or it might just be a damp echo.

Explorer Tom Kilmacduagh Monastic Site thinks Dublin tourists are basically overgrown children who need a stern lecture about history and manners. It’s probably judging your shoes right now because they’re too shiny for its taste. It's free, it's odd, what more do you want?

Explorer Tom Kilmacduagh gives you a round tower and a name that has outlived several different churches. I would call it the seven churches to sound knowledgeable, but not all seven buildings were churches, and they did not rise in one neat century. Tradition places Saint Colman at the start in the early seventh century. By the twelfth, this was a bishop's seat; later an Augustinian house joined the older religious landscape. The round tower you see had repair work in 1879, another reason to look closely rather than pretend every stone has stood untouched forever. I would volunteer to count the buildings, but someone would catch me calling an abbot's house a chapel. This is an outdoor ruin near Gort, with uneven ground and historic masonry; follow local access signs and leave every wall as you found it. Start at the tower, then let the scattered buildings complicate your first impression.

Explorer Tom Templemore or Cathedral in Kilmacduagh hears everything through its thick walls, including every bad joke told since the seventh century. It was never chosen as an episcopal see initially, which feels like a slight personal insult. Stand back, squint, and it looks like a castle.

Explorer Tom Graveyard in Kilmacduagh is probably complaining to the council about the lack of proper signage and the damp getting into its bones. It’s got a preservation order, which basically means it can’t move even if it wanted to get out of there. Bring a notebook and write the bit I made up.
