Ireland: Athlone and Sean's Bar - The World's Oldest! - Roaming Together

Posted on May 16, 2026May 30, 2026 by jim

Athlone sits almost exactly in the geographic center of Ireland, if you drew a big X across the country and marked the middle, you’d land here.
It only ended up on our radar as a potential halfway point between Galway and Dublin, and then we stumbled across Seans’s Bar in our research.
First – The River Shannon has always been Athlone’s single reason for even existing.
Whoever controlled the crossing controlled the midlands, which is why Athlone Castle went up on the west bank back in the 12th century and why the town has been fought over more times than anyone cares to count.
The castle is still there, which is more than you can say for most things built in the 1100s.
So is the Cathedral of Saints Peter and Paul (the cathedral names here kill me) is the visual highlight of the skyline, and the river is the anchoring centerpiece.
The town itself really has very little to attract the tourist.
Except.
Guinness is, of course, everywhere – painted on walls, hung in windows, advertised on anything that will hold still long enough.
If you’ve been following along on this Ireland trip, you already know this is simply the ambient condition of the country.
The reason most people actually make the stop in Athlone, though, is Sean’s Bar.
And yes – we went – it’s not optional to stop here and skip it.
Sean’s Bar claims to be the oldest pub in Ireland, possibly the oldest in the world, with verified origins going back to around 900 AD.
The Guinness World Records people have apparently weighed in and agreed.
The walls are thick, the ceilings are low, the place looks exactly as old as it is, and the pint tastes the same as it does everywhere else in Ireland – which is to say, very good.
It was packed with visitors when we arrived, because it is always packed with visitors – but that’s the deal when you’re the oldest bar in the world.
You don’t get that title and then complain about the crowd.
Fun fact about the Guinness Book of World Records – it’s THAT Guinness. It was created in 1951 by Sir Hugh Beaver, the managing director of Guinness Breweries as a method to settle debates in pubs. The Wikipedia article is worth a read.
Athlone isn’t going to be the highlight of your Ireland itinerary.
It’s not the Cliffs of Moher, it’s not Kilkenny, it’s not the Ring of Kerry.
But it has the oldest pub on earth, and if it’s on your route it’s worth the stop.
