Sean's Bar
In Athlone's buzzing Left Bank sector, Sean's Bar styles itself as the world's oldest pub (a claim some cynics dispute, although a framed certificate from Guinness World Records says otherwise), dating to AD 900. This date has inspired the house beer, AD 900, a pale lager brewed in County Carlow. In 2018, Sean's produced two new whiskeys specially blended for the bar: one is dedicated to Luain, the first innkeeper, and is a blend of grain and malt, while the other is a malt whiskey called Clonmacnoise, a tribute to the monks who perfected the art of distillation, and with which you can wash down a complimentary dark chocolate whiskey-infused truffle. Sawdust on the floor of this dimly lighted, low-ceiling, long, narrow bar helps give it a rustic look and soaks up spills. Framed pictures and prints line the walls alongside maps of the Shannon navigation system, and the beer garden stretches almost down to the water. There's traditional music—or on Wednesday, jazz and folk—most nights of the year.
Note the slight tilting of the floor; this was an early medieval feat of engineering---when the Shannon River's water rose and spilled into town, it would flow in one door and out the other.
