"There's been a pub here since the 1800s," he smiles. "I've spent my life behind this bar.
Located in the village of Murrisk, just outside of Westport on Ireland's west coast, the pub stands at the foot of Croagh Patrick, the holiest peak in Ireland. About 100,00 people hike the trail to the summit each year in honour of St Patrick, Ireland's patron saint. Most stop at Campbell's on the way back down for a pint and a glimpse of life as it used to be.
But amongst all the craic this year, the truth about the man behind the myth would have many St Patrick's Day revellers spluttering into their pints: Patrick was probably a Welshman.
This Friday on the Duncan Barkes programme on City Talk FM, we will be talking about ways to celebrate St Patrick's Day, climbing Croagh Patrick and just who was the man now synonymous with Ireland's biggest annual booze up.
Listen in from 10.15am this Friday. Send me your comments and I'll get them on air.
