“If you ever find yourself in Dingle” sounds like the start of a joke. I don’t know what the rest of it would be, but if you do ever find yourself there, there’s a beautiful walk out from the town’s harbor, past this tower, and then to the cliffs beyond.
The date given for the tower, called Hussey’s Folly, is 1845. That was the first of Ireland’s devastating famine years. The construction was a make-work project, something devised by a local landholder for the poor and hungry to do in return for wages or food. Similar projects, often involving exhausting physical labor like road-building, were carried out all over Ireland as the country starved. Here’s a decent writeup on the “famine roads,” some of which are still used as part of the national road network: www.frrandp.com/2025/01/famine-roads.html.
