Rosskerrig Tower is the ruin of an early modern tower house overlooking Dunmanus Bay, precisely between Ahakista and Kilcrohane. The square, leaning tower stands on a small rise next to the R591 and forms a striking silhouette in the open landscape. Once this was a defensive residential tower of a local family, strategically placed to keep an eye on the bay and the passage over the Sheep’s Head Peninsula.

The country house itself is half hidden among old trees, making it primarily an atmospheric scenic waypoint on the transition between Long Strand, Kilkeran Lake and the ridge towards Galley Head.
