The Rock of Dunamase is an impressive Celtic fortification that overlooks the valley of the O'Moores. Originally it was the site of a early Christian settlement which was pillaged by the Vikings in 842.

The fort has spectacular views of the surrounding countryside and makes a great spot to stop for a refuel.

The towering Rock of Dunamase is such an obvious strategic place to build a fortress. Through the centuries, warriors have fought to control this craggy outcrop and it simply reeks of violent history. There are stunning views of the surrounding countryside to be had from here too and it's a great place for a rest stop.
