The Rock of Dunamase is a popular historic attraction found overlooking the valley of the O’Moores, just outside Portlaoise, County Laoise. It was the location of an early Christian settlement known as Dun Masc and later became an important Anglo Norman fortification.

The Vikings pillaged the settlement in 842. Later, in the 12th Century, Dunamase became an important Anglo Norman fortification and was part of Aoife’s dowry when she married Strongbow in 1170.

Despite the castle’s ruined state, visitors can get a sense of its former grandiosity and also have the opportunity to take in stunning views of the surrounding countryside.
