Discover more about Rock of Dunamase

Perched atop a dramatic limestone outcrop, the Rock of Dunamase stands as a silent sentinel over the Laois landscape. This historic site, dating back to early Christian times, has witnessed centuries of Irish history, from Viking invasions to Anglo-Norman conquests. Originally an early Christian settlement known as Dún Masc, the site was raided by Vikings in 842 AD. Its strategic location made it a valuable prize, and following the Norman invasion of Ireland in the 12th century, it became one of the most important Anglo-Norman strongholds in Laois. The castle was part of the dowry of Aoife, daughter of Diarmuid Mac Murrough, King of Leinster, upon her marriage to the Norman conqueror Strongbow in 1170. Later, it was part of another wedding gift when their daughter Isabel married William Marshal, Earl of Pembroke. The Rock of Dunamase changed hands several times, eventually falling into the possession of the O'Moore family. The castle's story took a violent turn during the Cromwellian invasion in 1650 when it was largely destroyed. Today, visitors can explore the atmospheric ruins, including remnants of the Great Hall and the tower gate, and imagine the lives of those who once occupied this imposing fortress. The site offers stunning views of the surrounding countryside, making it a rewarding destination for history buffs and sightseers alike. Evidence of a lime kiln near the gatehouse indicates that stones from the walls were used by local farmers to create lime for their fields.
