Geologic Formation Nature / Park

Storm the castle at Rock of Dunamase, a fortress dating back to the 12th century and once pillaged by Vikings. The rock itself stands above a flat plain, which holds the castle ruins and offers picturesque views of the countryside. The structure has passed through many hands, including the Normans and local Irish lords, and local tradition says it was besieged and blown up by the Cromwellian generals in 1651. While there are no records of these events, it is probably the best explanation for the ruins you can explore today. Take care when navigating the castle, as some parts can be dangerous.

Great for young children. Short walk from carpark. Thankfully undeveloped. Nothingcommercial. Great views across Co Laois for such a low hill.

Amazing and under appreciated We were just about the only people there, crazy as it's fantastic. Great history and great to walk amongst the ruins, like a movie scene

Google the history of this castle. Off the tourist path- remarkable story tracing back to the last time Ireland was independent. Great picture spots.
