A brief history of County Laois

The first people in Laois were hunters and gatherers who passed through the county about 8,500 years ago. They hunted in the forests that covered Laois and fished in its rivers, gathering nuts and berries to supplement their diets.

Next came Ireland’s first farmers. These people of the Neolithic period (4000 to 2500 BC) cleared forests and planted crops. Their burial mounds remain in Clonaslee and Cuffsborough.

Around 2500 BC, the people living in Laois produced weapons, tools and golden objects. Visitors to the county can see a stone circle these Bronze Age people left behind at Monamonry, as well as the remains of their hill forts at Clopook and Monelly. Skirk, near Borris-in-Ossory, has a Bronze Age standing stone and ring fort.

The next stage is known as the pre-Christian Celtic Iron Age. For the first time iron appeared in Ireland, as factions fought bloody battles for control of the land. At Ballydavis, archaeologists have discovered ring barrows that date from this time period.

By the first century AD, Laois was part of the Kingdom of Ossory. The county was divided roughly into seven parts, which were ruled by the Seven Septs of Laois: O’More (O’Moore), O’Lalor, O’Doran, O’Dowling, O’Devoy (O’Deevy), O’Kelly and McEvoy.

When Christianity came to Ireland, holy men and women founded religious communities in Laois. Between 550 and 600, St. Canice founded Aghaboe Abbey and St. Mochua founded a religious community at Timahoe. An early Christian community lived at Dun Masc or Masc’s fort, on the Rock of Dunamase.

Electric Picnic Festival

Since 2004, thousands gather at Stradbally Hall. It began as a one-day festival and has now grown to a weekend-long festival of music, arts, comedy, and the community.

Take a look at Electric Picnic below:

Rock of Dunamaise

Mapped by Ptolemy in 140 A.D., plundered by Vikings in 842 A.D., the dowry of a princess in 1169, seat of the O’Mores of Laois in the 14th century and destroyed by Cromwell’s forces in 1650 and currently the subject of a conservation project, this magical fortress is truly the stuff of legend and is well worth a visit.
