The Court Cairn in Clerhanmore In Clerhanmore there is the remains of an ancient burial site, a court cairn. It was used as a tomb by Stone Age people to bury their dead. It was built between 3000 BC and 1800 BC and is the earliest evidence of people living in our area. This is a photo of the remains of a court cairn in Sligo. The one in Ballinaglera has only a few stones left. A court cairn was a tomb that had a long passage with people buried in little rooms off the passage. The entrance is a small courtyard where archaeologists believe Stone Age people may have held ceremonies before burying their dead. The plan of a court cairn Only some of the stones from the cairn in Clerhanmore are left but these are enough to show the original outline of the tomb.
