Summary
New Grange is the earliest and most well-known passage tomb in all
of Ireland. It is located near Slane in County Meath at the bend
of the River Boyne. The actual dates of the tomb vary; uncalibrated
radiocarbon dates give a range near 2500 BC or 3200 BC calibrated.
This predates both Stonehenge and the Egyptian pyramids. New Grange
was occupied during the late Neolithic and the Beaker period, its settlers
having come from Britain. The polypod bowls found at the site give
evidence that the Middle Rhine Beaker people inhabited the site.
