The mounds prominent position at the top of a ridge overlooking the Boyne river and visible from miles around must indicate this place was an extremely important part of Neolithic life, religion, art and burial.

Many discoveries made during the excavations demonstrate that the builders not only were able to move vast quantities of heavy stone over long distances, they were also very adept engineers who planned and executed a pre-planned design that has stood for 6,000 years and still performs its primary functions. Grooves were carved into the roof stones to channel water seeping through the mound away from the passage and camber, the corbeled roof is still intact as it was the day it was finished and towers over five metres above the ground.
