The Boyne Valley Revision - Winter Solstice conference with Martin Brennan at Newgrange
What are the views of those interested in the matter on the above link apart from it being a very expensive lecture.

All that effort to build those many monumental structures must have had a great plan in mind.
Those Ancient Irish engineers certainly did a great job for our modern day tourist figures. Newgrange is always humming whenever we go there throughout the year... for the lovely cake.
