Built 5000 years ago on a hillside in the Boyne Valley, long before the pyramids in Egypt, Newgrange is a place of wonder and mystery. Who were the people who made this underground passage and chamber? How did they do it without machines? Was it a burial place or a temple to the gods? Do the symbols carved into the stone have a special meaning? Why was Newgrange lost for centuries? And above all how did those people so long ago know how to create the lightbox and banish darkness on the shortest day of the year – the Winter Solstice?
