On a visit to family in Ireland, we were taken to a wonderful place and stepped back 5000 years. Newgrange is one of 3 neolithic passage tombs in the Boyne Valley which were built before the pyramids of Gizza and before Stonehenge. The visitor centre is very well equipped and wonderfully descriptive with brilliant models, video presentations and replicas of stone age life.
The centre has excellent catering facilities, which was very useful as you are given a time slot to go in a shuttle bus to the tomb itself.
Visitors are taken, by tour guide, into the tomb and given a demonstration of dawn at Winter Solstice when the rising sun lights up the centre of the chamber via the East facing passage. A magical experience.
Must see, never forget experience.
