At 5,500 years of age Newgrange is 500 years older than the Great Pyramids of Egypt and even predates Stonehenge. One of the most famous prehistoric sites in all the world and it's only a little over an hour away from us.

Full of megalithic art, this structure was created long ago to pay respect to the rising sun on one very specific day of the year -- which also happens to be the shortest day of the year -- the winter Solstice in late December. For approximately seventeen minutes on this one day the sun shines through a carefully constructed passageway to illuminate the floor deep inside the chamber.

5,500 years! Can you imagine?

The sun's relationship with the earth hasn't really changed that much in all this time.

Has man really?
