Considered to be the oldest and most famous prehistoric site in all of Ireland, Newgrange is a tomb that was built from earth, wood, clay, and stone around 3100 BC, some 1000 years before the construction of the pyramids in Egypt. It consists of a long passage that leads to a cross-shaped chamber that was apparently used as a tomb, as it contains stone basins filled with cremated remains.
The most unique feature of Newgrange is its careful and sturdy design, which has helped the structure remain completely waterproof to this day. Most amazing of all, the entrance to the tomb was positioned relative to the sun in such a way that on the winter solstice, the shortest day of the year, the rays from the sun are channeled through the opening and down the nearly 60 foot passageway, where they illuminate the floor of the monument’s central room. Archeologists know Newgrange was used as a tomb, but why and for who still remains a mystery. The painstaking design needed to guarantee that the yearly solstice event occurs suggests that the site was held in high regard, but other than the obvious hypothesis that the sun featured prominently in the mythology of the builders, scientists are at a loss to describe the true reason for Newgrange’s construction.
The Megalithic Passage Tomb at Newgrange was built about 3200 BC. The kidney shaped mound covers an area of over one acre and is surrounded by 97 kerbstones, some of which are richly decorated with megalithic art. The 19 metre long inner passage leads to a cruciform chamber with a corbelled roof. It is estimated that the construction of the Passage Tomb at Newgrange would have taken a work force of 300 at least 20 years.
