Newgrange is a famous megalitic tumulus, which was build about 3000 b.C. in
a time when most of Ireland was covered by large forests. It is about 500 years
older than the Egyptian pyramids and 1000 years older than Stonehenge.
The chamber in the center of the tumulus is illuminated by the rising sun
at winter solestic. About four generations worked at that monument with such
a sophisitcated technique that no water entered the chamber since 5000 years.
The stone at the entrence is engraved with circular symbols.
When the chamber was entered the first time again in 1699 only the remains of
three people were found.
