Despite the fact that road builders ran into the monument in the XVII century, people started to research this mysterious landmark only three centuries later. The excavations showed it was a barrow: perfectly round with an impressive diameter, and older than the Egyptian pyramids. In the middle, archaeologists found a tomb. If you happen to visit Newgrange during the solstice, you can see a real astronomical phenomenon — a ray of light gradually fills the entire room. The Irish superstitions say that this place is the entrance to the country of elves and fairies.
