Entrance Stone of Passage Tomb at Newgrange, Co. Meath. Ireland.
At over 5,000 years old it is the older cousin of Stonehenge and it predates the pyramids by about 500 years. Little else survives from this period. The tomb itself is massive, roughly circular in shape & covers an area of approx. one acre. Inside, a long passageway leads to a central burial chamber. Only 24 - 26 people at a time can go into the tomb.
Archaeologists remain unable to uncover the significance the site held for the people who created it or the mysterious spiral, diamond and circular patterns carved into some of the stones that surround the tomb & sit at the passage entrance.
