On the pictures, you can see Newgrange: an ancient prehistoric monument (it was rebuilt to show tourists). It is as old as monuments in the south of England (in Stonehenge) and monuments in Brittany, France. At the prehistoric period, people came to the British Isles and built vast monuments. What were they used for? Archeologists are sure they were for the prehistoric people's religion: the monuments were probably linked with the sun and the moon.
