When it comes to rediscovering their ancient past, some countries are littered with monuments that show them the way. Egypt has its pyramids at Giza, and the ruins of the Acropolis display all the former glory of Athens. But for nations like Ireland, that distant history is a bit more difficult to uncover.

The foundations of their society are harder to spot, but are no less complicated. One burial ground has puzzled and enamored archaeologists for generations. But thanks to cutting-edge technology, experts are now picking up on key details that were previously hidden. But will some wish that this past remained a secret?

Not unlike Egypt, Ireland has its own Valley of the Kings, a wind-swept and rocky expanse where great chieftains were laid to rest thousands of years ago. Its most famous tomb almost blends in with the countryside.
