Archaeologists from Ireland and Slovakia have begun a project to investigate whether there are any further hidden or undetected passageways and chambers at Newgrange in the Brú na Bóinne World Heritage Site in Co Meath.

The team are deploying a technique (microgravity survey) which has been used successfully to identify the locations of passages and chambers at the pyramids in Egypt.

This is the first time the equipment has been used in Ireland.

Newgrange, which was constructed more than 5,000 years ago, is best known for the illumination of its passage and chamber by the winter solstice sun.
