Trapping the winter solstice at Newgrange might not be the 5,000 year old phenomenon we thought it was. 50 years might be more accurate, according to new research

The winter solstice light show at Newgrange in Co Meath is not the 5,000-year-old wonder we thought it was, according to a former State archaeologist. Instead says Michael Gibbons, 50 years might be more accurate. 

In an article published in the archaeological journal Emania, Gibbons and his nephew Myles query the reconstruction work done on the ancient tomb in the 1960s and say that the famous roofbox which makes possible the trapping of the sunlight may only date from then.
