quoting from article:

"For the first time ever, people all over the world can watch sunlight creep into Newgrange passage tomb on winter solstice.

Weather-permitting, of course.

A live stream organised by the OPW and Fáílte Ireland is set to broadcast the moment when the 5,000-year-old tomb's internal chamber is lit up.

Newgrange is believed to be older than Stonehenge and the Egyptian pyramids, and its "alignment" is considered a marvel of Neolithic engineering.

50 years ago, on December 21, 1967, Irish archaeologist Dr. Michael J. O’Kelly stood inside the famous passage tomb as the light from the rising sun travelled 19m up the corridor to illuminate the central chamber. 

Dr O'Kelly is believed to have been the first human to witness the winter solstice from inside Newgrange in millennia.
