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 (clouds are forecast).
A live stream organised by the OPW and Fáílte Ireland will broadcast the moment when the 5,000-year-old tomb’s internal chamber is lit up (#Solstice2017).
You can watch it live (below) from 8.30am on Thursday, December 21.
The annual event, which sees sunlight enter the roofbox of the Co. Meath tomb and light up its inner chamber over the course of around 17 minutes, is simulated for all visitors to Newgrange – but only a lucky few get to see the real deal.
Each year, the OPW runs a Winter Solstice Lottery – in 2017, it says, over 33,000 people applied from as far afield as Austria, Italy and the US.
