Newgrange Clock Marks Mid-winter

An ancient Irish "solar clock" have been beamed to a global audience from a tomb in Ireland.

For five days around the 21 December winter solstice - the shortest day of the year - the sun shines deep into a tomb in County Meath, flooding the chamber with light.

The Newgrange tomb, now one of Ireland's top tourist attractions, dates to about 3200 BC - 1,000 years before Britain's Stonehenge was built and 500 years before Egypt's Great Pyramid of Giza.

Now, for the first time, the phenomenon was streamed live on the internet.

Speaking before the event, Claire Tuffy, Manager of Newgrange, said she was delighted it would be a clear sunrise, because without a midwinter sun the solstice "clock" would not work.

"It is quite a leap of faith for some international visitors to travel thousands of miles to get here on the off-chance of clear skies. It is a big commitment time-wise and financially," she said.

"But people don't really care about the weather. It is the anticipation that is the most exciting part of the event."

This year, a record 28,106 people from around the world applied to be one of the 50 lucky people allowed into Newgrange's cramped chamber, on one of the five days surrounding the solstice.

The prehistoric tomb was carefully aligned by its Neolithic builders so the sun only cuts through the gloom of the chamber at sunrise through a small window above the entrance.

When skies are clear, the rising sun slowly shines all the way down the 19-metre long chamber into the centre of the tomb, lighting it for up to 17 minutes before the rays disappear and darkness returns.
