It's nearly time for the amazing phenomenon of the solstice at Newgrange, Co. Meath. When the tomb was constructed over 5,000 years ago it was built in such a way that sunlight could enter the chamber through a roofbox at dawn on the shortest days of the year.

If you are lucky you can witness this incredible event next Winter by taking part in the annual Newgrange lottery or you can view the event live by Webcast from about 8:30am on the 21st of December.
