How old is Newgrange?
Newgrange is a round mound some eighty-five metres across, ringed by ninety-seven great kerbstones, several of them carved with spirals and lozenges. A stone-lined passage nineteen metres long leads to a chamber with three recesses, roofed with overlapping slabs that have kept it dry for five thousand years. Burnt and unburnt human bone was found in the recesses.
Above the doorway is an opening the excavators called the roof-box. For a few mornings around the winter solstice the rising Sun sends a beam through it and along the passage floor, lighting the chamber for about seventeen minutes.

What sets Newgrange apart
The roof-box is what makes Newgrange singular. It is a slot built over the doorway, with a stone that could be slid aside, so that light could reach the chamber even when the door was blocked. The passage rises as it goes in, and the floor of the chamber lies level with the box, which is why only a low Sun can send its beam the whole length. The builders had to plan this before the mound was raised over it.
- Built: about 3200 BCE
- Mound: some 85 metres across and 13 metres high
- Passage: 19 metres long
- Midwinter light: about 17 minutes at sunrise, on the days around 21 December
- Excavated: 1962 to 1975 by Michael O'Kelly, who first recorded the beam in 1967
Often mistaken for something else: Stonehenge is an open ring aligned on the solstices for those standing in it; Newgrange is a closed tomb into which the midwinter Sun is let for a few minutes.
The story behind Newgrange
The tomb was built by farming people about 3200 BCE, some centuries before the great stones of Stonehenge and before the pyramids of Egypt. Its entrance was rediscovered in 1699. Michael O'Kelly excavated and restored it from 1962 to 1975, and in December 1967 he stood in the chamber and saw the beam arrive, as local tradition had said it did. Irish legend made the mound the house of the god called the Dagda and his son Aengus. The white quartz wall of the front is O'Kelly's reconstruction, and not all archaeologists accept it.
Why Newgrange matters
Newgrange is the oldest building known that was plainly designed to catch the Sun on one day of the year, and it still works.
How to read Newgrange
Guides at the Boyne valley sites show the beam with a lamp on ordinary days, since the chamber is too small for crowds at midwinter.
Newgrange in practice: an example
Each year a lottery chooses a few dozen people to stand in the chamber at dawn on the days around 21 December.
Where readings of Newgrange go wrong
Entry is by guided tour from the visitor centre only, and the passage is low and narrow, which some people find hard to bear.

Common questions
How old is Newgrange?
About 5,200 years. It was built around 3200 BCE, which makes it older than the great stone ring at Stonehenge and older than the pyramids at Giza.
What happens at Newgrange on the winter solstice?
At sunrise on the mornings around 21 December a beam of sunlight enters through an opening above the door, runs up the passage and lights the inner chamber for about seventeen minutes.
Was Newgrange a tomb or a temple?
Human remains were found in it, so it was a burial place. Its size, its carvings and its midwinter light suggest it was also a place of ceremony for the living.
