Newgrange Winter Solstice

Newgrange winter solstice

Newgrange winter solstice is one of the great prehistoric alignments in the Boyne Valley. The mound sits on a ridge over the River Boyne, in Ireland’s Ancient East. On the shortest days of the year, sunrise can light the passage and chamber. That happens on several mornings around 21 December, not only on the exact date.

People gather in the dark before dawn. The mound stands out against the early sky. Then the first light shows the quartz wall and the carved kerbstones. The river below is often still in shadow. Cold air and bird calls carry across the ridge. For many visitors, that wait is part of the event.

Neolithic builders aligned the tomb to catch the sun on mornings around the solstice. A small opening over the entrance, the roof-box, lets a narrow shaft of light run the passage. As the sun rises, the beam reaches the inner room. The dark chamber then takes on a warm gold glow. Outside, the same sunrise washes the kerb and the white wall.

On a standard OPW tour, visitors do enter the passage and chamber. A light show inside also explains the midwinter sun. However, the live event is different. At the real solstice, only lottery winners go inside. Other people stay at the entrance and watch the sky. Cloud to the southeast can stop the beam. Even so, crowds still come for the longest night to end.

Once the beam is in, it does not stay a thin line. As the sun climbs, it widens across the chamber floor. Then it fills more of the room before it fades.

The event lasts about 17 minutes from around 9 a.m. The builders raised Newgrange more than 5,000 years ago. So it is older than the pyramids at Giza and older than Stonehenge. They likely marked the turn of the year. It may also have stood for life’s return after the longest night.

Each year, people still wait outside at dawn. Places inside the chamber go out by a solstice lottery. Cloud on the eastern horizon can stop the beam. Even so, waiting out the longest night is a powerful experience.

The 1967 sunrise inside the chamber

Professor Michael J. O’Kelly first recorded the beam in modern times. He excavated Newgrange from 1962 to 1975. Early on, local visitors told him a tradition. They said the rising sun would light the triple spiral in the end recess. However, he could not find anyone who had seen it. At first, he thought people might be mixing it up with Stonehenge and midsummer.

Then he considered a southeast alignment at midwinter. He left Christmas preparations to his wife, Claire. He traveled from Cork to Newgrange the day before the solstice to test the idea.

Several minutes before sunrise on 21 December 1967, O’Kelly stood alone in the dark chamber. The room then began to brighten. A beam of sunlight ran the passage. He later wrote that it lit “everything as it came until the whole chamber, side recesses, floor and roof twenty feet above the floor, were all clearly illuminated.”

He stood still for a while. In his mind, he even feared that the Dagda might bring the roof down. The roof stayed up. Then the sun retreated. He walked out. He was the first person in modern times to see sunlight reach the chamber.

Dr. Jon Patrick later showed that the alignment was deliberate. He reported: “It therefore seems that the sun has shone into the chamber ever since the day of its construction and will probably continue to do so forever.” O’Kelly then found that the event runs for several days before and after the solstice. He came back at least once a year for the rest of his life.

Between the bright sky and the long glittering silver ribbon of the Boyne the land looks black and featureless. Great flocks of starlings are flying across the sky from their nighttime roosts to their daytime feeding places. The effect is very dramatic as the direct light of the sun brightens and casts a glow of light all over the chamber. I can even see parts of the roof and a reflected light shines right back into the back of the end chamber.
