Newgrange Winter Solstice 2025

Each December, visitors gather in the Boyne Valley to witness one of the world’s most remarkable prehistoric alignments. Newgrange, built around 3200 BC, is precisely aligned with the rising sun on the mornings around the winter solstice. For a seventeen minutes after sunrise, sunlight can enter through the roof box above the entrance and travel along the passage to illuminate the chamber floor.

The alignment itself works every year. What varies is the Irish winter weather, cloud sitting low on the eastern horizon at the wrong time can prevent the sunlight from entering the chamber.

In December 2025, public access to Newgrange ran for five mornings, from Friday 19th to Tuesday 23rd December. Chamber places were allocated by lottery, while members of the public gathered outside the mound each morning. Only one official live webcast took place, on the solstice morning Sunday December 21st.

How the Newgrange solstice works

Newgrange is not aligned with first light, but with the moment the sun rises high enough above the horizon to shine directly into the roof box. When conditions are right, a narrow beam of sunlight enters the passage and slowly advances towards the chamber floor, remaining visible in the chamber for 17 minutes.

Clear skies overhead are not enough. Cloud on the eastern horizon during a very short window around sunrise can block the sun even if the rest of the morning later turns bright.

The first morning of the solstice period began under clear pre dawn skies, with stars visible shortly before sunrise. The eastern horizon remained clear as dawn broke, allowing the sun to emerge at the critical time. Light entered through the roof box and progressed along the passage, illuminating the chamber and providing an excellent opening morning to the solstice period.

The second morning came close, but cloud crossed the eastern horizon at a critical time, preventing the sun from entering the roof box. The chamber remained unlit, although improving conditions later allowed sunlight to illuminate the passage.

The solstice morning itself was the only day with an official live webcast. A late break in the cloud at sunrise on 21 December 2025 allowed a brief sunbeam to enter the passage at Newgrange, prompting a cheer from those gathered outside.

For much of the critical window, the rising sun was hidden behind a bank of cloud sitting low on the eastern horizon, preventing sunlight from entering the roof box at Newgrange. As the minutes passed, it appeared increasingly unlikely that the chamber would be illuminated, and many assumed the opportunity had been lost. Then, almost at the last moment, the cloud thinned and briefly cleared. A cheer rose from those gathered outside the mound as the sun finally broke through, allowing a beam of light to enter the passage and travel steadily inward, reaching the chamber and marking a fleeting but memorable solstice moment.

Weather conditions deteriorated on the fourth morning with cloud cover and damp conditions at sunrise.

The final morning of the solstice period was overcast, though thankfully dry. Aside from those selected by lottery to be inside the chamber, there were around fifty people gathered outside, including tour guide Michael Fox. Once the lottery participants emerged, those waiting outside were brought into the chamber in three separate groups.

Although the sun did not enter the chamber that morning, being inside on a solstice day remains a rare and special privilege. Photographer and tour guide Anthony Murphy captured an image of Michael inside the chamber, echoing a photograph taken during the solstice in 2010 when conditions were perfect and the chamber was filled with a golden sunbeam.

Thousands celebrate ‘magical’ winter solstice sunrise at Newgrange ancient tomb

An article by Conor Pope of the Irish Times

It’s undoubtedly true to say the winter solstice at Newgrange plays second fiddle to another big December day now but it’s equally true to say it was here first and predates the Christmas bandwagon by a good 3,000 years.

There was no denying the festive atmosphere at the site in the hours before dawn on the shortest day of the year as thousands of good humoured folk were shuttled in buses from the interpretive centre to the mound to celebrate a moment marked on this spot for millennia.

Druids and high priestesses carrying yoga mats, dream catchers and drums rubbed shoulders with well-heeled folk in dry robes offering protection from the elements the ancients could scarcely have dreamed of.

Bleary-eyed children were hauled off buses and over wet grass by anxious parents afraid they’d miss their moment in the sun while dozens of people formed human circles and held hands with strangers as they waited for dawn to break over the Boyne valley.

For 17 minutes at sunrise, direct sunlight can enter the monument, not through the doorway, but through the specially contrived small opening above the entrance known as the roof box, to illuminate the chamber.

Ahead of the big day, phone weather forecasts were less than encouraging that would happen this year but the clear skies above Newgrange made it clear technology isn’t always to be trusted.

As the darkness of the longest night lifted, blue skies broke through the gloom and clouds that looked like Celtic swirls floated above a parade of flag carrying, drum-banging Druids who had walked the short distance from Knowth.

A crowd with tambourines and drums gathered as the Druids planted a flag honouring the sun in the soft ground near the mound. Some closed their eyes and swayed to the primal beat while others held their hands in prayer pose and waited for the sun to warm their faces.

A bull terrier called Daisy was at the centre of it all, wagging her tail with a quizzical expression on her face as she tried to work out what on earth was going on and what all the humans were doing. She couldn’t make head nor tail of it all and eventually gave up wondering and went back to playing with her owner.

Daria MacGregor did not need to work out what was going on. She was one of the earliest arrivals and had come from the US state of Georgia via her new home in Wexford.

“It is a magical morning,” she said. “I don’t get up early normally but I’m here because it’s important to honour the land with a community celebrating the same mysterious event. We’re all drawn here and we don’t know why.”

Father and daughter Jimmy and Molly Hennessy from New York knew why they were there. As a family they came to Newgrange last January and were so enamoured, that Molly decided to enter the lottery and was one of just six names drawn out of the hat to be allowed access to the hopefully sunlit chamber.

“I didn’t believe it when my parents told me I’d won,” she said. “I was astounded. I just finished my finals, and we hopped on a plane bound for this spiritual place. I know that the forecast isn’t great but I’m told that more days than not, the sun comes into the chamber, so I’m crossing my fingers.”

The finger crossing worked and while great shards of morning sunshine did not materialise in time to fully light up the passage tomb’s inner chamber, there was enough sun to brighten the room in the most magical and inexplicable fashion.

Kristina Vaughan from Newcastle West in Co Limerick wasn’t in the chamber but she was happy enough on the outside having brought her Brazilian mother-in-law here to mark her birthday.

“We thought it would be a nice way to celebrate. I think it’s a beautiful thing to show her this culture and heritage, on such a poignant day.”

Kira Mack told The Irish Times she was a “high priestess” as she placed a yoga mat and several percussion instruments at a standing stone some 20 metres from the tomb’s entrance.

“This is about the letting go of 2025 but it’s also about bringing back what is ours. The key to life is nature and the sun. I will be drumming as the sun comes up, it creates a special frequency and a vibration.”

Laura Kent from South Africa was also drumming using percussion from her homeland which she’d attached to her legs. She was laid low with a cold last week and while her voice was hoarse to the point of whisper, it would have taken more than an ailment to keep her away. “I was excited like a child last night and woke up at 3am and couldn’t go back to sleep.”

Joan Pires from Goa was “expecting lots of energy and hoping to absorb lots of positive energy. It’s a communal thing where people gather for no particular reason, but with the hope of something. I really like that.”
