The 12 days of Solstice - Day 12 - sunlight in the passage of Newgrange on the dawn of Winter Solstice


Winter Solstice has officially arrived. Today the sun reaches its minimum declination - its furthest southerly position in the sky. This is the turning point of the year. As the sun rises above Red Mountain in the Boyne Valley this morning (weather permitting), its light will enter through an opening above the passage entrance known as the 'roof box' and will illuminate the central chamber, which lies about 20 metres inside the cairn, for around 17 minutes.  The lucky Winter Solstice Lottery winners will be inside, while hundreds will gather outside. This year, there will be 20 Irish wolfhound dogs at Newgrange too. It should be a great morning.

The photo shows a view taken on Winter Solstice 2010 just as I was emerging from the chamber where I had witnessed the solstice illumination for the first time. As you can see, there are two beams of light. The main area of light, on the floor and the lower part of the passage orthostats, enters through the main doorway. This might have been closed by a large slab during winter solstice ceremonies in ancient times. The upper beam is a much shallower beam, and is visible higher up on the orthostats in the left of the image. This is the light that comes in through the roof box, and it is only this beam that reaches the floor of the chamber within.

As we reflect upon the coming of the glorious light of dawn into the dark void, and the turning of the year, we hope that events in the wider world which have led humanity into darkness in recent times will turn also, and that the hearts of those who have resorted to anger, hatred or fear are softened, so that we can better learn to get along with each other. For that is one of the central themes of the ancient myths involving the Tuatha Dé Danann, the gods who were said to have owned and built Newgrange. When the Milesians came from Spain, to take Ireland by force, there was initially some fighting and, after losses on both sides, the Dé Dananns and the Milesians reached an accord. The Dé Dananns would occupy the sídhe, these great palaces of stone and earth that allowed access to and from the otherworlds, while the Milesians would occupy the surface of the land. And so it is that we must learn to get along with our fellow humans. We must learn to get along together. What is the alternative, except suffering and misery?

Today, as the sun shines into the heart-shaped mound of Newgrange, and warms its interior with a golden light, we ask that a light shines into the hearts of all our fellow human beings, that we might learn to reach an accord that looks to the ending of hate and discrimination, and allows for a peaceful settlement of all conflict. That is the most urgent message from Newgrange for today's world.

The 12 days of Solstice - Day 11 - Winter Solstice sunrise viewed from the doorway of Newgrange

It's day 11 of my new series of photographs entitled 'The 12 days of Solstice'. This is the second-last image in the series. It shows the sun not long after it has risen on the shortest days of the year at Winter Solstice. The picture was taken just inside the entrance of the passage of Newgrange. Above my head in this image is the specially constructed aperture known as the 'roof box'. This is the portal which allows sunlight to penetrate the entire length of the passage and into the chamber. The light that enters through the actual doorway does not reach the chamber floor. The two beams of light are kept separate by the stone seen in the top of this image.

Immediately in front of the entrance is the large kerb stone, K1, which on its front side (the side facing the sun) has the famous tri-spiral design among other lavish engravings. At the time this photo was taken, the sun's light had already left the chamber again. It shines in there for 17 brief minutes. There is something very special about the quality of the light immediately at sunrise. As soon as the sun rises above the ridge known as Red Mountain (Roughgrange), its golden light reaches into the corridor of Newgrange and shines a narrow beam of light onto the darkened floor of its central chamber. It is at this moment that the year is seen to have reached its turning point. The old year dies and the new year is born. Dagda, the father god, yields ownership of Síd in Broga (Newgrange) to his son, Oengus Óg, the youthful sun.

From this moment, following a period of about a week when the sun's rising position has stood still on the horizon, it begins its slow movement back towards the east, and after a few weeks the light will get stronger and the days longer.

Time lapse video - winter evening setting sun illuminates southern chamber at Dowth megalithic monument


It was shaping up to be a lovely time lapse video. I wanted to record the setting sun shining into the southern chamber of Dowth. It's six days until Winter Solstice, and the sky was nice and clear, so I headed out to Dowth with the cameras hoping to catch the illumination of the chamber. As you can see, all was going well, but an encroaching Atlantic front - bringing rain - started to shroud the sun just at the crucial time, and cut off the light, which had begun to reach the chamber floor.

I guess I will just have to try again, if and when the opportunity arises.

Make sure to watch the video full screen and in 1080 high definition. (To do that, press play on the video, and when it starts playing click on the YouTube logo on bottom right. That will open the video in a new window. Then click the full screen and HD settings either side of the YouTube logo).

In the meantime, if you want to see some fantastic photos of a previous winter solstice illumination of Dowth by Anne Marie Moroney, click on this link.

Incredible 3D imagery of the inside of Newgrange allows us to be virtually there for winter solstice illumination

Some incredible images and videos have been created from 3D imagery of the inside of Newgrange. This artist's impression uses a 3D model, created by the Discovery Programme, which allows us, virtually, to be inside the monument. Using this imagery, Seán Doran has recreated the solstice illumination of the chamber, and it's beautiful.

Click the image below to put yourself in the interior of the chamber of this ancient megalithic passage-tomb and see what happens in there on the dawn of the shortest days of the year:


Newgrange Triskele 4K

This gives a good idea what it's like to be standing in the chamber on winter solstice, something only the winter solstice lottery winners can usually do.

Sean tells Mythical Ireland that this rendering project is at an early stage, and that it is very much a "work in progress". Nevertheless, we think it's fantastic. See another render below. In this one, you can click and drag the image to take a look around:


Newgrange equirectangular test
The lighting simulation, according to Sean, is a "brute force Global illumination solve for a light source passing across the roofbox". So the result is accurate in terms of the way light would flow into the passage and chamber, but not necessarily fully accurate in terms of the intensity of light or even the colour. At this stage, the model is completely untextured. That's why I can't wait to see further results!

Here are some still images from the render.  We are very keen to keep an eye on Seán's work as it progresses. There is a huge amount of valuable research going on in relation to the megalithic monuments using very modern technologies. We are, effectively, being allowed to look at monuments in a whole new way.

A view from the rear recess of the light streaming into the chamber, with the triskele visible in the glow.

In these simulations, the famous triskele (tri-spiral or triple spiral) emblem carved into the side stone of the rear recess of the chamber is made visible in the glow. The folklore of Newgrange once suggested this would happen.

The computer imagery puts us right there inside Newgrange.

A glorious dawn announces the beginning of winter as sunrise shines into the chamber of Cairn L, Loughcrew

I was extremely blessed to have been present at Cairn L on Carnbane West at Loughcrew this morning to witness a gloriously beautiful Samhain sunrise and the illumination of the chamber of this ancient cairn.


I hadn't been to Cairn L in a good few years, and to go there in the pre-dawn twilight, with Orion and Sirius looming above the ancient cairns was really something very special. But what was to follow was one of the highlights of many years of being present at ancient and sacred sites. The above video captures the essence of it, but of course nothing beats being there in person. At 7.44am, the sun appeared above the remains of a cairn on the summit of one of the Loughcrew Hills - known as Carrickbrack (from Irish carraig breac, meaning "speckled rock"), and also known as Sliabh Ruadh (Red Hill). One wonders just how ancient some of these place names really are.

Sunlight enters the passage of Cairn L and illuminates the limestone pillar in the chamber.

As the sun appeared, its light immediately streamed into the passage and chamber of Cairn L, where it illuminated a limestone pillar in the chamber - a feature that is unique to Cairn L and not found in other ancient cairns with astronomical alignments.

The stone pillar in the chamber is lit up by the sun at dawn on Samhain and Imbolc.

Martin Brennan and Jack Roberts and their team discovered this alignment in the early 1980s. It is one of many apparent alignments at Loughcrew. The most famous is the equinox alignment of Cairn T (the Hag's Cairn). Although I had been to Cairn L a couple of times, I had never been there at sunrise, and certainly not at Samhain! It was an immense pleasure, and a moment of pure joy and rapture to see the beautiful warm sunlight illuminating the interior of the cairn.

The significance of this event is that Samhain was a very important pre-Christian festival, possibly having its origins in prehistory. It was considered the beginning of winter, and as a so-called "cross-quarter" day, it marks the halfway point, measured in days, between the autumn equinox and the winter solstice. But unlike Newgrange, where the sun shines into its chamber around winter solstice, Cairn L will be illuminated twice - once in early November and again in early February, for the ancient festival of Imbolc, or the February cross-quarter day.

The cairns at Loughcrew were said to have been dropped there by an ancient Cailleach or Garvoge.

In local folklore, it is said that a hag (Cailleach) carrying an apron full of stones created the cairns as she jumped from hill to hill, dropping piles of stones as she did so. Another tale says the hills are sacred to the Garvoge, a "monster woman", who formerly lived here. The following is an old verse, sometimes attributed to Jonathan Swift, about Garvoge and Loughcrew:

Determined now her tomb to build,
Her ample skirt with stones she filled,
And dropped a heap on Carnmore,
Then stepped one thousand yards, to Loar,
And dropped another goodly heap;
And then with one prodigious leap
Gained Carnbeg, and on its height,
displayed the wonders of her might.
And when she approached death's awful doom,
Her chair was placed within the womb
Of hills whose tops with heather bloom.(1)
The moment the sun rose from behind the summit of Carrickbrack.

One cannot help, while looking out from Cairn L towards the other hills (Carnbane East, which was formerly better known as Sliabh na Caillighe; and Carrickbrack), both of which are topped with cairns, of the Paps of Anu or the Paps of Morrigan, and to see in the landscape the earth goddess herself. Perhaps, if one allows a little imagination, one can think of the breasts and the belly of that great woman, so venerated in ancient Ireland, as the earth itself, topped with these cairns that are attributed to her as miraculous works. Ancient though she may be, the Cailleach will never be forgotten at Loughcrew, because the Cailleach IS Loughcrew.

Not among the Newgrange winter solstice lottery winners? Watch this fantastic video of the event


If, like most people, you are not among the winter solstice lottery winners who will have exclusive access to the chamber of Newgrange next weekend, then fret not. Because this fantastic video by Paul Kelly shows the sunlight streaming into the passage and chamber, and it's set to beautiful music that will enchant you and put you into a mystical mood!

As we count down to the shortest days of the year, in a week's time, the light of the rising sun will start to enter the roofbox over the entrance doorway at Newgrange and shine into the passage and chamber. As someone who has witnessed it directly, I can tell you that it is a beautiful moment. Paul's video captures the event marvellously. We thank him for making this very special video.

Fantastic video of solstice sunlight in Newgrange

I'm amazed that this beautiful video showing the solstice sunlight in the chamber of Newgrange hasn't had more views on YouTube. Currently, it only has 112 views. This is the sort of video that is extremely rare, because it's so difficult to get into Newgrange on the solstice and usually only the press photographers are allowed in, and they don't usually do video. This video puts you right in the chamber, at that special moment. There are some shots closer to the entrance too. Really beautiful stuff. Well worth a look.

Ruins on the Hill of Slane

Add caption
The ruins on the Hill of Slane, illuminated by different types of lighting, in the evening glow after sunset. This is the place where, according to tradition, Saint Patrick lit the Paschal Fire in contravention of the laws of Ireland, and in direct view of the King, Laoghaire, who saw the fire from nearby Tara. In earlier tradition, the Fir Bolg king Sláine was said to have been buried in a mound behind these ruins. It is from this king that the modern village of Slane gets its name.

Beautiful Dowth winter shots from Anne Marie Moroney

For some years, a row of evergreen trees growing to the southwest of Dowth has gradually blocked the light from the setting sun at Winter Solstice entering the southern chamber of the Neolithic cairn. However, a couple of years ago, with the permission of the land owner, there was some trimming of the trees which allowed sunlight back into the chamber - with glorious results, as can be seen in these photos, which were taken by Anne Marie Moroney in early January 2011. Anne Marie, author of 'Dowth - Winter Sunsets', has been studying the phenomenon for years.
