Looks like Stonehenge will be getting a new visitor’s center and some of the encroaching modern civilization is going to be removed. Sounds like a good idea to me. After a lifetime of pretty open access to many Irish megalithic sites, I didn’t realize Stonehenge was kept at hand’s length like this.

A Cursing Stone (c) National Trust for Scotland

A “Cursing Stone” found in Scotland. Not sure why it’s called a cursing stone: a prayer stone would seem to be more apt, at least going by the use described in this article.

The front, or sunrise-facing, wall of Newgrange: white quartz, “river-rounded” granite/aka beach cobbles, and huge greywacke boulders.

We visited Newgrange recently, and paid more attention than usual to the walls of white quartz and “river-rounded granite” cobbles — rounded, gray rocks that look something like cannonballs embedded in the walls — because the day was very windy and we appreciated the shelter of the high walls. I idly wondered why they were part of the construction, what purpose they had, but didn’t have any ideas. Today, I came across an intriguing theory regarding carved stone balls found around large stone circles in Scotland.

More beach cobbles in among the quartz surrounding the roof box.

It seems these stone balls could have served as “ball bearings” when placed in a shallow wooden track, and allowed a relative few people to move heavy stones with economy. The method may have been easier than log-rolling, although the construction of the trackways would have taken time. Perhaps the left-over stone balls could then have been incorporated in the walls of Newgrange? But maybe the river-rounded granites of Newgrange aren’t regular or round enough to facilitate this? It’s hard to tell as they are now part of the walls, and secured in concrete. Some do appear slightly flattened, more like normal river rocks, while others look quite round. They apparently came from a different part of the country to the huge greywacke kerbstones and orthostats used at Newgrange, which raises the question of why these rounded granite stones were used, and not other river-rounded rocks.

The Lia Fail with the mound of the hostages in the background.

Sounds like souvenir hunters chipped off some pieces of the Lia Fail recently. Reminds me of the woman said to have stolen enough rocks from the “Quiet Man” cottage to build a fireplace in her house in the US. It’s a shame as well as a crime. It seems as if we enjoy quite unprecedented access to historical sites in Ireland, and actions like this will only encourage the OPW to control access, and remove what can be removed to museums.

Cairn T, on Carnbane East, near Oldcastle, Co. Meath. The entrance is locked in this picture, but guides are present for much of the summer months.

About 6000 years ago, construction on a large complex of passage graves atop three hills near Oldcastle, Co. Meath began. Most are relatively small (in relation to the famous passage grave sites), although many feature carvings and contain triple (or cruciform) chambers. One of them, known as Cairn T, is illuminated by the sunrise on the spring and autumn equinoxes. The passage is very short, the back of the chamber a mere couple of meters from the entrance, but this tiny chamber is heavily carved, and the slab illuminated by the sun contains many enigmatic images and symbols.

As well as the usual circles surrounded by rays (often thought to represent stars or the sun), and groups of semi-circular lines and various shapes (which some have suggested may be calendars or some form of scale) there are what appear to be child-like depictions of flowers and leaves, perhaps trees. Alright, that’s my own theory; but, given that the equinoxes represent the pivotal points in the natural cycle (spring for planting and autumn for harvesting) it makes sense to me. However, there are probably as many opinions as there are observers, so I’ll reserve judgement until I have a chance to watch the carvings emerge from the darkness with the sunrise on some future equinox.

The rear of the chamber at Cairn T, in the Loughcrew complex in Co. Meath. Somebody seems to have used chalk to better outline the carvings, and the green may be some mold or lichen growing due to the damp conditions in the cairn.

Today, Loughcrew is off the major tourist trail and definitely one of the lesser-known passage grave complexes, but it’s thought that at one time it was extremely important. The hills on which the main cairns are located are called Carnbane East and West; in Irish, that translates as white-cairn. There are walls of white quartz running around some of the fields on these hills, stones that are believed to have been taken from the cairns when the English passed laws requiring the enclosure of agricultural land. As we’ve seen at Newgrange, some passage graves were covered with white quartz, which would have glittered in the sun and drawn the eye for miles around — in the same way that Renaissance Christians built cathedrals to inspire awe at first glance. Perhaps these tombs enjoyed a similar level of importance in prehistoric society?

The blessing of Loughcrew’s relative anonymity is that anyone can show up at sunrise on the equinoxes and watch the illumination take place. It apparently lasts for almost an hour, and as the rear of the chamber is clearly visible from just outside the entrance, there is no need for a lottery to get inside. I hope whoever manages to be there tomorrow morning enjoys the show, and the rest of us can use the equinox illumination as a reminder that it’s time to get on with our planting.

I stumbled across this old article from National Geographic that touches on the theory that Ireland may have been the model for Plato’s tale of Atlantis. Makes one wonder what the original source material Plato was working from contained. We lost so much ancient history when the Library of Alexandria burned. It’s an interesting idea, but not compelling. Would love to see a documentary where these ideas are teased out comparing the text to the archaeological remains.

Peter Jackson could have filmed the Hobbiton scenes around Dowth. It’s that beautiful.

Dowth is one of the three tombs in the Brú na Bóinne world heritage site, situated on a slope rising from the river Boyne near Slane, Co. Meath. In contrast to the other sites at Brú na Bóinne, Dowth is not restored and beautified, but this is a plus as some feel Newgrange and Knowth are a little too well-manicured (and it seems fitting, given that Dowth is derived from Dubhbadh, meaning darkness). Also, access to the Dowth site is free and not controlled via the visitor center. After a morning spent being shepherded around the other two sites, everyone will revel in the freedom to explore Dowth and the ruined churchyard beside it on their terms.

Dowth was once a large mound like Newgrange (possibly of of a taller, conical shape, if old illustrations are to be credited) but amateur archaeologists (although treasure seekers would probably be a better description) damaged the mound severely in the 19th century, and at another point it was used as an easy source of stone for building projects. Miraculously, despite these desecrations, two passages remain intact, although both are tight, cramped and safely locked to keep the public out. (Although you can see some of the carvings inside one of them in this documentary.)

Newgrange as seen from the top of the Dowth mound.

The mound is just off the road; a simple road sign points the way through an old iron gate. Like much of Ireland, parking is on the grass verge along the edge of the road. As you walk along the path towards the mound, the side of the mound that has been dug away is clearly visible. The rim of the mound remains in a horseshoe shape, and the views of the Boyne valley and Newgrange from the top are excellent. Children love to scramble up the mound — but beware of the thick clumps of waist-high weeds growing in the center; these are stinging nettles!

As you walk around the site in a counter clockwise direction, you come upon two low stone-lined entrances, of a size better suited to sheep than humans. (In fact, you’ll probably share the site with sheep, as Dowth, although owned and managed as a heritage site by the state, allows the local farmers’ sheep to graze around the mound — a not uncommon arrangement given the vast number of ancient ruins in Ireland.) These are the entrances to the smaller of the two burial chambers. It’s rather unusual to find two separate entrances to a single chamber; perhaps this reflects a change in burial ritual during the building of all three monuments or perhaps one afforded entrance for people, and the other allowed the passage of the sun for some ritual reason?  Unlike Newgrange and Knowth, which were built to allow people to walk more-or-less standing up, this passage is tiny, designed for crawling only. The chamber is a short distance from the entrance, and you should have enough light to see inside fairly well. Be sure to take a few pictures holding your digital camera , the flash will show detail you miss otherwise. This is one of those times you’ll be grateful you have a flashlight in your pocket.

Like Newgrange, the South chamber is aligned with the winter solstice. However, a recently planted row of trees on the neighboring property are gradually impeding the sun, and will likely eventually block it altogether. At the back of the south chamber is a convex stone which is reputed to reflect the sunlight back against some carvings on the other side of the chamber. As the chamber is locked year-round, I have sadly been unable verify this phenomenon. It should be noted that the roof of this chamber had caved in — a legacy of the quarrying, maybe — and was rebuilt with concrete at some point in the past, so it’s not known how much later interventions has altered the precise layout of the chamber.

The curious aspect about this chamber is that the setting sun illuminates it not just on the winter solstice, but from sometime in November through February. This suggests the sun alignment had some other purpose than simply celebrating the return of the sun at the solstice.

When you’re done looking into these entrances, look over your shoulder and you’ll see a concrete “bunker” at the edge of the field, covered by a thick wire cage. This is the entrance to the second and third passages — one of which is believed to be a souterrain, an underground storage space or place of refuge, rather than a burial chamber. The construction of this souterrain is dated some 2000 years after the construction of the mound and the other chambers.  Only archaeologists get to enter, but most dads and teenage sons like to check out the cage and think about how they could get in “if they really wanted to.”

Continuing to walk around the mound clockwise and you’ll see several large kerbstones peaking out of the lush growth at the base. It appears that Dowth originally had both a ring of kerbstones and was covered in white quartz rocks like Newgrange — now mostly removed for local building projects. On the south side, you come upon a beautiful tree growing out of the slope of the mound. In summer, this looks like something out of the Lord of the Rings, and you half expect to come across a Hobbit hole just past the tree. Instead, you come across one of the most intriguing pieces of neolithic art in Europe, The Stone of the Seven Suns.

Click through to see The Stone of Seven the Suns up close…

Although most of Dowth’s kerbstones are overgrown or buried, Kerbstone #51, known as The Stone of the Seven Suns, has had the vegetation stripped away to reveal what appears to be celestial notations depicting the sun, the moon, and stars. Whether this is some sort of solar calendar, a record of eclipses and celestial movement, or some kind of teaching tool, we simply do not know. One of the seven “sun wheels” appears to show a lunar eclipse in some detail. Significantly, this kerbstone is carved on both sides, suggesting the key to its purpose could have lain more in the act of its creation than in a means of recording or transmitting information. Then again, perhaps the kerbstones where simply an abstract means to beautify the site and please the gods or spirits of the ancestors, or maybe the images on the back were simply a design that went wrong — the chisel slipped and the stone was turned to save the effort of quarrying another? An indentation in the mound has been cut behind the kerbstone to allow people to see these mysterious carvings in full. (There is speculation that this indentation may conceal the entrance to another chamber.) Encourage your children to try to guess at the meaning of the various symbols; their guesses will be as good as anyone else’s.

Across the field at this point, you will see the ruins of Dowth Church, destroyed during the 1641 uprising. A short walk across the fields brings you to the present day Netterville House and the ruins of the church.

The history of Dowth is a fascinating blend of the historically important and the farcically eccentric. The tomb sits on what was once part of the estate of the Nettervilles, an old Anglo-Norman family. When the Insurrection of 1641 began, the then lord, Viscount Nicholas Netterville, allegedly first offered his services to the Crown, but when he (as a Catholic) was not greeted with open arms, he threw his lot in with the rebels. He lost his estates for his trouble, and saw the Dowth church and castle reduced to ruins, but ironically had his possessions restored a decade later when Oliver Cromwell came to power and recent enemies of the crown were recast as heroes.

One century later, the sixth Viscount, John Netterville, built a gazebo on top of the Dowth mound from which he “attended” mass in the nearby church by telescope! In the 19th century, misguided amateur archeologists used dynamite to blow a hole in the mound searching for a fabled inner chamber they thought might contain the lost Ark of the Covenant. It’s not recorded whether these would-be Indiana Joneses found anything they could recognize after their destructive excavation. The heavily damaged site was then used as a quarry for stone for many years, until the mound was overgrown and forgotten.

Oddly, while Newgrange and Knowth have been extensively excavated and restored, little appears to have been done to Dowth other than rebuilding the roof of the south chamber and securing the entrances to the chambers and souterrain. But the contrast between the decay and damage of the ages on one side, and the glorious (if controversial) restorations on the other gives an indication of the magnitude of both the achievements of the restorers and the artistic skill, engineering know-how and organization of the original builders.

As you wander around the overgrown acreage of Dowth, you can draw on the insight gained at the Brú na Bóinne visitor center, inside Newgrange, and around Knowth, to fill in the blanks, to allow the mind’s eye to show you Dowth as it might once have appeared, and ponder what life at this bend of the river Boyne might have been like 5000 years ago.

Knowth (L) and Newgrange (R) seen from the Friary on top of the Hill of Slane. Could an overgrown mound behind the church be the grave of the man who legend says cleared the site for these famous tombs? (Click through for a better resolution view.)

You can wander around the church and friary/college on top of the Hill of Slane all morning without noticing the mound known as “the motte” because it’s in a wooded area behind the church. I know I (who grew up in Co. Meath) didn’t even know it was there until I read about it somewhere or other. There now seems to be a very interesting project to investigate this mound under way. Archaeologists have been scanning the motte and its surroundings (an earth resistance survey) to discover what it’s made of (a cairn of rocks brought from elsewhere, a built structure, or a mound of local clay?) and detect any subsoil evidence of the remains of buildings on top. The resultant 3D mapping gives a great view of the physical features of the hill and suggests future locations to explore.

Going by the annals, it seems likely that there was an ancient grave of some importance on the hill: reputed to be the Fir Bolg king Sláine, from whom the hill gets its name. (Yes, that’s the same Sláine on whose legends the classic 2000AD comic was inspired. I daresay a generation of British and Irish megalithomaniacs had their imaginations kick-started by that story.)  The type of grave this may have been (cairn, passage tomb, dolmen, etc.) we don’t know. Likewise, whether  that grave site was later exploited to build a Norman motte and bailey-type fortified position or whether the church was originally built on the tomb site is unknown. It seems the use of the motte as a fortified position dates from around 1170AD, but the mound now known as the motte could be much older.  Sláine was reputed to have cleared the site for Newgrange, which would place him circa 3200BC.  However, the preliminary earth resistance survey results from this project are intriguing, suggesting that the mound is man-made and revealing a second earthwork (possibly a ring barrow dating from 2500BC–although all dates seem approximate at this stage in the project) partially overbuilt by a rath surrounding the motte. Given the history of adaptive re-use of sites with strategic or symbolic significance by successive cultures in Ireland, there certainly seems to be a strong case for further investigation.

Fieldwork has been ongoing since 2010, so this is a project to bookmark and watch for future discoveries.

“Zombie Skeleton” Photo credit: Chris Read

Lough Key Forest Park in County Roscommon, in Ireland’s North West is a popular place to picnic, a good place to camp and a fixture of boating on the river Shannon. When we were kids our scout troop spent a week camping in the area. However, if I’d known the was a huge ancient graveyard containing at least a few “zombies” overlooking the lake, I might have thought twice about spending the night there.

Two skeletons have been unearthed with large rocks wedged into their mouths (see pic above). The spirit was thought to exit through the mouth, and presumably wedging it closed would have trapped the spirit in the body and prevented it returning to haunt the relatives. So, whether the belief was that the body would become reanimated or just that the spirit would haunt the living is a subject for discussion. But, if this picture doesn’t fascinate and creep you out in equal measure, I’ll be surprised.
