Split Stone, Bridge of Allan, Stirlingshire

Standing Stone: OS Grid Reference – NS 81116 99311

Take the same directions as if you’re gonna find the Pendreich Moor cairn up the hills behind and north of Stirling University (there are 2 very close to each other). Once upon the cairned hill, walk dead straight WNW for 100 yards or so, or down the slope into the small valley, then westwards. You’ll hit an overgrown length of very old walling. Keep walking along here and, below it, you’ll find these stones laying down in the shallow grasses on the south-side of the all-but dried stream. The large Cuparlaw Wood cairn is 0.4 miles west of here.

Archaeology & History

This is something of an anomaly. There is no previous written history about the place (that I can find) and archaeologists and historians on The Prehistoric Society and CBA forums can offer no other explanation when asked: is this a standing stone that, many centuries ago, was cut and prepared to be erected, but never made it into the intended monument? (wherever that might have been) And so, I offer it onto TNA and ask the same of any readers, geologists or archaeo’s who might have an explanation for this curious, large split piece of stone, that lays silently on the western moorland edges of the Ochils, asking the same question.

When I first came across this site I was simply perplexed as to the why’s and wherefore’s of who had cut such a large rock into approximate halves. I must have walked around it many times, puzzling what the purpose would have been of doing such a thing, and how long ago the ‘split’ had been performed. About a year later I ventured up again and, when leaving to head back into Stirling, found no resolution to my puzzlement. It had me truly stumped!

It wasn’t until I visited the prehistoric Witches’ Stone about 15 miles away near Monzie Castle last year, that one of those ‘eureka!’ events occurred. The last thing on my mind was the curious split rock above Bridge of Allan. Fellow antiquarian Paul Hornby and I were taking photos of the Witches’ Stone, when one of us remarked how unusually flat and smooth one face of this upright standing stone was – in fact, incredibly flat and smooth – and that’s when it hit me! As I walked round and round the Witches’ Stone, the similarity between this upright example and the one laid on the ground about 15 miles away got stronger and stronger.

A week or two later, archaeology student Lisa Samson and I went back to the Split Stone to have another look at it. Without doubt, the appearance and size and type of rock were one and the same. The only real difference between the Witches Stone and this Split Stone on the edge of Pendreich Moor, is that one stands upright and the other is laid down.

As you can see from the photos, we have a large rock, 5-6 feet long, which was, at some time many centuries ago, split almost straight down the middle, following a natural line of weakness or mineral deposit running through the stone. In all probability this was a standing stone prepared and ready to be used in some neolithic or Bronze Age monument not too far way—but for some reason it never made the journey to its intended spot.

The age of this split rock needs assessing correctly by geologists. Walking around the earthfast halves, it is difficult to see any recent evidence of mason marks that might help us determine when the rock was cut like this. In looking at erosion marks on cut-and-dressed quarried stone from post-medieval periods, we find no equivalent scars on this Split Stone. There is what may be faint evidence of some cuts into the stone at the top and side, but these are very debatable; and very probably it seems that the stone must have been cut a very long time ago, thousands of years back, in order to erode all obvious mason marks. But it would be good to get a geologist to have a look and confirm or deny such things.

…And, as if this isn’t a mystery unto itself: walk across the dried stream and go up the slope right in front of you immediately north. There’s a small, almost level ridge you’ll reach after 30 yards up, before the hill then rises further. If you notice, in the grasses and heather around you, there’s much more of the overgrown ‘walling’ here along this ridge—and some of it, with dips here and there and about three feet tall in places, is in a circle! It’s man-made, it’s a ring of stones, you can see it on GoogleEarth pretty clearly, and it’s not in any official record books.

Follow the same directions as if you’re going to the Corrycharmaig East 3 carving. Walk off the rocky outcrop here, below the tree, and head diagonally across the boggy grasses back towards the River Lochay. After about 50 yards you’ll see a rocky promontory ahead of you that overlooks the very edge of the river, with trees around it. That’s the spot – right on the edge above the river!

Cup-markings on the Corrycharmaig East 4 stone

For me, this was the most intriguing of the newly-found Corrycharmaig East carvings. Intriguing because this is on the same geological ridge as that on which the brilliant Stag Cottage carvings are found, right across on the other side of the river. That singular rise of rock emerging from the field, heading to the river, continues on this side — though is much less conspicuous here, and is much smaller and covered with olde trees and Nature’s marshy greenery. It was this fact which led me to look at these rocks in the first place…wondering if our neolithic ancestors had continued etching their mythographies on the other side of the living waters. And so it turned out.

But don’t expect anything like as impressive as the Stag Cottage carvings. Here instead, as the photos show, are just five distinct cup-markings: three running along one line near the SE side of the stone, with another two on its NW side. The cups are all roughly the same size, being a couple of inches across; one is an inch deep. There may be more beneath the excess of mosses along this and the adjacent rocks, but I didn’t look.

Follow the directions as if you’re visiting the other Corrycharmaig carvings, but as you cross the bridge over the River Lochay, turn immediately left and follow the edge of the river down the field till you reach the fence. Go over here, but then head up the slope away from the river, over another fence up the small grassy hill ahead of you. As you near the very top of the hill, you’ll find the stone in question.

Archaeology & History

Found near to the famous Stag Cottage and Duncroisk carvings, this previously unknown example is found on a small rounded female stone, barely 2 feet by 2 feet across. The most notable feature is the large cup-marking, 2-3 inches wide and half-and-inch deep. When I first found the stone, twas a cloudy grey day and I wasn’t sure whether a small carved arc along one edge of the cup continued into a semi-circle — but as the photo here shows, the cup-mark seems to have a large faint ring going about three-quarters of the way round it. Hopefully I’ll get some better images of the stone when I visit again in the coming weeks.

The stone gave the impression that it belonged in a cairn of sorts, but a brief rummage in the grasses immediately around the rock showed nothing. However, barely 10 yards down the grassy slope there was a small overgrown cairn — though it didn’t seem to have that prehistoric pedigree about it. This carving is one in a group of at least four others—including Corrycharmaig East 3—not previously catalogued. It’s likely that more remain undiscovered on the many other rocks nearby.

Head across the boggy grassland and you’ll see a small green outcrop of rocks just above the tree-line above the river. That’s the spot!

Two of at least 6 cup-markings on these mossy rocks

Another carving that’s a short distance from the famous Stag Cottage carvings on the opposite side of the river. This lovely moss-covered rocky mass has two sections of cup-markings on it – both of which have proved difficult to photograph because of the vivid green primal cover. It’s found less than 100 yards from the CE04 carving and below the hillock of the CE02 cup-and-ring (as you can see in the photo above).

The rock itself has two carved sections: an upper and lower section, with at least three cup-markings on the lower section and three on the upper portion as well. Some natural geological marks on the lower part of the rock may have been added to, but this is by no means clear. There may well be other elements to this ancient carving, but I wasn’t about to strip all the lovely moss from the stone just to find out. It’s a truly beautiful stone in a gorgeous setting and, despite the day being grey and overcast, I wasn’t about to defile the greenery here. It’s one of a group of at least four carvings east of Corrycharmaig that have not previously been catalogued. Other carvings likely remain to be found close by.

Tullibody Stone Circle, Clackmannanshire

‘Stone Circle’ (destroyed): OS Grid Reference – NS 86 95

Archaeology & History

In Alex Wilson’s (1901) rare work he gives the only reference of what may have been a stone circle once found in the township of Tullibody. On a talk given at the Alloa Archaeology Society in the 19th century, the site was mentioned by one of the speakers in his talk on the standing stones of Stirlingshire and district. Mr Wilson told us:

“…at a meeting in November 1871, Rev. Mr Bryson made one of his first speeches before the Society, and spoke of Boulders found in the district, and how these were gradually disappearing owing to the utilitarian spirit of the age. Mr Bryson related how that he had been informed that about 60 or 70 years ago there existed seven or eight boulders round about the Boulder at Tullibody, which Mr Duncan had spoken of.”

This is a brief but intriguing account! Whether we can ascribe the “seven or eight boulders” in the description as merely glacial erratics, or whether the ruins of a stone circle were here as the description seems to imply, we don’t know. If anyone has any additional information they can add to this account, please let us know.

VIVITAR DIGITAL CAMERA — Deep cups on this Woofa Bank carving

Follow the same directions as if you’re gonna visit the Idol Stone carving. From here, keep walking uphill until your reach the rocky crags on the slope above. Go left (southeast) along the small footpath that runs along the top of this ridge for 350 yards (320m) and, where the path begins to very gradually slope back downhill a little, go sharp left, downhill for 50 yards, where a couple of large rocks stand out. Before one of these, low down in the heather, you’ll find this curious cup-and-ring stone.

Archaeology & History

This is a lovely cup-and-ring stone, seemingly recorded for the first time by fellow rock-art student Stuart Feather (Radford 1968) in one of his numerous ramblings over these moors. It’s a difficult habit to break once the bug bites! The rock itself is unusual, possessed of undulating geophysical waves or ripples across its surface, similar to a cluster of others a couple of miles west near the very top of Rombald’s Moor. The curvaceous feature alone would have given this stone a spirit-nature of its own, different from the others in this area — though we may never know what that might have been.

CR352 dr — Primary design (after Hedges)

The cups carved onto this rock are cut much deeper than most other prehistoric carvings along this ridge and, for some reason or other, give an immediate impression of having been painted and coloured in lichens or other natural dyes, to encourage or awaken the mythic history within and around the stone. It’s a formula that occurs worldwide and needs serious consideration, not just here, but at many other outcrop carvings in Wharfedale and much further afield.

The carving was described in John Hedges’ (1986) fine survey as a,

“Fairly small flat rock, level with the ground, sloping slightly in heather and crowberry, its surface layered in waves which appear to have been incorporated in the design which covers the rock. About 25 cups, some very deep and some showing pick marks, three are enclosed in rings, one of which has three cups in its circumference and a groove leading from it to edge of rock.”

Many other carvings scatter the moorland plain of Woofa Bank — some recorded, others not — in a region rich in Bronze Age and probably earlier cairns. We’ll add all their profiles here as time floats by…

Cup-Marked Stone: OS Grid Reference – SE 1380 4521

Archaeology & History

One of this regions many simple cup-marked stones, this example is another that is not in the archaeological records as it was rediscovered on March 1, 2012, by one-time rock art student, Michala Potts of Keighley. Found in association with one of the many prehistoric cairns in the landscape, it is a small flat rock, that was mainly covered over in dead bracken remains. There are two very distinct archetypal cup-marks etched on the westernmost half of the stone, with a possible faint third in-between the two. The larger of the two cups measures 2 inches across and is a half-inch deep; the other cup being 1½ inch across and roughly the same depth. Several other cup-and-ring stones can be found close by.

The curious-looking inverted ‘F’ beneath the two cups is somewhat of a dilemma, as part of it appears to have been carved and has the hallmark of a typical boundary marker. However, the top line is almost certainly a natural feature on the rock, but the vertical and second horizontal line may have been cut into the rock at a later date. There are remains of some medieval workings just 10 yards away from this stone, which may account for the enhanced lines; but we could do with a decent geologist to have a look and tell us one way or the other!

Witch’s Stone

Archaeology & History

This fascinating looking carving (in my personal Top 10 of all-time favourites cup-and-rings in the UK!) was unfortunately destroyed sometime between 1918 and 1920. A huge pity, as the design on the rock is almost unique in its ‘linear’ system of cups running a considerable length across the surface of the stone (like the similar design found at Old Bewick in Northumberland).

Witchs Stone, Ratho (Wilson 1851) — Wilson’s 1851 drawing of the Witches’ Stone

Witchs Stone (Simpson 1867)sm — Simpson’s 1866 drawing of the Witches Stone

Shown first of all on Kirkwood’s Environs of Edinburgh map in 1817 (above), this legendary rock was found amidst a cluster of other cup-and-ring stones at Tormain (some are still there) and was initially said by Daniel Wilson (1851) to have been the giant capstone of a cromlech that once stood here, but whose structure had fallen away. This idea is implied in the earliest drawing we have of the stone in Wilson’s magnum opus (above); Sir J.Y. Simpson (1867) gave us a similar impression with his drawing a few years later. But upon visiting the Witches Stone just as his book was going to the press, Mr Wilson visited the site and proclaimed that he “altogether doubted if they are the remains of a cromlech”, and what rested here were more probably just fascinating geological remains, with even more fascinating carvings on top!

In the years that followed Wilson’s initial description, the Witches Stone was visited and described by a number of eager antiquarians. Simpson (1867) gave us a quite revealing account, telling:

“On the farm of Bonnington, about a mile beyond the village of Ratho…are the remains of ‘this partially ruined cromlech’…with the capstones partially displaced, as if it had slid backwards upon the oblique plane of the huge stones or stone which still supports it. Two or three large blocks lie in front of the present props. Its site occupies a most commanding view of the valley of the Almond, and of the country and hills beyond. The large capstone is a block of secondary basalt or whinstone, about twelve feet long, ten in breadth and two in thickness. Its upper surface has sculptured along its median line a long row of some twenty-two cup-cuttings; and two more cup-cuttings are placed laterally: one, half a foot to the left of the central row and at its base; the other, two feet to the right of the tenth central cup and near the edge of the block. The largest of the cups are about three inches in diameter and half an inch in depth; but most of them are smaller and shallower than this…”

A few years later another early petroglyph authority, J. Romilly Allen (1882), visited the Witches Stone and found “an Ordnance bench mark (had been) cut on the stone itself”! He then continued with his own description of this once-important megalithic site:

“The Witch’s Stone is a natural boulder of whinstone, rounded and smoothed by glacial action, whoso upper surface slopes at an angle of about 35° with the horizon. The length of the sloping face is 8 feet and at the top is a flat place 2 feet wide. The breadth of the stone is 11 feet 3 inches at the upper end, and 4 feet at the lower end. The thickness varies from 2 to 3 feet. The highest part of the stone is 6 feet 6 inches above the ground, and the lowest 1 foot 6 inches. It rests on what has originally been a portion of the same boulder, but is now a mass of whinstone broken up into several fragments, which serve as supports to prop up the stone above. Viewed from the north side the whole presents the appearance of a cromlech, the upper stone forming the cap, and the disintegrated portion below the supports. This notion, however, will be clearly seen to be erroneous on looking at it from the opposite side, as shown on the accompanying sketch…where the crack separating the two portions of the boulder is very apparent… The sculpturings consist of twenty-four cups varying in diameter from 1½ to 3 inches. Twenty-two of these cups are arranged in an approximately straight line along the sloping face of the stone, and divide it into two almost equal parts. The two remaining cups lie, one 7½ inches to the left of the lowest cup of the central row, and the other 2 feet 3 inches to the right of the ninth cup up the stone… The field in which the Witch’s Stone is situated is called “Knock-about.” The sloping face of the stone has been much polished by the practice of people climbing on to the top and sliding down. Some of the cups are almost obliterated in consequence. The stone forms a very prominent feature in the view, and must always have attracted attention from its peculiar shape.”

Some twenty years after Allen, the megalithomaniac Fred Coles (1903) came and checked the Witches Stone out for himself and, as happens, had a few additional things to say about the place:

“Although this huge boulder and its cup-marks have been more than once figured and described, I found, on a close examination of the broad surface of the Stone, that none of the illustrations showed the cup-marks in their exact relation to each other, nor in their true relation to the contour of the Stone. The drawing shown above…was made after a careful measurement by triangulation of the Stone; and it is claimed to be the first that shows that the cups, two and twenty in number, are not disposed in one continuous line, but that thirteen follow each other from the high south edge of the stone for a distance of exactly 6 feet, and nine others lie a few inches to the west, occupying a space 3 feet long of the overcurving edge of the north end. It is further shown that, at a point 2 feet 3 inches west of the ninth cup-mark, there is another one quite as large as the largest in the rows near the middle of the Stone. The south edge (A B) has slipped a little down from its original height, the boulder being frost-split horizontally; its height there above ground is 8 feet. The northern and narrower end is about 2 feet above ground, and does not touch the ground, as it rests upon its lower portion, beyond which it projects a few inches. The cup-marks run due north.”

Witchs Stone (Coles 1903) — Fred Coles 1903 drawing

If the Witches Stone was in fact a natural outcrop stone and not a cromlech, this very last point telling that “the cup-marks run due north” probably had much greater importance than a mere compass-bearing to the people who etched this carving. For in pre-christian religious structures across the northern hemisphere, north is commonly representative of death and the land of the gods. In magickal rites “it is the place of greatest symbolic darkness,” as neither sun nor moon ever rise or set there. Additionally, north is the place where, in shamanic traditions, the heavens are tied to the Earth: the cosmic axis itself that links heaven, Earth and underworld. In early neolithic traditions this mythic structure was probably endemic. Whether its magickal relevance was intended here, at this stone, we will probably never know…

Folklore

Folklore tells that the Witches Stone was one of the sites used in magickal rites by the Scottish occultist, Michael Scot. J.R. Allen’s (1882) description of “the sloping face of the stone has been much polished by the practice of people climbing on to the top and sliding down,” may relate to folk memory of fertility rites once practiced here, as found at similarly carved rocks in the UK and across the world.

Go thru Killin and, just past the Bridge of Lochay hotel, take the tiny road on your left. Go down here for 3 miles till you pass the gorgeous Stag Cottage (with its superb cup-and-rings in the field across the road) for another 300 yards, until you see Duncroisk Farmhouse set back on your right. On the other side of the road, go thru the giant deer-gates (close ‘em behind you) to the river-bridge and across it. Walk along the track till you reach the turning to Corrycharmaig House on the right (over the stream), but here, go up into the field thru the gate. Walk up the hill ahead of you with its trees on the left, walking up onto the grassy level, over the deer-fence, then up again to the rounded knoll another 100 yards up. You’re here!

Archaeology & History

On my first visit to this stone, in overcast and wet conditions — the easternmost of at least four separate carved rock faces along the same geological ridge — I only noticed a handful of cup-marks etched onto the northeastern section of the stone. But I was sure there were supposed to be more. And when I returned home to check up, found that Ron Morris (1981) said there were “40 widely scattered cups of which, however, 29 well-defined cups are in a compact group, of which 6 are in a line.” Much more than what I saw! And when I checked further, it was evident that even more cup-marks were once visible on the rock. In the very first description of this carved stone, E.A. Cormack (1952) told:

“On the easterly area there are about 70 small cups, roughly one inch in diameter, in groups of ten to twelve. Most are on the flatter rock surface, but some are on the steeper slope facing south, which also bears the marks of deep glacial scorings.”

Corrycharmaig1 — A sample of cups on ‘Corrycharmaig 1’

So on our visit here again a few weeks ago when we stayed at Corrycharmaig house*, a couple more visits allowed a slightly better investigation, albeit in even wetter and cloudier conditions than our first visit! And the more we looked, the more we could see; and it was plainly evident that a number of cup-marks had become receptacles for moss-growth! We counted at least 40 cup-markings on this ‘Corrycharmaig 1’ stone, but it seemed pretty obvious that beneath the grasses and vegetation, more carvings would be found.

Walking SSE along the same rocky ridge brings you to the other rock faces of Corrycharmaig (2), (3) and (4) — all with their own carvings. Corrycharmaig 2 possessing the only known complete cup-and-ring on the ridge. More carvings remain hidden nearby…

Getting Here

Follow the same directions to get to the Corrycharmaig 3 carving; and just a yard or two to the right of the far western edge of the rock, you’ll see another smaller slightly sloping rock, closer to the fencing, with faint cup-markings. That’s the one! (note that the 10-figure grid reference given here might need adjusting slightly)

Archaeology & History

This small slightly sloping piece of exposed rock is on the western extremity of the Corrycharmaig cluster of carvings, but is a distinctly separate piece of rock from the Corrycharmaig 3 stone (though part of the same outcrop). The stone itself has two sections to it, with a natural crack in the rock defining eastern and western section — both of which possess cup-marks.

The easternmost section of the stone has seven cup-marks, some of which were only recently uncovered. A large single cup-mark sits near the middle of this portion of the rock; this is probably what Mr Cormack (1952) was talking about when he told that, “further west (of the Corrycharmaig 3 carving, PB) is one isolated larger cup of 4-inch diameter.” On the western side of the stone, we find just two or three cup-marks, though one large cup-marking here would seem to be Nature’s handiwork.

It is highly likely that beneath the excessive vegetational growth around this carving and others along this ridge, other sections of prehistoric carvings remain to be found.
