RCAHMS Community Engagement 2013

This ring-cairn is situated 200m SSW of Easter Delfour, close to the leading edge of a natural SE-facing terrace overlooking the flood plain of the River Spey. It originally consisted of a ring of orthostats enclosing a ring-cairn revetted by an outer platform, but, today, only one orthostat from the surrounding circle still stands. It remains vertical and firmly set, although it is located in a hollow 0.2m deep worn by cattle rubbing against its flanks. It measures 1.55m in breadth by 0.35m in thickness and it stands 2.65m in height; and while its broad flat faces are distinguished by quartz nodules and veins beneath lichen, its sides taper upwards irregularly to form a blunt point. The stone is positioned 7m SW of the ring-cairn where it marks the focus and axis of the monument that passes NE through its centre; and its distance from this centre indicates that the monument once had a diameter of 32m. There are fragments of four additional slabs that may also derive from this circle. The best preserved is situated at the foot of the platform to the W of the ring-cairn. Although a straight edge on its E reveals that it has been cut down, it measures 2.4m long by 0.65m broad and 0.18m thick. The other fragments are smaller and their identification is less secure. One is a slab which has been cast into the body of the ring-cairn immediately NNW of the central court. It measures 1.5m long by 0.6m broad and 0.2m thick; while another, shaped rather like a parsnip and measuring 1.1m long by 0.55m broad and 0.45m thick, is situated at the edge of the stony matrix 2m to its N. The third slab is situated on the S side of the cairn 1.2m E of a boulder bearing a drill hole made to hold a charge of gunpowder. It measures 0.9m long by 0.68m broad and 0.25m thick.

A grass-grown stony bank or platform retains the exterior of the ring-cairn. It measures 2.5m thick by 0.8m high on the SE, where its original sloping profile is best preserved. However, it has been damaged by ploughing around much of its circuit and it has been completely destroyed on the WSW, where a point of entry has been driven into the heart of the monument to allow carts or barrows access in order to facilitate stone robbing. The ring-cairn, itself, is polygonal on plan and measures 18m in diameter. Its outer kerb is formed from carefully chosen, closely fitted, rectangular slabs set vertically, their summits now largely projecting above the top of the platform. However, their irregular shape and the variable alignment of their broader faces would have been concealed by the outer platform and the cairn’s stony fill. Small vertical slithers have been used to fill gaps between them at four points on the W and one on the E. The kerbstones are roughly graded to diminish in size from SW to NE, with the result that the larger and taller contrast with the smaller and shorter embedding the monument’s axis. The largest stones of all are situated next to one another 7m NE of the one surviving orthostat which also projects this axis. They have been deliberately paired to offer a contrast. Thus, the stone on the NW, which is a rectangular slab with a flat horizontal upper surface, measures 1m high by 1.3m broad and 0.5m thick, while the stone on the SE, which is notably dome-shaped, measures 1.3m high, 1.2m broad and 0.6m thick. Yet, despite these statistics, they can be characterised respectively as ‘slender’ and ‘stout’. Most of the outer kerb is intact, save on the SW where at least one stone has been removed to either side of this pairing. However, one on the S has been displaced, while another on the NE is reduced to a low stump with its upper section lying prone immediately to the E. The matrix of the cairn has been largely removed from the interior leaving the footings of the outer and inner kerbstones exposed. However, there are drifts of large water-worn cobbles on the N which overlap the top of the outer kerb in that quarter and there are others on the NE and SE. These include a small admixture of field clearance, but elsewhere grass-grown cobbles can still be detected underfoot. Two rectangular cuttings from an unrecorded archaeological excavation post-dating the stone robbing are situated on the ENE and ESE. Both have been restored with boulders. The central court of the ring-cairn, which is also polygonal on plan, measures 7.5m in diameter. It is delimited by carefully chosen, closely fitted rectangular slabs, but unlike those of the outer kerb these have been deliberately set to lean outwards to counteract the pressure of the cairn’s stony matrix. Their inner faces are also notably smooth and regular, indicating that the court itself was probably once open and free of stone, although a recent gathering of boulders measuring 2.5m in diameter and 0.7m high now occupies the centre. There is one instance on the E where a gap between two of the kerbstones has been filled with a vertical slither; but slabs are missing from the kerb’s circuit on the SE, SSW, WSW and N. As with the outer kerb, the stones are roughly graded to diminish in size from SW to NE to reinforce the axis of the monument. The largest, situated on the SW immediately NW of the axis, measures 0.85m high, 0.53m broad and 0.32m thick. This now lies snapped in two immediately SW of the stump, but its detached upper section exhibits a flat horizontal upper surface.

The axis and focus of the monument’s architecture indicates that it was carefully orientated to point towards the SW quarter of the sky where the sun would set at midwinter. The contrast in the shape of the two large stones marking the axis in the outer kerb on the SW possibly symbolises a closed entrance, which was itself subsequently sealed symbolically by the encircling revetment.

The Rev John Macdonald’s account indicates that the stone circle had reached its present state by 1835, but the condition of the ring-cairn at that time is less certain although the inner and outer kerbs were evidently plainly visible (NSA 1845, 87). The monument was surveyed in 1869 for the 1st edition of the OS 25-inch map, when it fell near the centre of a rectangular field laid out from NE to SW (Inverness-shire 1875, sheet lxxiii.9). The OS differentiated the ring-cairn from the orthostat, describing the former as a ‘Stone Circle’ - adding the comment in the Name Book that it was ‘covered with loose stones which renders it impossible to define the position or number of stones composing it. . .’ - and the latter as a ‘Standing Stone’ (Name Book, Inverness-shire, No. 4, p5). However, Alexander MacBain recognised Delfour as being one of a cluster of monuments in Badenoch and Strathspey that had strong affinities with the Clava Cairns (MacBain 1885). Each consisted of an outer ring of graded orthostats enclosing a ‘ring cairn’ – the term which Sir Arthur Mitchell had first employed in describing the cairn within the comparable monument at Grenish (Mitchell 1874, 685-7) and which MacBain also identified as a member of this group (NH91NW 5). There is no change in the OS depiction of the two elements on the 2nd edition of the 25-inch map (Inverness-shire 1901, sheet 073.09), but Caleb Cash’s plan of 1906 indicates that the NW arc of the ring-cairn’s outer kerb remained buried beneath field clearance, while the inner kerb was entirely lost to view (Cash 1906, 252-4). Cash was also assured by an informant that the monument had not been disturbed for at least thirty five years. His plan shows the broad gap through the outer kerb made to facilitate stone robbing, confirming that this destructive episode must have occurred before 1870 and possibly very much earlier. It is not known when the field clearance was finally removed, or when and by whom the excavation cuttings were made, but the detailed plan taken by Audrey Henshall and J. C. Wallace in 1957 shows the monument with this stripped away (Henshall 1963, 374-5). It is accompanied by an excellent description and unlike earlier commentators Henshall reaffirmed MacBain’s view that the orthostat was the survivor from a surrounding stone circle. Alexander Thom’s plan of 1958 was taken to evaluate the monument’s astronomical and geometric properties (RCAHMS DC4436 (B7/10); RCAHMS MS430/28; Thom 1967, 86-87, 98; Thom, Thom and Burl 1980, 256-7; Ferguson 1988, 96). He recognised the orthostat as a ‘solstitial outlier’, but was much more exercised by the ring-cairn for which he inferred a complex geometrical composition. However, Burl firmly rejected this last deduction, arguing that its geometry was as likely ‘the result of haphazard construction as of nice mathematics’ (Burl 1976, 43-4). Nevertheless, he accepted Thom’s astronomical interpretation and included this in a general analysis of the properties of Clava ring-cairns (Burl 1981, 258-61). More recently, refocusing on Thom’s perception of the standing stone as marker of the winter solstice, he has questioned whether it should be interpreted as the solitary survivor of a surrounding circle rather an outlier (Burl 1995, 132; 2005, 132). Delfour has also been reassessed by John Barnatt, Audrey Henshall and Graham Ritchie, and Douglas Scott, but none has offered any new observations (Barnatt 1989, 260; Henshall and Ritchie 2001, 9, 13, 16, 17, 240; Scott 2003, 103).
