ND48SE 1 4704 8449

ND 469 843: An Orkney-Cromarty stalled cairn, in uncultivated ground about 220' from precipitous cliffs and about 100' OD. The cairn has a thin skin of turf over the stones, but has been much robbed except for part in the centre of the W side which is still about 10' high. The edge of the cairn is difficult to define; its length is about 135', its width about 50', with the long axis running N-S. Partial excavations were carried out by Ritchie in 1958, and have been filled in; the description is taken entirely from the report.

Two wall faces were exposed in the body of the cairn at the N end. They run transversely to the axis of the cairn, are built of horizontally laid slabs, and retain a height of 3' 3". Forty-two ft NNE of the N end of the chamber, a small orthostat projects through the turf, and excavation exposed a wall face of one or two courses stretching for 5'8" in a SSW direction.

Excavation revealed the northern part of a stalled chamber of at least four compartments, but its S end was not traced. The N end compartment alone was fully excavated. It is 3'8" long, 5'9" wide, and the wall stands 4'8" high. The next compartment measures 6'3" by 4'6", with the side walls 5'2" high. The third compartment is about 7'3" long. In the middle of the W wall of the second compartment was the entrance to a side cell, roughly 4'6" square and about 3' high. Opposite this entrance is another entry, probably the end of the entrance passage. This entrance was filled with earthy material and bones. The entrance to the cell and the cell itself was not filled up.

Finds from the site, in the National Museum of Antiquities of Scotland (NMAS), include: three stone axes, a mace head, a polished stone knife, a cylindrical bone bead, a V-bored jet button and four pottery sherds, one probably from a carinated bowl. The skeletal remains included skulls representing thirty individuals and some human and animal bones.

The remains of a chambered cairn at ND 4704 8449; the E half of which has been completely eroded away exposing four slabs of the stalled chamber. The W half of the cairn is represented by a turf-covered mound of debris c.2.5m high, which appears to be two-tiered, suggesting that originally the cairn stood on a platform, although this appearance could be due to uneven slip or other disturbance. The effect, however, is of a distinct berm around the base of a probably originally circular mound which has been approximately 22.0m in diameter, with the platform possibly measuring about 40.0m overall.

The small orthostat to the NNE survives in situ, but there is no trace of the walling to the SW seen during excavation.

Surveyed at 1:2500.

Isbister, O-C round with projections: Since the last report, the cairn has been further excavated in 1976 and 78 by Mr R Simison, the landowner, in collaberation with NoSAS and IAM, revealing much of the chamber and part of the hornwork to the N of the cairn.

The cairn is estimated as about 15m in diameter and still standing c2.9m high. An entrance passage runs from the ENE at right angles to the axis and from the centre of the chamber, and survives for a length of 4m, 0.7m wide, and is still roofed at the inner end by a massive lintel at a height of 0.85m.

The chamber is 8.2m long overall, divided into five segments by three pairs of transversely-set orthostats which project only about 0.1m from the walls and so do not form stalls in the usual manner.The two end compartments are distinct from the central portion of the chamber. The latter is 6m long by 1.2 to 1.6m wide with drystone walls 2m high without corbelling. There are three side cells entered from the N and S ends of the W side, and from the N end of the E side of the chamber.

The end compartments measure about 1.8m wide by 1.2m deep, thus at ground level are wider than the central portion of the chamber. Each has a slab set on edge c.0.3m high across the entry. The backs of the compartments are formed by a vertical slab. A flagstone shelf is preserved in the S compartment about 1.2m above the floor and in the N compartment part of a similar shelf remains about 0.2m higher.

The side cells are entered by passages c.0.7m long by 0.5m wide and 0.7m high, each roofed by a single lintel. The floor areas are irregular in plan, being 1.5 to 2m in length, and roofed at a height of 1m by single capstones.

Part of the outer wall-face of the cairn is exposed on the NE for a length of about 10m and is 1.9m high above a level-projecting base of one course 0.1m high. On each side of the passage, an inner revetment wall is visible 0.9m high, and a third wall-face runs from the passage curving to approach close to the S end of the chamber. To the N of the passage a wall face at a different level is built round the back of the NE cell. The projecting 'horns' to the N and S of the cairn form a shallow forecourt c.110m across. Part of the N 'horn' has been exposed revealing a double-skinned wall 1.5m wide robbed to only 0.3m in height, and abutting against the N retaining wall of the cairn showing that it is later in construction.

The chamber is clearly not in the centre of the mound which measures overall some 27m, and there may be a second chamber to the W of the excavated area.

Human, animal, bird bones and skulls, as well as Unstan pottery, were found, and the extraordinary high proportion of white-tailed eagles talons suggests a symbolic purpose for the tomb. Tentative dating places the tomb as built c.3250 BC and in use until c.3000 BC.

Planned further trenching in 1982-3 by Mr Simison has exposed other feature of the cairn.

1. On the W side a trench has revealed the uppermost courses of a wall-face at a height of about 2.5m above the chamber floor - at the highest part of the mound before this excavation. This, together with the exposed wall-face on the N, suggests that the chamber stood centrally within a cairn measuring c.16 x 11m.

2. Other trenches in the N, NW, SW and S have revealed a double-faced wall c.2m wide enclosing the cairn mound. At the N end this wall stands on redeposited material, and attains a height of 0.75m; it is assumed that it butted against the 'hornwork' wall which is thought to be an earlier feature although later than the cairn itself. About 2m W of this junction there was a gap in the wall spanned by a large lintel - now removed.

On the W side, the curving wall is 0.5m high, and reduces at the S end where the ground level rises, to only 0.25m high in two surviving courses. The cairn body rises from this wall, and also extends beyond it probably due to slip from the cairn mound.

Since 1981 it has been recognised that the postulated 'hornwork' on the S is a formation of natural rock under turf, and there was probably no wall built upon this to compliment the N wall. Also, the top of Ritchie's 2nd wall-face was noted in 1984, having been covered over in previous years.

Information from J L Davidson, 29 May 1984.

In 1987 guardianship of the tomb was received by Orkney Islands Council. They initiated a programme of archaeological excavation, consolidation and building works to display the site to the public. Partial excavation of the tomb masonry was necessary to house the foundations of a concrete roof for the central chamber. The walls were built up to meet the new roof and then the whole was covered with soil and grassed over. The excavation uncovered details not discovered during previous excavtions.

The excavated details have been preserved where possible and the entrance area has been partly rebuilt. Slate was used to mark the boundary between old and new masonry. Floor deposits in the main chamber and side cells has been left intact and reconstructed funeral deposits have been left in one cell to aid the visitor's understanding of the site.
