As mentioned in the ‘Art and Archaeology’ page, the set of rock outcrops that collectively form the Carn Menyn ridge include a “promontory”, a spur of the outcrops that juts out to the south.
The S.P.A.C.E.S. project, led by Geoffrey Wainwright and Timothy Darvill, located a quarry, probably Neolithic, in the north-west corner of the promontory, and discovered that the neck or entrance to the promontory was marked by a prehistoric earthwork boundary, suggesting that it was denoted as a sacred space. It was decided to make this one of the zones of intensive visual and acoustic study at Carn Menyn.

This line of rocks sits on an earthen berm that extends to the big rock at right in this picture, and goes on beyond it, providing a boundary or temenos across the entire neck or entrance of the promontory which extends off-camera to the left
In the central area of the promontory is this large block of rock, which has a vulvic-shaped hollow in its top, seen here filled with rainwater. Could this ‘mother rock’ have been one factor that signified the sanctity of this promontory to the Neolithic people of Carn Menyn?
Exploring the jumbled, partially collapsed ‘quarry corner’ in the north-east of the promontory
Testing for lithophone properties amid the jumbled remains of bluestones in the quarry corner of the promontory. The project found that overall lithophones comprised about 10 percent of the rocks along the Carn Menyn ridge, but at a few spots, such as here at the quarry, that rose to 40 percent or more. This could have been another reason the promontory was venerated. The audio clip here gives the sound of just one of the ‘quarry corner’ rocks

An investigator leans against a fallen or dropped bluestone pillar in the promontory quarry area that may have been abandoned by the Neolithic megalith builders for some reason after being originally destined for Stonehenge. The pillar is a lithophone
