Type: Probably remains of a square setting Length: 24.85m
No. of stones: 8 Size of stones: Only large
Orientation: 169° Altitude: 160m
Upper end: – Lower end: –
Straight (Yes or No)  : No Sea View: No
Context:  Henge, stone circles, stone rows and standing stones

Notes: This line of stones has the appearance of a stone alignment but a geophysical survey has suggested that it much more likely to represent the remains of a square setting. The only other example found inside a stone circle is at Torhouseskie and perhaps future work there will result in a revision of the current interpretation.

Other Information

Public Access:  Yes
Land Status: National Trust
Scheduled Ancient Monument: Yes


Category: Unlikely. This line of stones look like a stone row, but other excavated features in the vicinity and results from a geophysical survey indicate that this structure originally probably formed part of another feature.

Compared to the massif sarsens forming the surrounding circle the stones in the feature are comparatively small. View from south east.

The stones vary in height.

Looking Towards Silbury Hill

The following eight photographs are taken in sequence from the north to south from each stone within the feature looking towards Silbury Hill. As one walks south along the feature, the top of Silbury Hill appears to glide eastward along the top of Waden Hill disappearing behind and re-appearing from behind a large sarsen forming part of the South Circle. 

View from northernmost stone. Silbury Hill is visible beyond the lower slope of Waden Hill. The henge bank would have originally been higher at this point and may have originally formed the lower visual block. A stone forming part of the Great Circle seems to point at Silbury Hill.

View from next stone. Silbury Hill remains visible and from this point appears to have moved to the left of the Great Circle stone and towards the large South Circle stone.

View from third stone. Silbury Hill is now framed by the near South Circle stone and the Great Circle stone.

View from fourth stone. Half of Silbury Hill has disappeared behind the large South Circle stone.

View from fifth stone. Silbury Hill has vanished from sight.

View from sixth stone. Silbury Hill remains hidden from view.

View from seventh stone. Silbury Hill appears from behind the large orthostat.

View from southern stone. Silbury Hill is now perfectly aligned with an orthostat in the Great Circle and the site of another stone marked by a concrete bollard.

The southernmost stone of the feature is visible in the foreground. From this angle it is possible to appreciate the way in which the end of the feature is provided with a sign-posted ,focused view of Silbury Hill. That this alignment exists today is without question, whether it existed in the past is less certain, but if it did, there is a strong likelihood that it was deliberately contrived.  In common with most stone rows, the Z feature at Avebury appears to have been constructed to provide access to particular visual treats.  

Access Information

Car parking is provided at a price at SU 09959 69653, but access to the stone circles, henge and Z feature is free. From the car park head into the village and make your way to the centre of the henge.
