Excerpts from Stonehenge Archaeology Analysis Report:
Excerpt i)
‘In contrast to the other trilithons, the internal faces of the Great Trilithon (Trilithon 3) are vertically convex, while the exterior faces are perfectly flat. The exterior faces have also been finished to a very high quality, indicating that the area behind this trilithon was an important location. Indeed, it is no doubt significant that midsummer sunrise can be observed from this point along the NE-SW axis of the monument.’

‘The dressing of the Sarsen Circle is also of significance as it reveals that this is an architecturally complex structure, and not a regular circle of stones as is commonly envisaged. The architecture is orientated around NE-SW axis of the early earthworks and the Sarsen Horseshoe. The stones that straddle this axis have been finely worked to produce regular rectangular portals (Stones 30, 1 and 16; the corresponding edge of Stone 15 is missing), which correspond with that of the Great Trilithon. These breaks in the circle create sight lines towards the midsummer sunrise and the midwinter sunset, depending on which side of the Great Trilithon the viewer is stood; the latter can be viewed from the centre of the circle, while the former is seen from behind the Great Trilithon. Notably both sides of the Great Trilithon are well dressed, in contrast to the exterior faces of the other Sarsen Trilithons, further indicating the importance of both viewpoints. It should also be noted that the inner face of the Sarsen Circle is lined by flat faced stones that have been pick dressed, with the exception of a few more irregular stones that are masked from view if one stands within the Sarsen Horseshoe.’
Excerpt iii)
‘The distinct change in dressing techniques between the Bluestone Horseshoe/Sarsen Horseshoe and the Sarsen Circle is also of particular significance; it is difficult to conceive why these techniques should be different if these elements were contemporary, unless the two groups of stones were dressed by different people. It is, therefore, conceivable that the Sarsen Circle was added to the monument at some point after the Sarsen Horseshoe and early bluestone monument in the Q and R holes was erected.’
