Stonehenge: circle of parchmarks identified outside sarsens between Y and Z holes @AntiquityJ bit.ly/1mSDIJC
Win has spotted the surprise finding of the Antiquity parchmark paper - that maybe there are more circles at Stonehenge...
The conclusion of the paper is: “The new discoveries do tentatively allow further consideration of the multicircuit post settings envisaged by Gibson (1998: 41-44) and comparison with Woodhenge and the Sanctuary as well as Stanton Drew (David et al. 2004) but in the absence of dating evidence this remains speculative. The more diffuse marks around the periphery of the site might offer support for Pitts’ (1981) suggestion of an outer ring of stones. However, again, more research is needed to clarify this issue. This emphasises the potential for new discoveries about Stonehenge (one of the most widely researched monuments in the world) through non-invasive as well as invasive techniques.”
I can't share the plans yet so here is one of some other circles instead...
