We don't know what it is yet . 7-9 sockets that may have held bluestones
and if they did may have been part of a more circular feature none of which remains .There is a bit of a surrounding ditchand bank that may be a henge . The ditch may be dated due to the antler finds but the sockets only have charcoal supposedly a later deposit after the stones were removed (if they existed in the first place ) .If it was a stone circle the lack anything funerary or deposits makes the connection with the" stone for the dead , wood for the living" idea look a bit creaky . The RC dates will be crucial but lets hope the resulting interpretation is not too far fetched .
