Stonehenge Riverside Project.
Early excavations at the Cuckoo Stone.
It is suggested that.....The rectangular mark centre, is a Roman mini metalworking area and will not be excavated.....The small square above it is a modern test pit......The dark area to the right of the stone may be the ramp used to raise it....the parallel lines are plough marks.
Other obvious traces are a mystery.
