About a kilometre to the west-north-west of The Hurlers lie the remains of a stone circle. Sited in an area of gently sloping rough moorland pasture, the Craddock Moor stone circle consists of sixteen or seventeen stones, all fallen and some broken. A detailed site survey suggests that there may originally have been 26 or 27 uprights, but as a result of intensive peat working and quarrying in the vicinity, it is not now possible to be certain about the original design and layout of the site.
An amateur astronomer could have finally unravelled the mystery of the ancient Hurlers on Bodmin Moor. The three stone circles in Cornwall have been discovered to align perfectly with the constellation Orion. New research now suggests The Hurlers were built as a primitive calendar which indicates the exact date of mid winter. Once a year at midnight on the winter solstice, they line up exactly with Orion's position in the night sky.
Three stone circles with diameters around 35m are grouped together on Bodmin Moor to make up the Hurlers, named from the legend of 'men being turned to stone for profaning the Lord's day but hurling the ball'
