To pad-out Rhiannon’s post
“A number of circles used formerly to be called “Law Stones,” probably because law courts were accustomed to be held near them.
The suggestion receives some support from the case of the Standingstones of Rayne, a circle at which, in 1349, a court was held to settle a dispute between the Bishop of Aberdeen and William of St Michael concerning the ownership of certain lands in the neighbourhood”.
