Arbor Low,
Derbyshire is a prehistoric henge monument, that is, it consists of a
circle of stones set inside a circular ditch with a bank enclosing the
complete structure. It is unclear what henges were used for but
it seems likely that whatever went on there was designed to be seen
only by a few chosen people. The bank around the monument would have
made it impossible to see activities within the stone circle from
outside. Perhaps observers sat on the inner side of the bank, but it
would still have been available to only a restricted few.
