[1] The southernmost Priddy Circle falls on adjoining land to a house and stables that are owned by retired businessman Roger Penny.

The four circles each consist of a flat circular area surrounded by a bank and external ditch enclosure with more than one entrance.

[1] Excavations carried out between 1956 and 1959 by members of the University of Bristol Spelæological Society showed that the banks had stone cores with post and stake holes on either side.

[10] The owner of the southernmost ring, Roger Penny, was fined £10,000 and ordered to restore the earthwork at a cost of £38,000 following the damage caused by contractors he had hired.

[3] The workers also cleared gorse and bracken between April and October 2011, bringing rubble into the field to help rebuild a wall and moving a gate.

Penny was aware the ring was a scheduled monument and told the contractors not to touch it, but because part of the site is not visible to the naked eye "serious damage" was caused.

[3] They are probably Neolithic ritual or ceremonial monuments similar to a henge but this interpretation is somewhat speculative due to the presence of external rather than internal ditches,[1] a feature which makes them unique in Britain.
