The benches, just outside St John’s village and overlooking the north coast, were smashed at the end of last week, in an attack branded as ‘disgraceful’ by parish Constable Graeme Butcher.
Mr Butcher says he is offering a reward for information that leads to prosecution of the vandals.
Anyone with information should contact the police on 612612 or Crimestoppers on 0800 555 111.
