The Longstone (pictured above) is the only megalithic monument on the Island, and excavations believe that it dates from the Neolithic period. The Longstone consists of two pieces of local greensand sandstone. The larger is 13 feet high and the smaller lies next to it. The National Trust takes care of the stones and surrounding land, and it is open to the public. The author Coxe states that Druids used to sacrifice a white bull here. There was also a ‘logan’ (rocking stone), which moved with the wind, but could not be moved by the hand of a person with a ‘guilty conscience’. Even today, Pagans are drawn to this site each festival and many hand-fastings and rites of passage are celebrated here.
