.. the Banbury Stone [is] also known as the elephant stone because of its shape when viewed from one side.. [it] has been described as a sacrificial stone for Druids or as a Roman altar, but in reality is a natural outcrop. Locals believed that to kiss the stone on Good Friday would bring bad luck.. [The Stone is] situated inside the hillfort, the outstanding feature of the hilltop.
