Perran Round (also known as St Piran's Round) is an amphitheatre in the hamlet of Rose, midway between the villages of Goonhavern and Perranporth, Cornwall, UK. It is described as the best surviving example of a plen-an-gwary, a medieval amphitheatre used for performing the Ordinalia, or Cornish miracle plays,[1] and Cornish wrestling tournaments.[2]
