Plen-an-gwary

A plen-an-gwarry or plain-an-gwary, is a "playing-place" or round, a medieval amphitheatre found in Cornwall. A circular outdoor space used for plays, sports, and public events, the plen-an-gwary was a Cornish variant of a construction style found across Great Britain. Formerly common across Cornwall, only two survive nearly complete today: the Plain in St Just in Penwith and Saint Piran's Round near Perranporth.
