Perran Round is the best surviving example of a plen an gwary, a Cornish medieval amphitheatre. Indeed, it is often described as Britain’s earliest theatre.
Cornish language miracle plays were performed in these structures across much of Cornwall throughout the Middle Ages. It is widely believed that Perran Round was specially created as an open air theatre, although it is possible that it was an Iron Age or Romano-British enclosure adapted for use in medieval times.
