A plain-an-gwarry or playing place (Cornish: Plen an Gwari) is a Cornish Medieval amphitheatre. St Just in Penwith and St Piran's Round in St Agnes are two such examples. The St Just plain-an-gwarry is a large circular space, encircled by a 2 metre high wall of stone. There are 2 entries into the space.
The theatre area could be used for local gatherings, sports events, and production of plays. Cornwall culture had a type of play called miracle plays, written in the Cornish language, that would were meant to spread Christianity. To capture the attention of the audience, "the plays were often noisy, bawdy and entertaining."
The most important work of literature surviving from the Middle Cornish period is Ordinalia, a 9000-line religious verse drama which had probably reached its present form by 1400. The Ordinalia consists of three miracle plays, Origo Mundi, Passio Christi and Resurrexio Domini, meant to be performed on successive days. Such plays were performed in a plain-an-gwarry.
