In the Middle Ages, the Plays were presented on wagons that were pulled by craft guild members from one 'playing station' in York's streets to another. This was each Corpus Christi Day; it usually falls in June.
In 1951 a very practical decision was made to present the plays in one static space - the romantic ruins of St Mary's Abbey, in Museum Gardens. But Canon Purvis, responsible for providing a playing text for the production, also produced the script for a 'Wagon Play' focusing on one of the stories not featured in the 'main' production. In each of the subsequent productions at three-year intervals, a different story (such as The Flood, or Exodus) would be presented on a wagon by youngsters from the Archbishop Holgate Grammar School.
In the 1970s two scholarly attempts (in Leeds and Toronto) were made to reconstruct the York Cycle in its processional form. The University of Lancaster (especially Meg Twycross) continued these 'experiments' in York. In 1992, to accompany Mystery Play performances in the Theatre Royal, the Wakefield Play and the York Pageant of Herod and the Three Kings were performed on a wagon in the courtyard of Barley Hall (owned by York Archaeological Trust).
In 1994 Leeds-based historian Jane Oakshott worked with the Friends of York Mystery Plays, the Centre for Medieval Studies at the University of York and the York Early Music Festival to direct the first processional performance of York's Plays in modern times. This innovative production involved nine amateur drama groups on 10 July at five playing stations (Dean's Park, King's Square, the market place, St Sampson's Square and Parliament Street). It was a considerable success.
In 1998, Jane Oakshott returned to York to direct a second processional performance. She brought eleven plays to the streets, ambitiously re-creating some stunning theatrical sets and, for the first time since the the plays ended around 1570, involving the York Guilds in their own tradition.
By 2002 this initiative had blossomed and the Guilds themselves presented a cycle of ten plays at five playing stations under the direction of Mike Tyler. In 2008 Jane Oakshott was awarded an MBE for her pioneering revival of street performance of the English Mystery Plays.
The Guilds and other groups such as York Settlement Community Players, York Civic Trust, the University of York St John and local church groups have continued to 'bring forth' wagon plays in 2006, 2010 and 2014. This image shows actors from the Butchers' Guild hauling Christ up, having nailed him to the Cross. Their wagon is specially built. It is expected that the next wagon cycle will be in 2018.
Below right, the Guild of Builders approach the playing station near Clifford's Tower in 2010. Their Guild performs The Creation of the World to the Fifth Day.

There were two wagon plays complementing the Museum Gardens production in August 2012. The attached page shows photographs from those 2012 productions.
