The outdoor theatre in the village of Einsiedeln, Canton of Schwyz, will raise the curtain for the 17th time this summer – 100 years after the very first performance. The world theatre is inspired by a play written by the Spanish philosopher Caldéron. Since 2000, this play has been revisited to produce performances that don’t just involve Caldéron, but also current issues. The village has traditionally been involved both backstage and on stage, and the anniversary stamp pays tribute to this huge collective effort.
