The most famous of the Passion plays to survive into the 20th century is that performed at Oberammergau, in the Bavarian Alps. According to tradition, the play has been presented every 10 years since 1634, in fulfillment of a vow made after the village was spared an epidemic of plague (shifting to decennial years in 1700), except in 1870 during the Franco-Prussian War and World War II, when religious plays were banned. It remains an entirely local production, with villagers taking all the parts and singing in the chorus. Since 1930 roofed seats have protected the audience from the weather. The production runs from May through September. Some villagers and some Jewish organizations have protested anti-Semitic overtones in the 1860 text. Traditional Passion plays have also been revived in villages in the Austrian Tirol. In northern Spain, during Lent and Holy Week, a Catalan Passion play is performed by villagers; and in Tegelen, in the Netherlands, a modern play by the Dutch poet Jacques Scheurs is given every five years.
