Drottningholms Slottsteater was built in 1766 at the request of Queen Lovisa Ulrika. The theatre is constructed of simple materials and the auditorium is playfully decorated using paint, stucco, and papier mâché. The wooden stage machinery is operated by hand. It includes wind, thunder and cloud machines, as well as traps and moving waves. About 30 stage sets have been preserved, all decorated with themes from 18th century repertoire.
