On July 8, 2026, the Steinbruch (quarry) in St. Margarethen, Austria, will host an outdoor production of Giacomo Puccini’s opera "Tosca," featuring 271 elaborate costumes.
The production, announced by local cultural institutions, will combine Puccini’s iconic score with a set design that leverages the quarry’s stone walls. The 271 costumes are said to reflect the opulence of the 19th-century Roman setting of the opera.
The History and Significance of Open-Air Opera
Open-air opera performances have a long tradition in Europe. The Steinbruch in St. Margarethen has been repurposed as a cultural space. Its natural amphitheater shape and acoustics make it an ideal location for large-scale performances.
Costumes: A Central Element of the Production
The 271 costumes, described as “prachtvolle Kostüme” (magnificent costumes) in local media, are a focal point of the production. Each garment is designed to reflect the period and social status of the characters in Puccini’s opera, which follows the tragic love story of Tosca, a singer, and her lover, Cavaradossi. The costumes will be crafted by a team of designers.

Community Engagement and Accessibility
The event includes a public participation component, with a contest (Gewinnspiel) offering free tickets to attendees who submit creative entries inspired by the opera.
