The quarry near Lake Neusiedl in Sankt Margarethen, Austria, has transformed into a unique open-air stage for Richard Wagner's opera 'Der Fliegende Holländer'. The production involved nearly two years of preparation, with a focus on set design and rehearsals. The performance area is 950 square metres, with elements reaching 22 metres high, and the natural surroundings play a significant role in the show. Weather conditions pose challenges, affecting rehearsals and performances. The quarry, a UNESCO World Heritage Site, has been operational since Roman times and provides materials for Vienna's iconic buildings.
