A story of love, jealousy, violence and intrigue meets breathtaking sounds: with Giacomo Puccini's Melodramma Tosca, one of the world's most popular operas returns to the St. Margarethen quarry, Europe's most beautiful open-air stage, in 2026. In Rome around 1800, the singer Floria Tosca and the painter Mario Cavaradossi fall madly in love, but the unscrupulous police chief Scarpia has his sights set on their happiness and does everything he can to manipulate Tosca in order to win her over. When Cavaradossi offers refuge to the wanted political prisoner Angelotti, Scarpia exploits his power and gives Tosca a choice: either she swears her eternal love for him or he will see to the end of Cavaradossi's life. Will Tosca and her lover be able to overcome the shadows of fate?

Giacomo Puccini provides a musical rollercoaster of emotions - from Tosca's poignant “Vissi d'arte” to Cavaradossi's powerful “Recondita armonia” and Scarpia's dark aria “Ha più forte sapore”. A firework display of emotions with gripping melodies that find the perfect echo in the rocky landscape of the St. Margarethen quarry.
