In 1909, Paul Walther-Schäffer, the kapellmeister of the Municipal Theatre in Gdańsk, went for a walk to the wooded hills surrounding Sopot. Captivated by the beauty of the place, he decided to create a venue for cultural events in this stunning landscape. That same year, construction was begun of an amphitheatre in the forest, which was one of many new construction projects in Sopot (called Zoppot at that time) that led to the city eventually gaining the status of a luxury resort. Operas, plays and concerts were staged at the Zopotter Waldfestspiel, and it became famous for its Wagner Festivals.
In June 1945, after Sopot had become a Polish city, large events such as Polish Soldier’s Day and the Sea Festival were held here. The Sopot amphitheatre became a venue for popular festivals and musical events. In 1961, the famous pianist and composer Władysław Szpilman, who was also the director of the Popular Music Section of Polish National Radio at that time, proposed the idea of organising a festival of songs from all over the world in Sopot. And so, from 1964 onwards, the Forest Opera regularly hosted the Sopot International Song Festival, one of the most popular music events in the country.
Due to its increased popularity, the Forest Opera stage has been extended many times, and its most characteristic element – a roof made of light fabric covering an area of 0.4ha – was stretched over the open-air auditorium in 1963. This complex and modern structure was designed by the architect Janusz Kowalski.
