The evil wizard Rothbart casts a spell on the beautiful Odette, turning her into a swan – and only true love can break the spell. Hope arrives in the form of prince Siegfried, who swears never to betray her – the next day however he chooses the fiery Odile as his bride. At the end though it is the evil wizard who is defeated, when Siegfried gives his life for Odette so that they can be together eternally at least in death and save other girls who have been turned into swans. This tale of the great power of love was given musical accompaniment in the romantic melodies of P.I. Tchaikovsky: on a moonlit night an enchanted prince dances with the beautiful Odette, at the ball a Spanish dance, a tarantella, a csardas and a mazurka can be heard. The magnificent scenes are alternated by tender dances of love and sorrow. Probably the most romantic of Tchaikovsky's works, which is ever popular not only amongst visitors to Křižík's fountain, this has been brought into this unique environment by the choreographer and playwright Miloslav Janíček, and is performed by the Prague Theatre Ballet, directed by Jiří Pokorný. The production is enhanced by the film projection into the wall of water of the fountain.
