Amphitheater

The amphitheater was inspired by the theater in Herculaneum and features a semicircular auditorium with arcades. It is adorned with a row of stone sculptures depicting 16 playwrights, including Aeschylus, Euripides, Sophocles, Aristophanes, Menander, Plautus, Terentius, Seneca, Shakespeare, Calderon, Racine, Molière, Metastas, Lessing, Niemcewicz, and Trembecki. The stage, situated on an artificial island, is surrounded by artificial ruins modeled after the Roman Forum and characterized by a sentimental style popular until the late 18th century. Behind the stage, there is a one-story pavilion with actors' dressing rooms. The orchestra sits between the stage and a canal, which was also sometimes used during performances. The stage is flanked by mythological sculptures.

After Łazienki became the property of Tsar Alexander I in 1817, the amphitheater fell into disrepair and no plays were staged there for a number of years. When Ludwik Osiński took ownership of the property in 1822, performances resumed, despite the lack of comfort. In 1930, around 900 people attended a performance of "White Lady." In 1916, the amphitheater was owned by the city and was renovated in 1926, during which the original 18th century sculptures were replaced with exact copies.

During World War II, most buildings in Łazienki, including the amphitheater, were spared destruction. German plays were staged there several times during the occupation. In 2015, the amphitheater underwent renovations as part of a larger project to renovate Łazienki. The auditorium was decorated with new sculptures and the stage and wardrobe areas were modernized.
