Juliusza Słowackiego w Krakowie) is a 19th-century Eclectic theatre-opera house in the heart of Kraków, Poland, and a UNESCO World Heritage Site.

[2] The theatre was named after Polish poet Juliusz Słowacki in 1909 and in 1978 was inscribed alongside the Historic Centre of Kraków into the World Heritage Register.

The church was dismantled in May 1892 – an event which caused much controversy, notably the emotive declaration of Polish painter Jan Matejko, that he would never exhibit his paintings in Kraków again.

Inauguration took place with a program consisting of excerpts from Aleksander Fredro's Zemsta, Juliusz Słowacki's Balladyna and Adam Mickiewicz's Konfederaci Barscy.

The Theatre became the birthplace of the theatrical concept of the Young Poland movement and was closely related to the rediscovery of Romantic drama as well as the premiere productions of plays by Polish national playwright Stanisław Wyspiański.

The significance of the Polish Romantic tradition under the foreign occupation and especially Słowacki's legacy was reflected in the first festival of his plays organized there in 1909.

At the time, however, it was an avant-garde solution that challenged reigning canons.At the Theatre, the audiences could witness actors such as Kazimierz Kamiński, Ludwik Solski, Maksymilian Węgrzyn, Antonina Hoffman, Wanda Siemaszkowa, Stanisława Wysocka and Aleksander Zelwerowicz.

In 1980 the Słowacki Theatre staged the world premiere of Pope John Paul II Our God's Brother (Brat naszego boga), a production whose significance was above all political.
