Finally in 1950, this opera house could open up its doors, after a war period when all opera and theatre stages in Gdansk were destroyed by the Red Army. Since then it has been well visited by a cultural interested crowd. Several different music and dance performances are held here every year.

It was built on a site of a Jesus college. It was a foundation, set up by clerics from Madrid's Royal Monastery (Monasterio de la Visitación), under the patronage of the princes Carlos María Isidro de Borbón and his wife, María de Asís de Braganza y Borbón. The monastery was built in neoclassical style, between 1826 and 1832. On the outside, the facade is made from black and red marble, featuring the shields of Spain and Portugal, Saint Charles Borromeo, Saint Jane of Chantal and Saint Francis of Assisi. Inside the church, built in the shape of a Latin cross, there is an interesting collection of religious paintings by the Court painter, Vicente López and his school (Valencia)

Dedicated to the Romantic poets — Keats, Shelley, and Byron — who each stayed in Rome and died tragically young, this charming period house contains a chain of rooms lined with rare books and relics, including Keats' last resting place. There's also a gift shop, an introductory film, and a spacious terrace.
