The Bibiena Theatre is unique in its kind. Its dimensions are not impressive: almost seventeen meters wide, and more than twenty-five meters in length. Its function is ambiguous, as is its aesthetic quality: surely a place for performances, but with a fixed scene and lacking a proscenium. The style of the building is anti-classical, so much that the facade and the hall named after Empress Maria Theresa, completed in the same years, are very different from the interior. The style is more Late Baroque than Rococo, a style that is indeed able to bring together and create harmony between architectural elements from different periods.
