A separate wooden building was constructed in what is now the Bibliothekshof  by Lodovico Ottavio Bumacini for the wedding of Leopold I and Margarita Teresa in 1666. It had a rectangular shape (64.6 x 26.6 m., 14.6 m. in height) with three galleries and probably seated about 1000 persons.

It had two arcaded levels of galleries and the acting area, as usual, spilt forward on to the floor of the house. As rebuilt thirty-five years later by Giovanni's son, Ludovico, it had three tiers of galleries on an awkward rectangular plan, but a splendid trompe-1' ceil ceiling which made it seem larger than it really was.
