The Zwinger was formally inaugurated in 1719, on the occasion of the electoral prince Frederick August’s marriage to the daughter of the Habsburg emperor, the Archduchess Maria Josepha. At the time, the outer shells of the buildings had already been erected and, with their pavilions and arcaded galleries, formed a striking backdrop to the event. It was not until the completion of their interiors in 1728, however, that they could serve their intended functions as exhibition galleries and library halls.
