The Hofburg Palace is the former principal imperial palace of the Habsburg dynasty. Located in the center of Vienna, it was built in the 13th century and expanded several times. Empress Maria Theresa had a 17th-century opera house converted into the dance and concert halls now known as the Redoutensäle, forming the Redoute Wing. This 1763 oil painting by Martin van Meytens depicts the hall on the occasion of the wedding supper of Princess Isabella of Parma and Joseph II, Holy Roman Emperor, who were married on 5 October 1760.Painting credit: Martin van Meytens
