by the stucco decorations of Antonio Bossi. The white stucco works on a light gray background are composed of a large quantity of rocailles, mixed with images of real items, especially of military purpose. The lack of gold and colour allows the eye to rest between the splendours of the staircase and the Kaisersaal beyond. Five crystal chandeliers were used to light the room. Imperial Hall or Kaisersaal This hall opens to the east from the White Hall and is located in the center of the garden front. It was used to receive visiting dignitaries, including the Emperors-to-be on their voyage to Frankfurt and on the return trip to Vienna. It was created in 1749–51 at enormous cost. The walls of the Imperial Hall consist of stucco work marble in shades of red, white and yellow. The dome is painted in white colour, decorated with golden stucco work and also frescoes by Tiepolo, showing an idealized history of the diocese of Würzburg. One picture, Die Trauung Kaiser Barbarossas und der Beatrix von Burgund durch den Würzburger Fürstbischof 1156 shows the marriage of Emperor Frederick I Barbarossa and Countess Beatrix of Burgundy, consecrated by Gerold, Bishop of Würzburg. The opposite picture shows Frederick II appointing the Bishop of Würzburg Duke of Franconia. On top of the dome a painting shows the Brautfahrt: Apollo in the sun chariot leads the bride Beatrix surrounded by Venus, Ceres and Bacchus towards the Emperor Frederick II, who is accompanied by the Bishop of Würzburg. Giovanni's son Domenico created the supraportes: Emperor Justinian I publishes the Corpus Juris Civilis, Emperor Constantine the Great orders the execution of Gallus, Ambrose denies access to the church to Emperor Theodosius I. Bossi's figures show Poseidon and Juno as well as Flora and Apollo. Southern and Northern Imperial Apartments or Kaiserzimmer When all the doors are opened between these halls they create an enfilade stretching along the garden front extending a total of 150 meters. These rooms served as reception halls and as accommodation for important guests. The impact of both apartments is generated by a sequence of rooms of increasing degrees of decoration. The most decorated room of the Southern Apartment is the Spiegelsaal or Mirror Cabinet. Its walls consist entirely of glass panels, decorated on the back using either paintings, or drawings engraved into a gold ground and then underlaid with dark gloss paint. All the paintings and
