construction cost came to over 1.5 million guilders, at a time when a day labourer could expect a weekly wage of one guilder. 19th and early 20th centuries The episcopal principality of Würzburg was abolished with secularization in 1802/03. An eight-year interregnum by Grand Duke Ferdinand of Tuscany (reigned 1806–1814) followed, during which he had several rooms of the south block, the so-called Toskanaräume (Tuscany Rooms), decorated in Empire style. Emperor Napoleon Bonaparte slept in the Residence when he stopped in Würzburg three times between 1806 and 1813. On 2 October 1806 he signed the declaration of war against Prussia here. A Neoclassical double bed and bedside tables were installed in the sleeping room of the northern Imperial Apartments for him and his wife Marie Louise in 1812. In 1814, Würzburg became part of the Kingdom of Bavaria. The wrought-iron gates across the Cour d'honneur, which had effectively separated this inner area from the large Residence Square, were demolished in 1821. In their place today is the Frankoniabrunnen (fountain) created by Ferdinand von Miller the Younger. This was unveiled in 1894 as a tribute by the city of Würzburg and the whole of Franconia to Prince Regent Luitpold, who was born in 1821 in the Würzburg Residence itself. Queen Victoria and Prince Albert stayed at the Residence on their way to Schloss Rosenau, Coburg, in August 1845. In 1921, the Residence was opened to the public. Destruction in World War II As a result of a devastating air raid on 16 March 1945, the residence was almost completely burnt out and only the central building with the Vestibule, Garden Hall, Staircase, White Hall and Imperial Hall survived the inferno, their roofs destroyed. From the attic the fire ate down through wooden ceilings and floors, and all the furnishings and wall panelling which had not been stored elsewhere were devoured by the flames. Much of the furnishing and large sections of the wall panelling of the period rooms had been removed in time and thus escaped destruction. Neumann's stone vaults withstood the collapse of the burning attic. However, because the roofs had gone, further damage was incurred in the ensuing period due to dampness. In the Court Chapel, for example, most of the ceiling frescoes by Byss succumbed to the subsequent consequences of the fire, in spite of the intact vault, and had to be laboriously reconstructed.
