Wyatville, it included a purpose-built Sculpture Gallery to house his collection. He took over several rooms in the house to contain the entire libraries he was purchasing at auction. The 6th Duke loved to entertain, and the early 19th century saw a rise in popularity of country-house parties. In addition to a sculpture gallery, the new north wing housed an orangery, a theatre, a Turkish bath, a dairy, a vast new kitchen and numerous servants rooms. In 1830 the Duke increased the guest accommodation by converting suites of rooms into individual guest bedrooms. People invited to stay at Chatsworth spent their days hunting, riding, reading and playing billiards. In the evening formal dinners would take place, followed by music, charades and billiards or conversation in the smoking room for the men. Women would return to their bedroom many times during the day to change their outfits. The guest bedrooms on the east front at Chatsworth are the most complete set from the period to survive with their original furnishings. There is much eastern influence in the decoration, including hand-painted Chinese wallpapers and fabrics typical of Regency taste, which developed in the reign of George IV (1762–1830). Those who stayed at Chatsworth included Queen Victoria and Charles Dickens. In October 1832, Princess Victoria (later Queen Victoria) and her mother, the Duchess of Kent, visited Chatsworth, where the Princess had her first formal adult dinner at the age of 13, in the new dining room. The 6th Duke had another chance to welcome Victoria in 1843, when the Queen and Prince Albert returned to enjoy an array of illumination in the gardens, in the conservatory and on the fountains, forming a scene of "unparalleled display and grandeur", according to one guest. The Duke spent 47 years transforming the house and gardens. A Latin inscription over the fireplace in the Painted Hall translates, "William Spencer, Duke of Devonshire, inherited this most beautiful house from his father in the year 1811, which had been begun in the year of English liberty 1688, and completed it in the year of his bereavement 1840." The year 1688 was that of the Glorious Revolution, supported by the Whig dynasties including the Cavendishes. The year 1840 brought the death of the Duke's beloved niece Blanche, who was married to his heir, the future 7th Duke. In 1844, the 6th Duke privately printed and published a book called Handbook
