Relatively little survives of the 18th century interiors, since Ulriksdal served as a veterans' hospital from 1822 to 1849. The hospital was established by King Charles XIV John for veterans of the Russo-Swedish War of 1808–1809. The palace was therefore almost empty when it was acquired in 1856 by Prince Charles, later King Charles XV. During the reign of Charles XV (r. 1859–1872), the palace was used as his preferred summer residence. With the aid of architect Fredrik Wilhelm Scholander and through extensive purchases of antiques, Prince Charles was able to design and furnish the palace at his own taste. Many of these furnishings are still on display. During the reign of King Oscar II (1872–1907), it was often used by Queen Sophia as her personal summer residence: it also served as her residence as a widow until her death in 1913.
