Osborne House is a former royal residence in East Cowes, Isle of Wight. The house was built between 1845 and 1851 for Queen Victoria and Prince Albert as a summer home and rural retreat. Albert designed the house himself, in the style of an Italian Renaissance palazzo. The builder was Thomas Cubitt, the London architect and builder whose company built the main facade of Buckingham Palace for the royal couple in 1847. An earlier smaller house on the site was demolished to make way for a new and far larger house, though the original entrance portico survives as the main gateway to the walled garden.
Queen Victoria died at Osborne House on 22 January 1901. Following her death, King Edward VII, who had never liked Osborne, presented the house to the state on the day of his coronation, with the royal pavilion being retained as a private museum to Victoria. From 1903 to 1921, part of the estate around the stables was used as a junior officer training college for the Royal Navy, known as the Royal Naval College, Osborne. Another section of the house was used as a convalescent home for officers. In 1933, many of the temporary buildings at Osborne were demolished. In 1954, Queen Elizabeth II gave permission for the first floor rooms (the private apartments) in the royal pavilion to be opened to the public. In 1986, English Heritage assumed management of Osborne House. In 1989, the second floor of the house was also opened to the public.
References:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
