The Institut et Musée Voltaire is a museum in Geneva dedicated to the life and works of Voltaire. The museum is housed in Les Délices, which was Voltaire's home from 1755 until 1760.
The property was bought by the city of Geneva in 1929, and the museum opened in 1952, founded by Theodore Besterman.
It contains about 25,000 volumes on Voltaire and the 18th century as well as a collection of paintings and prints from the period, many depicting Voltaire, his relatives and acquaintances.
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.
