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:
First record of Kastelholma (or Kastelholm) castle is from the year 1388 in the contract of Queen Margaret I of Denmark, where a large portion of the inheritance of Bo Jonsson Grip was given to the queen. The heyday of the castle was in the 15th and 16th centuries when it was administrated by Danish and Swedish kings and stewards of the realms. Kastelhoma was expanded and enhanced several times.
In the end of 16th century castle was owned by the previous queen Catherine Jagellon (Stenbock), an enemy of the King of Sweden Eric XIV. King Eric conquered Kastelholma in 1599 and all defending officers were taken to Turku and executed. The castle was damaged under the siege and it took 30 years to renovate it.
In 1634 Åland was joined with the County of Åbo and Björneborg and Kastelholma lost its administrative status.
