The manor of Vauville was originally built as a fortress in 1163 by Richard de Vauville who participated in the Conquest of England with William the Conqueror. The current château was built in the 1650s. It has been in the same family since 1890. The garden was created in the moat in 1947 by the parents of the present owners, who had a particular interest in exotic plants. Since 1980 the garden has grown from two to eight hectares. Reflecting pools where created, the banks restored, hedges to protect against the wind were integrated to give coherence to the garden. The current owners continue to collect unusual plants from all over the world. The on-going development and maintenance of such a garden only 300 yards from the sea with direct exposure to sand, wind, salt, and difficult weather, is a very challenging project.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.
