Juval Castle (Italian Castel Juval) is located at the entrance of the Schnalstal valley. It derives its name from the Latin name of the mountain, Mons Jovis (mountain of Jupiter).
The oldest account of the castle dates to 1278, when it was owned by Hugo of Montalban. It was probably constructed about thirty years before the first account referencing it. In 1368, it was acquired by the lords of Starkenberg, and in 1540, it passed to Sinkmoser. The period from its construction to the mid 1500s was the castle's heyday.
After several more changes of ownership, in 1813, it was sold to a local farmer, Josef Blaas. The castle fell into disrepair, until in 1913 William Rowland carefully restored it.
Since 1983, it is the summer residence (July and August) of famous mountaineer Reinhold Messner, who has partially converted it into a museum displaying works of Tibetan art and a collection of masks from five continents. A later restoration of the castle was presided over by Vinschgau architect Karl Spitaler. It is one of the venues of the Messner Mountain Museum. The museum is closed in the summer months, when Messner resides in the castle.
Around the castle there is a path open to the public along which there are informational signs relating to the botanical features on the grounds. For private individuals, the castle is accessible only on foot with an hour-long walk or by using a special bus service.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.
