The Swabian Castle in Oria is a wonderful construction built between 1225 and 1233 at the behest of Holy Roman Emperor Frederick II. Over the centuries, it has been inhabited by princes, knights and noblemen. It has a triangular plan and is characterised by three towers called Quadrata (Square), Del cavaliere (of the knight) and Del Salto (Jump): the first one was built during the time of Frederick II, while the other two under the Angevin domination.
According to a local tradition, the foggy atmosphere which shrouds the castle is not just a natural phenomenon, but it recalls something which happened during the construction of the castle, known as Oria Fumosa, foggy Oria. A must-see is the castle at sunset, with an amazing picture-postcard view, which can be admired from any place in the town.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.
