The Château de Trévarez is a stately home commissioned by James Kerjégu, Chairman of the General Council of Finistère, and built at the end of the 19th century by the French architect Walter-André Destailleur.
Trévarez is one of the most recent châteaux built in France. Construction was completed around the beginning of the twentieth century. In 1941, the château was taken over by the German occupying forces. The castle was bombed on 30 July 1944 by the Royal Air Force.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.
