The Château de Blâmont is a castle built at the end of the 13th century in the French commune of Blâmont, in the département of Meurthe-et-Moselle.
It underwent successive alterations and extensions in the 13th, 14th and 17th centuries which have made it one of the most beautiful medieval castle ruins in Lorraine, thanks to the preservation of five towers.
Despite heavy damage by American bombardment in 1944, the building has survived. Built around 1200, the castle was given new fortifications a century later. In the 16th century, a Renaissance-style building was constructed within the walls. The fortress suffered during the Thirty Years' War. During the 19th century, the medieval part was converted into a romantic castle, and part of the site became a weaving mill. In 1912, the castle became the property of a chocolatier, Fernand Burrus, who added two towers. Today, members of the Association Clef de Voûte maintain the site and organise events.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.
