The Château de Pierre-Percée ('pierced rock castle') in the commune of Pierre-Percée. The site in the early 12th century was in possession of Agnès, countess of Bar and widow of the count of Langenstein. She married Hermann II, Count of Salm and son of Hermann I, King of Germania (Eastern Francia). A well dug (~30 m) into the rock gives the village and the castle their name. The territory, which included the towns of Badonviller (which became the capital of the county) and Blâmont, became for several hundred years part of the hereditary property of the Counts of Salm. Around 1134, Hermann II went to war allied to the Duke of Lorraine against the Count of Bar and Stephan of Bar, the Bishop of Metz, himself a member of the Bar family. Hermann was killed on the battlefield outside the Château de Frouard. The castle at Pierre-Percée was besieged for a year and fell into the hands of the bishop of Metz with the death of Hermann's eldest son.
The castle was not besieged again until the Thirty Years' War (1618-1648) when, being deserted, it was destroyed by Franco-Swedish troops.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.
