Clam castle was built in 1149 by Otto von Machland who owned all of Upper Austria. At that time it was a fortress consisting of two towers over 30 meters high. These two impressive buildings, one round and one rectangular, still exist in the very same shape today.
Soon after Otto von Machland died, the castle fell into the hands of robber barons. They were feared by the people of Upper Austria and excommunicated by the church. During the middle ages the ownership and construction of the castle changed several times until in 1454 the forefathers of the counts of Clam arrived
During the 30 year-war the Clam family had their own private army to defend the castle. In these times of turmoil and revolts Clam village also suffered a lot and was burned down several times. Clam was besieged many times but no hostile troops ever managed to capture the castle. However, in the mid 17th century when the war was over, the castle was in a very bad condition.
Under the regency of Johann Gottfried of Clam it was possible to renovate the entire castle. He started to transform the functional fortress into a comfortable castle as we see it today. He also built a church, a hospital and water pipes for the citizens of the village.
In the 18th century the wings housing the administration, the coaches and the horse stables were built. Today these wings form the outer yard.
Fortunately Clam castle also survived both world wars unharmed. Only the nuclear shelter, built in one of the castle’s cellars is a reminder of the 20th century.
Besides the Castle the estate includes several farmhouses, a riding school, a hydropower plant, farmland and forests.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.
