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:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
