Aizpute castle was built in the 13th and 14th centuries by the Livonian Order. This was regular planned castella type Order’s Castle with corner tower and wooden buildings in the yard. In the 15th century outside at the ring-wall was built the eastern block. After the Livonian War (1558-1583) castle was not suitable for habitation and in written documents from 1555 it is mentioned as a grain storehouse. At the time from end of the 16th till beginning of the 17th century castle was renovated and there still remain the rich parget with the splendid decorative design in the graffiti artistry above the gates that was shaped in that time.
In fights of the Swedish-Polish War (1600-1629) the castle was ravaged again, but in 1665 there were done the renovation works and the garrisons and gun-crews of Jacob the Duke of Courland were deployed there. After the death of Duke Jacob in 1682 castle became the property of Michael Fredrick Nolde. After rebuilding the castle lost its medieval shape of fortress and inside the ring-wall the new living block was added. Gradually the castle lost its adhibition as a dwelling and was inhabited just partly. For that time the culture level in the yard has grown up for 1.5 metres. In the beginning of the 19th century the eastern block and the south-eastern tower got their present flat vaulting and new partition walls. For the beginning of the 20th century the castle of Aizpute was unsuitable for inhabiting and for present day it has partly gone to rack and ruins.
In the beginning of the 19th century, when some parts became unsuitable for inhabiting, the lord of the manor lived in the new manor-house that was built near at the pond in the 2nd half of the 18th century. Later at the pond were built the water mill and the spirit distillery, but at the new manor-house were built the household buildings. Aizpute Evangelic-Lutheran Church and the former castle13-manor complex of buildings creates the unified group of towns-planning architectural objects that also includes the pond and water mill with the dam on the Tebra River.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.
