Originally, in the 16th century, the site of the Manor House and gardens was used for royal farm buildings and Karlslund was mainly concerned with agriculture. The present Karlslund Manor House was built between 1804 and 1809 by Christian Günther. In 1819 a later owner, Carl Anckarsvärd, had the manor house rebuilt and altered to the appearance we know today. The architect behind this work was the famous Carl Christopher Gjörwell, who also furnished the upper storey of the manor house and laid out the beautiful park. Gjörwell also had the Stora Salongen (Grand Saloon) decorated with rare French panorama wallpapers. These show the most important ports of France and were hand-printed c. 1800. They are among the oldest rolled wallpapers extant in Sweden.
There are several cultural history displays and museums at Karlslund like the Statare Museum, power station (1897) and old mill. Today Karlslund Manor House is used as a restaurant and conference centre. Here one can book Sunday lunches, Christmas dinners, and so on. In the summer there is also a pleasant café on the terrace.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.
