Floda church well known for its architecture and decorations. The original church was built in the 12th century, but the current brick church was built over it in 1886-1888. The rich mural paintings were made in 1480s by Albertus Pictor and are very well-preserved. The original colours are still visible due walls have never been whitewashed or overpainted as usually in old churches.
There is a Baroque chapel of field marshal Lars Kagg (1595-1661) in the church. It was designed by Erik Dahlbergh in 1667. In the sacristy is located a reliquary from the 15th century. The pulpit dates from 1662. There are also paintings Lars Kagg brought from Germany as a war booty, for example a Jean Boulanger's masterpiece made in 1618.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.
