The wooden church of the Archangel Michael in Debno is first mentioned in 1335. The present building, the second on the site, dates from the late 15th century. This church has a unique example of medieval decorations. The ceiling and the interior walls are painted using stencils from the 15th and 16th centuries. The decoration contains more than 77 motifs: architectural recalling Gothic forms, animal, human and religious.
The church is part of the UNESCO World Heritage Site of Wooden Churches of Southern Lesser Poland and Subcarpathia. The wooden churches of southern Little Poland represent outstanding examples of the different aspects of medieval church-building traditions in Roman Catholic culture.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.
