Ringkøbing Church was built in the early 15th century, and its tower, which is wider on top than on the bottom, was erected ca. 1550. The church houses two organs: the oldest in the west pulpit was built by Demant & Son in 1861 with a baroque facade from 1633. The other from 1974 is by Frobenius & Sons. As the result of a restoration in 1995-1996, the church has a number of modern features, including an altarpiece by Arne Haugen Sørensenand a glass baptismal font.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.
