St. Edmund's Church was built in 1883-84, and is home to the Norwegian congregation of the Church of England. Queen Maud used to visit this church, and there is a bust of her in the church, which otherwise is adorned with stained glass windows.
The church has modest size. While churches often dominate their surroundings and towers stretches over neighboring buildings, is this church modestly squeezed between larger buildings. It is said however that it came more into its own after some old buildings around it were demolished.
The church has - despite its small size - the shape of a cathedral. It was designed by architect Paul Due and Bernhard Steckmest and is in yellow and red brick in a simple, neo-Gothic style. The church was restored in 1990, and the tower was then replaced with a new one of roughly the same shape and size as the original.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.
