Fleeing from the Normans and carrying with them the relics of their founder, St-Laumer, some Benedictine monks found shelter in Blois where they decided to build their abbey. the present church, today known as St. Nicolas, but whose real name is St. Laumer, was the former abbey-church.
From 1138 to 1186 these monks built the choir, the transept and the first row of columns of the abbey-church, completing it at the beginning of the next century. During the War of Religion the church was disfigured and the abbey itself destroyed by the Protestants. In the 17th and 18th centuries abbey was rebuilt, it was turned into a hospital at the time of the Revolution.
The speed with which the church was built and the sole addition of the apse chapel in the 14th century give a surprising unity to the whole. On entering the church, one could imagine that it was worked in the same stone by the same workman, for the same majestic and robust characteristics appear in all the different parts of the church. The elegant form of the choir, the crossbar, the majestic pillars of the transept-cross, the statues of people and masks which are to be found along the entire length of the building, the perspective inside the church, where the horizontal lines dominate the verticals; all this adds up to harmonious ensemble, which places the abbey-church of St. Laumer among the most remarkable examples of French medieval architecture.
However, two different periods of construction - about 20 years between them - have left the building with two different, and very marked, architectural styles. It is from the center of the church that the visitor will be able to notice these characteristics the most easily.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.
