St Athernase Church is a Romanesque church located in Leuchars. The chancel and half-round apse date from the 12th century with the exterior featuring blind arcades with typical Norman arches. The church was granted by Ness son of William, Lord of Leuchars, to the canons of St Andrews in 1185. Around 1700 a belfry was added, and in 1858 restoration was carried out to the nave.
The church is open to the public in summer, at other times by arrangement. Relics preserved inside include part of a 9th-century cross-slab found near the village (closely comparable to the large collection at St Andrews Cathedral), and three elaborate 16th century memorial stones of the Bruces of Earlshall, the local lairds. One of the latter shows a full length figure of a woman, naive in execution, but valuable in documenting contemporary dress.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.
