The earliest historical proof of existence of the Hervartov village is from the year 1340. The exact date when the wooden church was built is not known. According to the saved remains of the original Gothic altar, which was probably in place in the second half of the 15th century - the altars of St. Catherine, Virgin Mary and St. Barbara are from the years 1460-1480. This assumption is supported by the fact that the architecture and overall conception of the interior of Hervartov's wooden church, such as its stencilled geometric painting in the presbytery, may be associated to some extent with several churches on the Polish side of the Carpathian Mountains.
Saint Francis Church has a Gothic character as represented by its tall but narrow structure unusual for a wooden church. The floor is made of stones again unlike in most of wooden churches where it is usually made of wood.
Hervartov church is part of the UNESCO World Heritage Site of Wooden churches of the Slovak Carpathians.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.
