The Orthodox Church Museum, established in Kuopio in 1957, derives from the Collection of Ancient Objects founded at the Monastery of Valamo in 1911. Most of the exhibits, which consist mainly of icons, sacred objects and liturgical textiles, are from the monasteries and congregations of Karelia: a region in southeast Finland that was partially ceded to the Soviet Union in connection with the Second World War. Objects in the museum are mainly from the 18th and 19th centuries.
In addition to the permanent exhibitions, the museum offers yearly seasonal exhibitions. These theme-based exhibitions are aimed to introduce the variety of ecclesiastical art of eastern Christian Church. The virtual exhibition is built in accordance to the physical frames of the museum building: icons and sacred objects are displayed upstairs, liturgical textiles downstairs.
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.
