The history of Olavinlinna Castle in Finland.

…

…Olavinlinna served as a prison in Finland. During the 1860's two fires broke out and caused major damage. The castle was then restored thoroughly from 1961-1975. Today Olavinlinna contains two museums, a restaurant, and festival halls. The museums are the castle museum and the orthodox museum. The castle museum has material found inside the castle as well as material dealing with the castle on display. The orthodox museum displays icons and other Russian Orthodox items.
