The Salpa Line is a massive line of defensive fortifications approximately 1200 km long that was built in 1940-41 and in 1944 in order to defend the Eastern border of Finland.
The Salpa Line Museum in Miehikkälä is a museum on military history established in 1987 displaying the history of fortification works of the Salpa Line. The permanent exhibition of the museum consists of the exhibition and multimedia shows at the museum cafeteria and of guided tours to the fortifications on the outdoor museum area.
Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
