The Svojanov Castle was built in 1224. During the reign of Ottokar II of Bohemia, it was used for protection of the trade route from Bohemia to Moravia. The first written mention of the settlement below the castle called Svojanov is from 1287. It was then owned by Záviš of Falkenstein, who had the small fortress extended into a big Gothic castle. The village of Starý Svojanov was founded in the 13th century and supposedly is the oldest part of today's municipality.
In 1421, Svojanov was besieged by Jan Žižka and between 1642 and 1645, the market town was occupied by the Swedish army. In December 1798, the Russian legions marched through Svojanov to fight against Napoleon.
The castle ruins are open to the public and often are used for cultural purposes.
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.
