On the peak of a steep mountain situated on the right bank of the San river, the ruins of Sobień castle from the second half of the 14th century can be seen. The castle was owned by the wealthy chivalry house of Kmita. Then the Kmita family moved their abode to Lesko, where Piotr Kmita erected a castle in the16 th century, which was subsequently extended by the Stadnicki family. The castle is open to visitors.
An Italian park was established already in the 16th century and continued through the 17th century. In the 18th century the park was planted with lime tree alleys. They are listed in the castle records from that century. In the first half of the 19th century the Krasicki family established a landscape park around the castle.
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.
