Bor Castle was built in the mid-13th century. Švamberk family owned it until 1650. originally a medieval moated castle, it was altered in an extensive late Gothic reconstruction and later in the 18th century to the current appearance. It has been a popular tourist destination since opening to visitors in 2003. Tour begins on the ground floor, next to the ticket office, and includes the diamond-vaulted Švamberk Hall with a display of period costumes and weapons, St Lawrence Chapel, chateau picture gallery, rooms, as well as a climb up 117 steps to a lookout tower.
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.
