Saint Panteleimon Monastery was built in 1843 and became monastery in 1987. According to inhabitants of Thassos, someone wanted to build it in favor of Saint Panteleimon. The workers started the building at a location, but the next day when they wanted to continue with the construction, the part they had built was found destroyed and their tools were missing. The same happened on the following days. One day they saw footprints on the ground and followed them until they found their tools nearby a natural spring. Finally, they built the monastery at that spot.
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.
