The earliest known records of Dagsnäs estate date back to the 15th century, when it was owned by Gumsehuvud family. The current main building was built in 1772-1782 by Per Tham. The current appearance originates from the restoration made according the plan of Helgo Zettervall in 1874. Over the years several Viking age runestones from the region have been moved to the castle grounds.
References: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.
