Frauenalb Monastery was founded in the late 12th century. It accepted as members only daughters of noble families. The accidental fire destroyed the monastery in 1508 and only abbey church built in 1404-1406 survived. The rebuilt monastery was looted again in 1525 during Peasants War.
Shortly after 1600 the last woman left the monastery. Today a foundation takes care of the preservation of the remarkable ruin.
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.
