The Sainte-Gaubuge priory was originally a hamlet, which is very well preserved. All the houses are located around the priory. The church building dates from the 13th, 15th and 18th century. The canons of St. Denis are at the origin of the most beautiful architecture sites. Rich carved decorations (13th and 15th century), the house of the prior has magnificent chimneys listed (15th century), and the vaults (13th century) are worth of seeing. Guided tours are available.
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.
