La Chartreuse de la Verne, Carthusian monastery in Collobrieres, was built in 1174, however in 1264 and 1271 it was burned down. It wasn't until the sixteenth century that the present chapel and the great south gate were built.
The current Chartreuse is a lovely and imposing set of buildings, completely isolated in a hilly forest of pine, oak and chestnut, overlooking the artificial lake, Lac de la Verne.
The drive up to the monastery is a beautiful scenic trip. A community of nuns still lives in the building, making ceramics and other crafts for sale at their shop.
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.
