Aywiers Abbey was founded in 1215 by Cistercian monks. It prospered and grew thanks to donations up to 2000 hectares. During the the French Revolution the abbey will be sold and the new owner demolished it partly. Today the seven-hectare garden is surrounded by ancient walls, containing superb hundred-year-old tree specimens, shrubs and rare plants, a pond and springs as well as a garden of aromatic and medicinal plant.
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.
