The abbey of our Lady of Bonport was founded in 1189 by Richard the Lionheart, King of England and Duke of Normandy. According to legend, the King was in peril on the river Seine and made a vow that if he arrived safely (in French à Bonport) on the other bank of the river, he would found a monastery on that side. The abbey was built shortly afterwards with the help of local lords and was damaged and restored several times throughout history. Its closter and church were destroyed after Revolution. It is one of the few remaining cistercian abbeys in Normandy with monastic buildings of the Middle Ages including a magnificent 13th century vaulted refectory.
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.
