Moorsel was owned by the chapter of Dendermonde, probably from 868 on. One of the largest landowners in the region was the Abbey of Affligem, who possessed the church and the parish of Moorsel. Abbot Karl de Croy, Bishop of Tournai, built a water castle at Moorsel in 1546. The renaissance castle is still preserved in its original condition. The castle is constructed was intended as a summer residence for the Karl de Croy.
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.
