Château de Larressingle was built in the second half of the 13th century. The second and third floors were added by Arnaud Orthon de Lomagne, Bishop of Condom, between 1285 and 1305. Windows were added at various times in the 15th and 16th centuries, particularly between 1521 and 1545 when extra works were carried out for Monseigneur de Grossolles, including the construction of a hexagonal tower.
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.
