Château de Liettres was probably built some years before 1479 by Sir Simon de Luxembourg, provost of the church of Saint-Omer. In that year it was burned by the progressing army of Maximilian I of Austria.
In 1542 Liettres Castle was again burned and partly destroyed by the troops of the Duke of Vendome. Shortly thereafter the castle was bought by Jean de Zomberghe after which it remained in the hands of his descendants.
Liettres Castle was built on an artificial plot of dry ground in the marshy valley of the La Laquette stream which also fed its moats. During the course of centuries it underwent several transformations. In 1720 the main building was rebuilt. It consists of several buildings forming a square with strong cylindrical towers. It has walls of 2.5 meters up to 5 meters thick in some towers.
At present the castle is privately owned and inhabited.
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.
