In 1184 Baldwin V, Count of Hainaut, built the first castle on the current site in Écaussinnes. The lords of Écaussinnes and their heirs the de Lalaings altered the original structure several times over the centuries.
In 1450 Marie de Lalaing married Jean II de Croÿ, descendant of the Counts (later Princes) of Chimay. By a quirk of inheritance, the castle later became the property of the Lalaing family again. They sold it in 1642 to the van der Burcht family.
In the 18th century the interior was redecorated with Rococo elements in the first floor of the Gothic hall.
References:The Pilgrimage Church of Wies (Wieskirche) is an oval rococo church, designed in the late 1740s by Dominikus Zimmermann. It is located in the foothills of the Alps in the municipality of Steingaden.
The sanctuary of Wies is a pilgrimage church extraordinarily well-preserved in the beautiful setting of an Alpine valley, and is a perfect masterpiece of Rococo art and creative genius, as well as an exceptional testimony to a civilization that has disappeared.
The hamlet of Wies, in 1738, is said to have been the setting of a miracle in which tears were seen on a simple wooden figure of Christ mounted on a column that was no longer venerated by the Premonstratensian monks of the Abbey. A wooden chapel constructed in the fields housed the miraculous statue for some time. However, pilgrims from Germany, Austria, Bohemia, and even Italy became so numerous that the Abbot of the Premonstratensians of Steingaden decided to construct a splendid sanctuary.
