The area in Sint-Pieters-Rode was in the Middle Ages strategically located near Louvain, which until the mid-14th century was the largest and most important city of the Duchy of Brabant.
In the 13th century the Horst family built a farm, which was fortitied as a moated castle in the the late 1300s by knight Pynnock. The castle was destroyed during the uprising of 1488-1489 against Maximilian of Austria. The castle was rebuilt but demolished again in 1500 and 1587, this time by the Beggars. The 15th century square keep still exists. In the 17th century, the castle was owned by Maria Anna Van den Tympel. She built a new chapel an decorated the ceiling of banqueting hall.
Today Horst Castle is open to the public.
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.
