The Prinsen Castle

The Prinsenkasteel was the residence of the Lords of Grimbergen from the 14th century. Its ruins are located in the Prinsenbos, south of the center of the Belgian municipality of Grimbergen.

In the Prinsenbos, the Prinsenkasteel immediately attracts attention.
It was the residence of the Lords of Grimbergen and is named after Philip-Frans van Bergen, Prince of Grimbergen. The castle dates from the early 17th century; during World War II it was an ammunition depot that was set on fire by the retreating Germans in September 1944.
The castle's former moat now serves as a fishing pond.
In the heavy square pillars that still support the vault of one of the halls, the coat of arms of the family can still be clearly distinguished with inscription 1610.

After the castle on the Borgtberg burned down during the Grimbergen War (1141-1159), the Lords of Grimbergen built a new residence at the place called "Boksem", about 600 m south of the village centre and the Norbertine abbey. This probably did not happen until the end of the 13th or in the 14th century, as no deeds were signed at the castle in Grimbergen in the 13th century. This castle was also demolished down to its foundations after a siege in 1488 by Maximilian of Austria and in 1489 by Duke Albert of Saxony. Reconstruction began at the end of the 15th century, possibly on the old foundations. The map book of the abbey (1699) and the copper engraving by Sanderus (1727) show a walled castle on the north side preceded by a walled farmyard. (Inventory of Immovable Heritage)
