The history of Rimburg Castle cannot actually be described in a few lines. Its history dates back to around 1100. The so-called Bergfried or Belfried stood on original Roman masonry. However, nothing remained of the old stronghold and a new castle was built around 1200. Roman remains are still present in the current castle. The castle was located and controlled a large part of the busy trade route from Brabant to Cologne. The manor originally belonged to the Duchy of Limburg. In 1288 she came to the Duchy of Brabant. In 1278 the Duke of Brabant had already captured and destroyed the castle. A consequence of the behavior of robber baron Willem van Mulrepas (1253-1287). However, about twenty years later it was rebuilt. It now had 4 round towers and a second rectangular wing was built. A little later there was even a third wall with a wide ring of water in front of it. After 1300 the castle grew into one of the strongest castles in the area. Casemates were placed at the four corners of the ring wall and were connected to the castle by underground passages. The casemates had 4 floors with extremely thick walls. One of these casemates must certainly still exist. The strength of the castle and its casemates was proven in the October days of 1944 when the Americans had the greatest difficulty in taking the castle. Via underground passages there were connections not only to the casemates but also to bunkers in the Rimburgerbos on the other side of the canals. More than 100 people died during that time. In August 1543, Emperor Charles V marched with his army to Rimburg. After the capitulation, the outer works of the castle were completely destroyed. The castle was subsequently sold several times. In 1658 the new lord Von Boeymer had to invest enormously to restore the castle. It was also strengthened again. During the Eighty Years' War, the castle was occupied by a Spanish garrison for a long time. Later, a huge amount was invested in the castle to restore it to its former glory. In 1960, work was completed to repair the damage during the liberation. From April 23, 1949 to 00:00 on July 31, 1963, the castle was again within the Dutch borders. The Worm became the border river again and the castle was permanently located in Germany.
