The Haelense Beek or Haelensche Beek has a length of eleven kilometers and is of great cultural-historical importance because of the castles that lie along it, such as the Baexem and Aldenghoor castle. The stone building of the Vogelmolen, a former watermill, is also next to the castle. At the start of the stage you will pass Castle Baexem and at the end you will pass Castle Aldenghoor. Baexem Castle was first mentioned in writing in 1244. The first inhabitants were descendants of the Van Baexem or De Baexem family. The oldest part of the current castle are the cellars. The current buildings are from 1676 and younger. The wings were added in the 18th century, giving the building a symmetrical appearance. The first mention of Aldenghoor Castle dates back to 1212 when there is mention of a fortified house Ghoor of the lords of Ghoor de Horne. When these gentlemen had a new castle built in nearby Neer, this was called Neyenghoor and in response to this the castle in Haelen was renamed Aldenghoor (new Ghoor and old Ghoor respectively).
