In 1648, King Philip IV of Spain gave the city of Halle and the Hallerbos to the Duke of Arenberg as collateral for a loan. When the king was unable to repay his debt in time, the duke acquired two thirds of the forest in 1655, which together amounted to 900 acres (i.e. approximately 1,125 ha). The Sint-Waltrudis chapter of Bergen remained the owner of one third. After a period of joint management, difficulties arose between the two owners. In order to put an end to the endless quarrels, they decided to withdraw from joint ownership, and to that end they had the forest measured in 1779. They placed 24 pyramid-shaped "meerstenen" or boundary posts with the inscription SW ("of Sint-Waltrudis") on one side and AR ("for Arenberg") on the other. Nineteen of these still stand on the original dividing line in the forest. Source: Wikipedia.

The ‘Hallerbos’, also known as the blue forest, is one of the 3 extensive forest areas in the Brussels capital area. It is an ancient forest with a mix of young and older trees. The giant Sequoia trees are pretty impressive as well as the beautiful purple carpet of bluebells, which bloom around mid-April. Crossing the forests on a mix of gravel and singletrack dirt roads make up for a visit well worth it!

The Hallerbos (French: Bois de Hal) is a forest with an area of 552 ha southeast of Halle (511 ha on Hals territory). The forest is largely owned by the Flemish Region and a small part of the Walloon Region and private property. The Hallerbos forms a quiet recreational area, which is highly appreciated by the population of the surrounding highly urbanized zones. It is very accessible thanks to the many paths, and three walking routes have been mapped out for an introduction. The forest is part of the Flemish Ecological Network, has been a Flemish nature reserve since 2021 [1] and is European protected as Natura 2000 area 'Hallerbos and nearby forest complexes with source areas and heathland' (BE2400009) (together with other subareas such as the Mark valley, Zuun valley with domain of Gaasbeek, De Wolfsputten, Kesterbeek valley, Kesterheide, the forest reserve Terrijst, Lembeekbos, Zevenbrons, Gasthuisbos, Begijnenbos).

Animals and plants The Wrangroot is related to the Christmas rose, has beautiful green flowers and blooms at the end of January.
