Tips from the Community
At the intersection of Kanseliersdreef and Godendreef in the Mollendaalbos, you will find Den Dikken Eik on a small path named - how could it be otherwise - the Dikke Eikdreef. With a trunk circumference of 5.46m, Den Dikken Eik is the heaviest tree in the Meerdaalwoud. In 1995, a pencil-thin rod of wood was drilled into the core of the tree to count the annual rings: at that time, there were 320. Today, there are 351. Quite an age, therefore.

Strategically located picnic spot with - as the name of the avenue already reveals - a clear view of the straight avenue.

The most visible of Dzia's works at the station. Look for the others too. For those who don't know Dzia: some time ago an article appeared in OKV (Openbaar Kunstbezit Vlaanderen) with a photo of a work here at the station and the following description of Dzia: "Dzia is also passionate about animals. He mainly depicts wild animals. Foxes and birds seem to be recurring favorites. His unique style creates a mosaic of colors that follows the contours and shapes of the animal. In his more recent work, he adds tonal shading within each defined area, enhancing a sense of volume. His work tries to give animals a place back in an urban environment. The locations of his murals are carefully chosen and he positions his colorful animals in such a way that a playful interaction with the surroundings is created."

The Groenendaal station and its associated shelter were built in the typical "national" station style between 1893 and 1896, in this case a rather luxurious execution due to the abundant use of natural stone and great attention to detail. This can possibly be explained by the great attraction of Groenendaal to the Brussels bourgeoisie as an ideal starting point for a forest walk combined with a restaurant visit, but also by the figure of Leopold II, who was reportedly directly involved in the design and was a regular visitor to the Groenendaal racecourse (1889). The Groenendaal station, near the Zoniënwoud, is the only station building on the Brussels-Luxembourg line in Flemish territory. This railway line was built between 1847 and 1857 by the "Grande Compagnie du Luxembourg", which also had the management concession.

Some former bunkers of the KW line have been repurposed as overwintering spots for bats. And this applies to this one too. The municipality of Haacht was and still is one of the most active in managing these and other remnants of the war. For those who follow the KW line in detail: you will also find it on the map with all constructions, at https://www.regionalelandschappen.be/kw-linie There it is described as type P 41 second-line defense.
