Popular around Watermael-Boitsfort - Bosvoorde
The Groenendaal racecourse was built in 1888-1889 on the initiative of Leopold II in the middle of the Sonian Forest, next to the road to Waterloo, and in 1892, as part of easy access, it received its own railway connection to Groenendaal station. To realize this racecourse, approximately 100 hectares of forest were cleared at the end of the 19th century. King Leopold II had his own box there, located between two metal grandstands for the public. After the First World War, this area was used for the dismantling of weapons and ammunition left behind in the Westhoek. German prisoners of war had to clear mines under the supervision of the Belgian army. During a fire and the subsequent explosions of ammunition on May 6, 1919, the hippodrome's grandstands and buildings were heavily damaged. After another explosion in November, the ammunition depot was completely dismantled in 1920. Two years later, the racecourse was restored and the grandstands were rebuilt. The royal box for Albert I was not rebuilt until 1924. Its appearance was completely different from the pre-war grandstand. When the current appearance came about is not entirely clear, although the current box is attributed to Albert I in the literature, see also monogram.

A monumental stone circle resembling a miniature version of Stonehenge. Located in a clearing in the woods near Duboislaan, this monument consists of eleven menhirs arranged in a circle around a large dolmen. Although it resembles an ancient megalithic monument, it is actually a memorial dating from 1920 for the forest rangers who died during the First World War. The stones are made of Wéris puddingstone, the same rock used in the prehistoric megaliths of that region. The monument was designed by artist Richard Viandier, who drew inspiration from Celtic burial rituals. This place symbolizes the forest rangers' connection to nature and therefore also has spiritual significance, similar to ancient Druid symbolism. The monument is a peaceful spot in the heart of the forest and also attracts visitors interested in history, nature, and mysticism.
