thank you Graham for the photos
The Hippodrome of Groenendael was built at the end of the 19th century at the request of King Leopold II. The race track was situated in the gorgeous forest de Soignes and once was one of the most beautiful and biggest tracks in Europe.
I have written about the Forêt de Soignes/Zoniënwoud before. It is located on the grounds of the towns Hoeilaart, Groenendaal, Uccle, Auderghem, La Hulpe, Waterloo, Tervuren...and the perfect outing for a green excursion close to the Brussels.
The Racetrack deteriorated and was abandoned, the main building has been demolished and what you see above, the Royal Lodge, is all that is left now. It seems that restoration will soon be on the way.
