    Features and characters of the individual
This gigantic common horse chestnut, as wide as it is high, sits at the top of the hill in Leopold Park. Stocky and powerful, almost intimidating, the tree is the guardian of the small entrance to the park. It is impossible not to notice it, not to slow down. Its presence is so strong, its crown is so dense. Its heavy branches, which cross the path, command the visitor’s respect. A little more and you’d have a hard time getting by. They are sprawling. They control the space, cross paths and fences, and in several places take root in the ground. They seem strangely alive. They give the tree a monstrous appearance. It is called "Le Poulpe". The kind of specimen found in Greek mythology: which Ulysses could have found on his Odyssey.
