Lion's Mound in Braine-l'Alleud

You're standing at the foot of the Lion's Mound, the Butte du Lion, right in the middle of the Waterloo battlefield. Look up for a moment. That neat, perfect cone isn't a natural hill. It was built from around three hundred thousand cubic metres of earth, and that earth was dug from the battlefield itself. On top stands a cast iron lion weighing twenty-eight tonnes.
