Lion's Mound

The Lion's Mound is a large conical artificial hill in the municipality of Braine-l'Alleud, Walloon Brabant, Belgium. King William I of the Netherlands ordered its construction in 1820, and it was completed in 1826. It commemorates the spot on the battlefield of Waterloo where the king's elder son, Prince William of Orange, is presumed to have been wounded on 18 June 1815, as well as the Battle of Quatre Bras, which had been fought two days earlier.

The hill offers a vista of the battlefield, and is the anchor point of the associated museums and taverns in the surrounding Lion's Hamlet. Visitors who pay a fee may climb up the mound's 226 steps, which lead to the statue and its surrounding overlook; the same fee also grants admission to see the painting Waterloo Panorama.
