Monument aux Hanovriens, Protected heritage monument in Lasne, Belgium

The Monument aux Hanovriens is an 1818 memorial on the Waterloo battlefield near La Haye Sainte, built of limestone as a truncated pyramid. It stands on a small mound enclosed by an iron fence, with a stepped base, a tapering shaft, a raised band below the overhanging top slab, and two small openings near the summit. A carved inscription on the front face is now faint.

The monument was built in 1818 to honor 42 officers from the Anglo-German Legion who died during the French attacks at La Haie Sainte in Waterloo. It was created shortly after the Napoleonic Wars to preserve the memory of these international soldiers.

The monument was erected in 1818 by Hanoverian officers of the King's German Legion, the unit raised after the French invasion of Hanover in 1803. Its German name, Denkmal für die Hannoveraner, is still used locally. The KGL also defended the farmhouse of La Haye Sainte during the battle, close to the memorial.

The monument is located about 500 meters east of the Lion's Mound and sits southeast of the intersection between Chaussée de Charleroi and Route du Lion. This position makes it relatively easy to find when you are exploring the Waterloo battle area on foot or by car.

The monument was erected in 1818 by Hanoverian officers of the King's German Legion themselves, not by a state commission. It stands on a small mound raised above the flat plain, like the nearby Gordon Monument, and is enclosed by an iron grille.
