Waterloo is a town south of Brussels, in Belgium. It’s known as the site of the final defeat of Emperor Napoleon I, in 1815. South of town, overlooking the battlefield, the Lion’s Mound is an artificial hill topped by a cast-iron lion. At its foot is a rotunda housing the Panorama of the Battle, a vast circular painting. Nearby, the Memorial 1815 is an underground center illustrating the battle’s historic importance.
