The La Ronde mansion was looted and heavily damaged by the British during the fateful Night Attack of December 23, 1814, which effectively launched the Battle of New Orleans, then further ruined when commandeered by the British as a field hospital. The house then burned about 70 years later, though most of the walls remained standing until the hurricane of 1915. A few ruins remain visible along Highway 46 in St. Bernard Parish, as does the Southern live oak "allée" that once graced the path from the Mississippi River landing to the manor house.
