Town and a former commune in the Côtes-d'Armor department in Brittany in northwestern France. Charles Armand Tuffin, marquis de la Rouërie, hero of the American war of independence, died near Lamballe in 1793. Chilean dictator Augusto Pinochet's ascendant, Guillaume Pinochet, was a Lamballe native of Breton descent. He migrated to then-Spanish Chile in the 18th century. These days it's the home of one of the largest pig slaughterhouses in France.
