Name and history
According to a legend, the name (meaning "broken bit") derives from an event during the Carthaginian invasion of Italy (218–201 BC), when Hannibal allegedly broke here the bit of his horse. The event is also remembered in the city's coat of arms. In reality the name is from the Lombard roth ("glory") and fridu ("friendship", "safeness"). The village was in fact called Rottofredo during the Middle Ages.
On 12 August 1746 during the War of Austrian Succession, a battle was fought here between a French-Spanish army and an Austrian force. This event is known as the Battle of Rottofredo (or Rottofreddo).
