The image of Napoleon Bonaparte is closely linked to the city of Monza: the iron crown with which he was crowned King of Italy on May 26, 1805 in Milan Cathedral is today preserved in the altar of the Theodolinda's Chapelin the Duomo of the city, a copy of which was installed on Napoleon's sarcophagus when his body was brought back to Paris from the island of St. Helena.
Since 2023, Monza has joined the European Federation of Napoleonic Cities, consolidating its historical link with the Napoleonic era through an important international collaboration.
