Death
Stefano Visconti (kneeling). Portrait from his grave.
Stefano died in the night of July 4, 1327, after a banquet he gave for the coronation of Louis the Bavarian as King of Italy.
Stefano's contemporaries linked his death to an attempted poisoning of the King, leading to the imprisonment of three of Stefano's four brothers, Galeazzo, Giovanni, and Luchino, as well as of his nephew, the future Lord of Milan, Azzo Visconti, in the fortress of Monza: This event marked a crisis of the relations between the Holy Roman Empire and the Visconti.
The magnificent tomb of Stefano and his wife Valentina, carved in 1359 by Bonino da Campione, is located in the Basilica Sant'Eustorgio in Milan.
