Declared Regent of her eleven-year-old son's dominions, she took her new charge with great interest and ambition. She carried on her husband's work on the properties of Savoy, supporting construction projects, artistic organizations, and educational institutions. She supported the work of Alessandro Stradella, protecting him when he fled to Turin from Venice. She continued to fund and support the work of Guarino Guarini, who completed the chapel for the Shroud of Turin and a Jesuit college under her rule. She also worked to expand the city of Turin down to the Po river. She attempted to start a university in Chambéry, but was not successful.
