Mona Lisa
The painting is thought to be a portrait of Lisa Gherardini, the wife of Francesco del Giocondo, and is in oil on a white Lombardy poplar panel. It had been believed to have been painted between 1503 and 1506; however, Leonardo may have continued working on it as late as 1517. Recent academic work suggests that it would not have been started before 1513. It was acquired by King Francis I of France and is now the property of the French Republic, on permanent display at the Louvre Museum in Paris since 1797.
Bobbio
Some art historians, including Carla Glori, have suggested that Bobbio and its three-arched Ponte Gobbo (which was destroyed in 1472) are the landscape in the background of Leonardo da Vinci's Mona Lisa.
