 Napoleon's visits to Fontainebleau were not frequent, because he was occupied so much of the time with military campaigns.Between 1812 and 1814, the château served as a very elegant prison for Pope Pius VII.On 5 November 1810, the chapel of the Chateau was used for the baptism of Napoleon's nephew, the future Napoleon III, with Napoleon serving as his godfather, and the Empress Marie-Louise as his godmother.
