This internationally recognized museum houses one of the most important collections from the Napoleonic era; it's undoubtedly one of the most significant displays in France of ancient Italian masterpieces spanning the 14th to 20th century. There are nearly 18,000 items, all part of an astounding inventory that belonged to Napoléon's uncle, Cardinal Fesch. Thanks to his nephew's military conquests, the cardinal was able to amass (steal, some would say) many celebrated old master paintings, the most famous of which are now in Paris's Louvre. The museum's beautiful vaulted corridors showcase 700 paintings, portraits, still lifes, and sculptures from the First and Second Empire from the French school. Don't miss the new gallery with engravings and drawings depicting historic Corsica. The building itself, constructed by the cardinal as the Institute of Arts and Sciences, dates back to 1837.
