The Vatican Museums are pluralized for a reason—within the complex there are several individual museums. It’s easy for them to blur together as you wander through, but different collections are housed under different “museum” names. One such collection is the Chiaramonti Museum, sometimes called the Chiaramonti Gallery (Galleria Chiaramonti in Italian). The name comes from Pope Pius VII, who established the museum in 1807 and gave the museum his family name (prior to becoming Pope, of course).
