Do not hesitate to visit the Barnes Foundation Museum when you go to the American city of Philadelphia, it is an art museum par excellence that houses a unique collection of more than 4,000 pieces of art, including more than 900 paintings valued at about $25 billion. These are primarily works by masters of the Impressionist and Post-Impressionist art period and by modernist artists, but the collection also includes many other paintings by notable European and American artists, as well as African art, antiquities from China, Egypt, Greece, and Native American art.
