Since its founding at the 1876 Centennial Exhibition, the Philadelphia Museum of Art has accumulated one of the world’s leading art collections with 240,000 works spanning 4,000 years of human creativity. The museum primarily serves a ten-county metro area with six million residents and receives some 700,000 visitors every year. To serve those visitors, the museum presents sixteen to twenty special exhibitions and creates educational programs—designed to fit learners of all ages—for more than 200,000 participants annually.
