Boston Public Library was founded in 1848 as the first large free municipal library in America. Charles Follen McKim's 1895 building carries the words "Free to All" over the door and was called a "palace for the people" deliberately. Bates Hall runs 218 feet with a barrel-vaulted ceiling 50 feet up, and the room still enforces quiet on its own. John Singer Sargent spent nearly thirty years painting the murals upstairs. Puvis de Chavannes and Daniel Chester French also worked on it.
