Boston Public Library
This venerable institution is a handsome temple to reading and a valuable research library, as well as an art gallery of sorts, and you don't need a library card to enjoy it. At the main entrance hall of the 1895 Renaissance Revival building, take in the immense stone lions by Louis St. Gaudens, the vaulted ceiling, and the marble staircase. The corridor at the top of the stairs leads to Bates Hall, one of Boston's most sumptuous interior spaces. This is the main reading room, 218 feet long with a barrel vault ceiling 50 feet high. The murals at the head of the staircase, depicting the nine muses, are the work of the French artist Pierre Puvis de Chavannes; those in the room to the right are Edwin Austin Abbey's interpretations of the Holy Grail legend. Upstairs, in the public areas, is John Singer Sargent's mural series Triumph of Religion. The library offers free art and architecture tours. The McKim building contains a Renaissance-style courtyard inspired by Rome's Palazzo della Cancelleria. A covered arcade furnished with chairs rings a fountain; you can bring books or lunch into the peaceful courtyard.
