2. Boston Public Library (McKim Building)
Silence hits you the moment you step into Bates Hall. The soaring barrel-vaulted ceiling and green lamps create an academic atmosphere that costs absolutely nothing to absorb.

Insider tip: You must pass through a military security checkpoint. Bring a valid government-issued photo ID, or you will not get on the ship.
