While on break at a water conference in Boston, I wandered out for coffee and to see the Boston Commons.  On the way, I noticed this small cemetery surrounded by red brick apartment buildings and modern retail areas on Tremont Street right by the Park Street subway station.   This is the Old Granary Burying Ground which dates back to 1660.  Paul Revere, John Hancock, and Samuel Adams are interred here as is Crispus Attucks, the runaway slave who was the first African-American casualty of the War of Independence.  Even though the cemetery is surrounded by buildings, crowded sidewalks, and busy streets, there is still a certain serenity about this burial ground.  The freshly fallen oak leaves made for a beautiful contrast with the cold gray headstones and you can almost feel the spirits of the victims of the Boston Massacre.  There is a guided tour of the cemetery that is quite informative, or you can just do like I did and soak it up on your own.  Either way it was a delightful break from the conference, which I got back to about two hours late.
