With photos that span 150 years, Boston Then and Now shows how the largest city in New England has adapted to change as it has grown. Many of the key places in the Revolutionary struggle are featured in the book, including Boston Harbor, Paul Revere's house and Dorchester Heights, from where George Washington threatened the British garrison.

The book shows how the Big Dig has transformed the city, which despite the march of the 21st century has managed to preserve a large part of its remarkable history.

Sites include: Boston Light, USS Constitution, Bunker Hill Monument, Old North Church, Charles Street Jail, Scollay Square, Union Oyster House, Quincy Market, Faneuil Hall, Dock Square, Old State House, Massachusetts State House, Boston Common, Old South Meeting House, Long Wharf, South Station, Liberty Tree Site, Copley Square, Boston Public Library, Museum of Fine Arts, Fenway Park, Kenmore Square and Cyclorama.
