The Full Revolution

Boston to Lexington and Concord and back — the road to war, mile by mile

This is where Boston worked out what kind of place it wanted to be. Six stops over 44.3 miles, about two hours of driving. Each one starts talking the moment you reach it, so you can keep your eyes on the street instead of a screen.

Of the 50 MassRoam tours in Boston, this is the heritage one. There is no start time to make — walk it in one go, or leave the rest for another afternoon.
