"Walk the Freedom Trail Love history? Then don't miss at least part of The Freedom Trail. Two and a half miles of 16 sites steeped in history make up Boston 's version of the 'Yellow Brick Road.' This time, the brown bricks start at the Boston Common, and lead you on a winding outdoor museum tour ending at the U.S.S. Constitution . The gold-domed State House, built in 1798, is where the government now conducts its daily business, and is the first building on the route. Period dressed characters along the way put a fun spin on the activity, and you can either map out your own itinerary after getting a map, or take a guided tour."
