A downtown walk past the surgery, subway, and switchboard that started American firsts
Boston was built to make things, and the buildings still say so. Six stops over 2.3 miles, about an hour and a half of walking. The story for each stop plays as you arrive, so nothing has to be looked up and nobody has to be followed.
Boston has 50 MassRoam tours and no two cover the same ground. It works as well at eight in the morning as it does at dusk. Stop for coffee, pick it back up.
