Boston Underfoot Walking Tour

Trace the evolution of Boston from a tiny peninsula through to the Big Dig. Walking from Boston's oldest alleys to the Greenway, this tour presents the engineering of a city.

Follow Boston's great engineering feats from the filling of the Back Bay to the Big Dig, now America's largest public works project. Walk through the new Rose Kennedy Greenway and some of Boston's oldest alleys. Ride the nation's first subway and learn about such taken-for-granted utilities as water, sewage, gas, steam, and electricity.

Join us for this unique look at Boston where most of the sightseeing takes place around your feet! Learn the origin of manholes, the different ways to engineer a tunnel, the secret identities of some of Boston's newest buldings, and what was so big about a recent dig.
