Harvard Square & Old Cambridge

The center of American higher education since 1636, Harvard Square layers Massachusetts Hall, a library built in memory of a Titanic victim, and the common where Washington took command.

A campus is an argument in brick about what education is for. Cambridge has a long-running one. Seven stops over 1.0 miles, about an hour of walking. Every stop narrates itself when you get there, at whatever pace you feel like walking.

It is one of eight tours in Cambridge, each taking a different line through the city. Nothing is booked and nothing expires, so you can start it on a whim and finish it whenever you like.
