Boston: A history written in stone

This combination virtual and walking tour consists of an introduction to Boston geology and quarrying history.

The virtual tour will be followed by a walking segment to view various types of stone utilized in Boston's building construction. The walking segment starts by touching on the glacial geology of Boston as seen on the horizon from the Harborwalk, and discussing the mile of ice which covered the area 20,000 years ago.

We'll then walk over to the Greenway above the Big Dig. Here, there are beautiful examples of hand-carved Quincy granite blocks and more recent saw-cut Chelmsford granite, highlighting the changes in granite types and shaping technologies used through time.


This is a free event, but you need to register. We'll add a registration link in late April.
