Building Boston, Shaping Shorelines is a Harvard Map Collection exhibition going on now at Harvard Library’s Pusey Library Gallery. “This exhibition allows you to trace the projects to reclaim land and build the infrastructure that has produced a city out of a peninsula. Come learn how much of Boston is on man-made land and what impacts that has had and will have on the city.” There is no online version, but Harvard Magazine has a writeup. Until 1 May 2020.
