You may have heard that Bostonians of years past enthusiastically embarked on landmaking ventures, expanding the City’s coastlines to make way for development. But do you know that Charles Street lies on land that was once beyond the shoreline? The western expansion of Beacon Hill onto the tidal flats of the Charles River provided a foundation for residential and commercial expansion, and later for portions of the Esplanade and Storrow Drive. the Flat of the Hill now contains an eclectic array of buildings, early examples of adaptive reuse, and a vibrant commercial district. From tidal flat to historic district, the Flat of the Hill continues its evolution to the current day. On Thusday, May 22, from 5 0 6:30, join City of Boston Preservation Planner Erin Doherty to investigate the history of this transformation. Free and open to the public. Meeting place confirmed at time of reservation. Contact erin.doherty@boston.gov before May 19 to reserve a place (that’s tomorrow!)
