In the season five premiere, Sarah and Bruce welcome construction engineering experts Harry Berlis and Tom Fennick of McPHAIL ASSOCIATES, LLC, who intrigue with their knowledge of the history of Back Bay. Before it became brownstones and boutiques, Back Bay was precisely that—a bay. In the 1800s, Boston launched a massive land-filling project that transformed water and marsh into one of the city’s most iconic neighborhoods. This episode dives into the bold engineering, political will, and sheer volume of dirt that built Back Bay from the ground up and how it still stands today!
