What Was Here Before#

The Back Bay was tidal mudflats until the 1850s–1880s landfill (gravel brought by rail from Needham, 24 hours a day at peak). The Hynes site, in the western portion near Gloucester and Dalton Streets, was filled around 1871–1880. For the next 70+ years, the site was occupied by Boston & Albany Railroad rail yards — freight operations, coach storage, and maintenance facilities. The residential brownstone grid of Back Bay (Commonwealth Ave, Marlborough, Beacon) developed to the north; the rail yards were the southern boundary.
