Beacon Street Roofs (unfinished)

Beacon Street initially formed the northern limit of Boston Common, and was extended over the Charles River Basin as a dam that would later form the shore between a narrowed river and the newly filled-in Back Bay neighborhood. The part of Beacon Street west of Kenmore Square was originally laid out in 1850. Railroad tracks were first laid in 1888 for what would eventually become the modern Green Line C branch.
