Back Bay (Boston) in the context of "Beacon Street"

Beacon Street is a major east–west street in Boston, Massachusetts, and its western suburbs of Brookline and Newton. It passes through many of Boston's central and western neighborhoods, including Beacon Hill, Back Bay, Fenway–Kenmore, the Boston University campus, Brighton, and Chestnut Hill.

It is not to be confused with the Beacon Street in nearby Somerville or others elsewhere.
