About Back Bay
Back Bay is Boston's most iconic neighborhood — home to Copley Square, Newbury Street shopping, the Boston Public Library, and the Prudential Tower. Built on landfilled tidal flats in the 1850s-1880s, the grid of Victorian brownstones houses young professionals, medical residents, and Berklee/BU students. Walk-in care options are anchored by Mass General Brigham's downtown facilities and MinuteClinic locations on Boylston and Mass Ave.
