Experience the revival to this historic part of Boston on a 3-mile walk along Washington Street led by BHV member Roger Cox. The dismantling of the “El” in the 1980s set the stage for the development of this broad boulevard. Among the sights are the Gothic Cathedral of the Holy Cross, elegant Blackstone and Franklin Squares, and the South End Burying Ground. Optional lunch after walk. Meet outside Tufts Medical Center T Station on the Orange Line at 10 a.m. BHV members and guests. Free.
