Book excerpt: Originally a narrow, barren strip of land known as the Neck, Boston's South End grew from a lonely sentry post and execution grounds to what is today the largest Victorian neighborhood in the United States. With the filling of the South Cove in the 1830s, the area became one of the greatest planned residential districts of its time, a heritage preserved in unique architectural features such as red brick swell bay facades, elaborate balusters, and fanciful porches.
