This work explores Boston’s past and present: 12 walks that trace the creation of the city’s man-made land in the central waterfront, Back Bay, South End, Charlestown, and elsewhere. At its founding, Boston was a small peninsula; over the last 375 years the city has doubled in size by filling in the surrounding tidal flats - areas covered with water at high tide and exposed at low. In Walking Tours of Boston’s Made Land , historian Nancy S. Seasholes outlines twelve walks that trace where and why Boston’s man-made land was created, and, along the way, uncovers fascinating and little-known pieces of Boston history. In the course of these walks - around the central waterfront, Back Bay, Beacon Hill, the South End, Charlestown, and elsewhere - she shows us how Boston’s past is always just below the surface of its present.
