About this map

The coastal defenses and marine geography of Boston Bay appear in fine detail at the turn of the twentieth century. From the sprawling public forest at Lynn Woods down to the rocky outcroppings of Cohasset, the map documents a maritime landscape defined by its islands and harbor fortifications. Military significance is centered on Georges I. with the presence of Ft. Warren, while the intricate network of channels like The Narrows guides traffic past navigational markers such as Egg Rock L.H. and the Boston L.H. lighthouse.

Industrial and leisure transport is dominated by the Boston Revere Beach and Lynn RR, which connects coastal settlements from Peabody through Revere Beach and Beachmont. The layout of the peninsula at Hull and the surrounding Hingham Bay shows the era's established maritime communities at Allerton and Nantasket, illustrating how the coastline was utilized before modern redevelopment changed the harbor's footprint.
