The outer harbor of Boston Harbor is defined here by a dense archipelago of islands and narrow navigation channels such as The Narrows and Nubble Channel. Coastal fortifications from several eras are clearly visible, including Fort Warren on Georges Island, Fort Strong on Long Island, and Fort Duvall near Allerton. These installations, alongside the Boston Lighthouse and the Long Island Head Light, illustrate the maritime defense and navigation infrastructure essential to protecting the Massachusetts coastline.
