1903 Map of Fire Island

On the mainland, the Long Island R. R. Montauk Division links established bayfront communities like Sayville, Bayport, and Bayshore. The map illustrates the development of the South Shore, where estates and small settlements are defined by their proximity to the water, from Nicolls Bay to the mouth of the Connetquot River. This era captures the region as a growing retreat for New Yorkers, balanced between its industrial railroad connections and its primary identity as a seafaring and recreational hub.
