About this map
In 1836 the local leadership initiated the community's transition from a "swampish hamlet" to a busy port town. The 22 acres of the harborfront, which flooded at high tide, were brought to a stable elevation with the construction of a causeway. The village changed its name from "Drowned Meadow" to "Port Jefferson", in honor of Thomas Jefferson.
