Port Jefferson
 
Port Jefferson was first settled in the 17th century and remained a rural community until its development as an active shipbuilding center in the mid-19th century. The village has since transitioned to a tourist-based economy. The port remains active as terminus of the Bridgeport & Port Jefferson Ferry, one of two commercial ferry lines between Long Island and Connecticut, and is supplemented by the terminus of the Long Island Rail Road's Port Jefferson Branch.
