- The Village’s shipbuilding industry spanned over a century, from approximately 1797 (when its first shipyard was built) to its close in the 1920’s.
- As a shipbuilding hub, Port Jefferson’s main role was to build and support ships that participated in coastal freighting trades. The Village eventually became the largest shipbuilding industry in Suffolk County.
- Well-known circus owner P.T. Barnum owned a segment of land running through the Village. He aimed to establish Port Jefferson as the home base for his circus, but would eventually sell his land after disapproving residents put a stop to his plans.
