Port Jefferson was originally called Drowned Meadow because the area was tidal and was drowned by the tide twice a day. East Main Street followed the edge of the salt marsh, and was the original Main Street. The Villagers voted to change its name to Port Jefferson in 1836. The Village was the largest shipbuilding center in Suffolk County in the 1800s with four of every ten ships built here. The Village incorporated in 1963.
