7. Little Red Lighthouse
The Little Red Lighthouse, known officially as Jeffrey’s Hook Light, is situated underneath the George Washington Bridge. As one of the few surviving lighthouses in New York City, the structure – built in 1880 and moved to its current site in 1921 – still serves as a reminder of the area’s history. Using its 1,000 pound fog bell and red flashing light, the lighthouse used to guide ships from Sandy Hook, New Jersey. It has remained out of operation since 1917.
