One of the few surviving lighthouses in New York City, this 40-foot-high structure was erected in 1921 but decommissioned by the Coast Guard just 27 years later. Thanks to an outpouring of love inspired by the 1942 children's book <em>The Little Red Lighthouse and the Great Gray Bridge,</em> the lighthouse still stands today next to the George Washington Bridge, delighting visitors to Fort Washington Park with its vibrant red pop of color and striking Hudson River views.
