Description: Fort Corkscrew was built in 1776, at the beginning of the Revolutionary War, in Brooklyn, New York. Two of the three names given to the fort, “Fort Corkscrew” and “Spiral Fort” originate from the construction’s unique entrenchments which wound up around the hill on which it was situated. General, Founding Father, and eventual President, George Washington, viewed fighting from the fort in August of 1776. That same year, along with the rest of the city, Fort Corkscrew fell under British occupation. The structure was dismantled by the British in the summer of 1781.
