Star Forts Are Military History, and the Base of Some Strange Conspiracy Theories
4/15/2024

On an unseasonably cold day in late March, I took a nearly empty ferry to Governor’s Island in New York Harbor. The sun was shining, but a brutal, frigid wind meant it was hardly a day for a picnic, a popular reason to visit the island in the summer. I disembarked onto a nearly deserted island, one that would have been utterly quiet if not for the near-constant sound of private helicopters taking off from and landing on the lower tip of Manhattan. I was there to see the star-shaped Fort Jay, a coastal defense built between 1794 and 1806, one of a series of fortifications that once protected the city and its harbor, and recently recast as a historic monument and spot for summer recreation. It’s notable for its striking structure—a kind of five-pointed star, a shape that has led to its inclusion in a strange conspiracy theory about the nature of the past and humanity itself.
