2. There Was a Cemetery at the Brooklyn Navy Yard

More than 2,000 military service members and their families were once buried at the Brooklyn Naval Hospital Cemetery, established in 1831. The site closed in 1910, and the remains were consequently reinterred at Cypress Hills National Cemetery in Brooklyn. However, during a field investigation in 1997, additional remains were discovered and later preserved at the location. Although the cemetery was put out of commission, the landscape recently opened to the public for the first time in 90 years, functioning as an accessible green space.
