3. Fort Hamilton’s Rodman Gun

Located at Fourth Avenue and 101st Street in Brooklyn, the Fort Hamilton Rodman Gun is housed in John Paul Jones Park, named after the “father of the navy,” Revolutionary War hero, John Paul Jones.

The 116,000 pound, 20-inch bore columbiad was created by artilleryman Thomas Jackson Rodman in 1864, and designed for Civil War use. Although it was tested at Fort Hamilton, the neighboring army base, it was proved to be unsuitable, and was given to the park by the United States Military in 1900.

Today, the gun is surrounded by cannon balls and takes up a significant part of the landscape.
