While exploring the Revolutionary War/War of 1812 forts on the Secret Places of Central Park tour you’ll come upon a fortification which includes a genuine British cannon from the Revolutionary War. Salvaged from the H.M.S. Hussar after shipwrecking off the East River in 1780, it was eventually donated to Central Park. After being put into storage for a number of years, the Central Park Conservancy, in their plans to restore the Revolutionary War/War of 1812 fortifications, planned to put the artillery piece back on display. While restoring it in 2013, they found a cannonball, wadding, and frighteningly enough, over a pound of gunpowder, making this, in theory, a still-loaded cannon since 1780. The Bomb Squad were called to remove the explosive material, and eventually, it was put back on display for you to see!
