Quick Facts

Historical/Interpretive Information/Exhibits

Feel the grooves inside this rare cannon barrel. This Rodman cannon was cast in 1861 as a 10-inch smoothbore, which fired round cannonballs. To keep up with current technology, the U.S. Army in 1884 inserted an 8-inch rifled sleeve into the old cast-iron barrel, because rifled guns had longer ranges than smoothbores. Steel later replaced cast iron, and the old guns were sold for scrap. The piece on the right is part of a smoothbore. The piece on the left is part of a rifled bore.

Keep off the Cannon. For your safety and to help preserve this historic cannon, do not climb on the gun barrel.
