The USS Constellation Historic Ships Museum is a collection of five national historic landmark sites along the Inner Harbor. These sites include the USS Constellation, the last all-sail warship built by the U.S. Navy and the last Civil War era vessel still afloat; the USS Torsk, the submarine that dispatched the last enemy vessel in Word War II; the USSCGC Taney, the last surviving warship from the attack on Pearl Harbor; the Lightship 116 “Chesapeake;” and the Seven Foot Knoll Lighthouse. While touring the ships, visitors will explore the decks to learn about the sailing operations, see the main battery of guns, the Captain’s Cabin, and where the crew lived and socialized, as well as a navigation station, operation station, and an engine room. Children 6 years old and up are invited to take part in the Powder Monkey Tour at the USS Constellation to learn about the young boys who served as powder monkeys during the Civil War.
