The National Historic Seaport of Baltimore is among America's oldest seaports — more than 300 years old. This byway connects Baltimore's many historic waterfront communities, whose rich heritage enhances today's vital and thoroughly modern seaport. It is managed by the nonprofit Living Classrooms Foundation — a not-for-profit educational organization. Since the 1600s, the deep-water Port of Baltimore has welcomed ships conveying people and goods from all over the world. The seaport comprises 15 sites, including seven National Historic Landmarks such as the USS Constellation and the Submarine Torsk. The Baltimore Maritime Museum, the Top of the World Observation Tower, the Baltimore Museum of Industry, and the Civil War Museum are some of the other maritime attractions in various locations around the Inner Harbor. The admission to those sites can be obtained through seaport pass cards and day passes. The Baltimore Maritime Museum is a combination of the 1833 Seven Foot Knoll Lighthouse and three historic ships: the Coast Guard cutter Taney (a survivor of the attack on Pearl Harbor), the World War II-era Torsk, and the Lightship Chesapeake. The seaport creates an exciting, educational experience for visitors and residents, with opportunities for family fun and entertainment in the harbor by exploring its maritime history. The facilities provided include meeting rooms, the hosting of company events, or entertaining clients on a historic Civil War-era tall ship. Special programs also are arranged. Water transportation to Baltimore's only National Park Service site, Fort McHenry National Monument and Historic Shrine, is available via the Seaport Taxi. The surrounding historic neighborhoods of Federal Hill, Canton, and Fells Point, are also worth a visit.
