The American Visionary Art Museum (AVAM) is an art museum located in Baltimore, Maryland's Federal Hill neighborhood at 800 Key Highway. The museum specializes in the preservation and display of outsider art. The city agreed to give the museum a piece of land on the south shore of the Inner Harbor under the condition that its organizers would clean up residual pollution from a copper paint factory and a whiskey warehouse that formerly occupied the site. It has been designated by Congress as America's national museum for visionary art.

The Maryland Science Center (MSC), located in Baltimore's Inner Harbor, opened to the public in 1976. It includes three levels of exhibits, a planetarium, and an observatory. It was one of the original structures that drove the revitalization of the Baltimore Inner Harbor from its industrial roots to a thriving downtown destination. In 1987, an IMAX theater was added, but the museum continued to show its age as the end of the 20th century approached. In May 2004, a large addition to the property was opened, and the modernized hands-on exhibits now include more than two dozen dinosaur skeletons. Subjects that the center displays include physical science, space, and the human body.

USS Constellation is a sloop-of-war, the last sail-only warship designed and built by the United States Navy. She was built at the Gosport Shipyard between 1853 and 1855. She was named for the earlier frigate of the same name that had been broken up in 1853. The sloop's primary armament was 8-inch (203 mm) shell-firing guns and four 32-pounder long guns, though she carried other guns as well, including two Parrott rifle chase guns. Constellation's career as a front-line unit was relatively short; after entering service in 1855, she served with the Mediterranean Squadron until 1858, and in 1859, she was assigned as the flagship of the Africa Squadron, where she served with the African Slave Trade Patrol. During the American Civil War (1861–1865), the ship returned to the Mediterranean to patrol for Confederate vessels. In late 1864, she returned to the United States to be decommissioned, as most of her crews' enlistments had expired. She spent the rest of the war out of service.
