Baltimore is a major city in Maryland with a long history as an important seaport. Fort McHenry, birthplace of the U.S. national anthem, “The Star-Spangled Banner,” sits at the mouth of Baltimore’s Inner Harbor. Today, this harbour area offers shops, upscale crab shacks and attractions like the Civil War–era warship the USS Constellation and the National Aquarium, showcasing thousands of marine creatures. Founded in 1719, Baltimore is the second largest seaport in the Mid-Atlantic. Baltimore had a population of 611,104 in 2013. The city is rich in architecturally significant buildings in a variety of styles. The Baltimore Visitor Center, which is operated by Visit Baltimore, is located on Light Street in the Inner Harbor. Much of the city's tourism centers around the Inner Harbor, with the National Aquarium being Maryland's top tourist destination. Other popular tourist destinations throughout the city include Oriole Park at Camden Yards, Fort McHenry, the Mount Vernon and Fells Point neighborhoods, and museums such as the Walters Art Museum, Sports Legends Museum at Camden Yards and the Baltimore Museum of Industry.
