About Baltimore, Towson, and Annapolis, Maryland

Baltimore is the largest city in the U.S. state of Maryland, and the 29th-most populous city in the country. It was established by the Constitution of Maryland and is not part of any county; thus, it is the largest independent city in the United States, with a population of 621,849 as of 2015. As of 2010, the population of the Baltimore Metropolitan Area was 2.7 million, making it the 21st largest in the country. Founded in 1729, Baltimore is the second largest seaport in the Mid-Atlantic. Baltimore's Inner Harbor was once the second leading port of entry for immigrants to the United States and a major manufacturing center. After a decline in major manufacturing, industrialization and rail transportation, Baltimore shifted to a service-oriented economy, with the Johns Hopkins Hospital (founded 1889), and Johns Hopkins University (founded 1876), now the city's top two employers. With hundreds of identified districts, Baltimore has been dubbed "a city of neighborhoods". Famous residents have included the writers Edgar Allan Poe, Edith Hamilton, Frederick Douglass, and H.L. Mencken ; jazz musician James "Eubie" Blake ; singer Billie Holiday ; actor and filmmaker John Waters ; and baseball player Babe Ruth. In the War of 1812, Francis Scott Key wrote The Star-Spangled Banner, later the American national anthem, in Baltimore. Baltimore has more public monuments per capita than any other city in the country and is home to some of the earliest National Register historic districts in the nation, including Fell's Point (1969), Federal Hill (1970) and Mount Vernon Place (1971). More than 65,000 properties, or roughly one in three buildings in the city, are listed on the National Register, more than any other city in the nation.

Towson is an unincorporated community and a census-designated place in Baltimore County, Maryland. The population was 55,197 at the 2010 census. It is the county seat of Baltimore County and the second-most populated unincorporated county seat in the United States (after Ellicott City, Maryland in nearby Howard County).

Annapolis is the capital of the U.S. state of Maryland, as well as the county seat of Anne Arundel County. Situated on the Chesapeake Bay at the mouth of the Severn River, 25 miles (40 km) south of Baltimore and about 30 miles (50 km) east of Washington, DC, Annapolis is part of the Baltimore–Washington metropolitan area. Its population was measured at 38,394 by the 2010 census.The city served as the seat of the Continental Congress in 1783–84 and was the site of the 1786 Annapolis Convention (which called for the Constitutional Convention held the following year) and the Annapolis Peace Conference, held in 2007. Annapolis is the home of St. John's College as well as the United States Naval Academy.
