The Helen Delich Bentley Port of Baltimore is a shipping port along the tidal basins of the three branches of the Patapsco River in Baltimore, Maryland, on the upper northwest shore of the Chesapeake Bay. It is the nation's largest port facility for specialized cargo (roll-on/roll-off ships) and passenger facilities. It is operated by the Maryland Port Administration (MPA), a unit of the Maryland Department of Transportation.

Founded in 1706, the port was renamed in 2006 for Helen Delich Bentley (1923–2016), who represented Baltimore as a U.S. Representative for a decade and who had also been a maritime reporter and editor for The Baltimore Sun daily newspaper.

Fort McHenry is a historical American coastal pentagonal bastion fort on Locust Point, now a neighborhood of Baltimore, Maryland. It is best known for its role in the War of 1812, when it successfully defended Baltimore Harbor from an attack by the British navy from Chesapeake Bay on September 13–14, 1814.

The fort was built in 1798 and was used continuously by U.S. armed forces through World War I and by the United States Coast Guard in World War II. It was designated a national park in 1925, and, in 1939, was redesignated a U.S. National Monument.

The Patapsco River (/pəˈtæpˌskoʊ/ pə-TAP-skoh ) mainstem is a 39-mile (63 km) river in central Maryland that flows into Chesapeake Bay. The river's tidal portion forms the harbor for the city of Baltimore. With its South Branch, the Patapsco forms the northern border of Howard County, Maryland. The name "Patapsco" is derived from the Algonquian pota-psk-ut, which translates to "backwater" or "tide covered with froth".

The Great Baltimore Fire raged in Baltimore, Maryland from Sunday February 7 to Monday February 8, 1904. In the fire, more than 1,500 buildings were completely leveled, and some 1,000 severely damaged, bringing property loss from the disaster to an estimated $100 million. 1,231 firefighters helped bring the blaze under control, both professional paid truck and engine companies from the Baltimore City Fire Department (B.C.F.D.) and volunteers from the surrounding counties and outlying towns of Maryland, as well as out-of-state units that arrived on the major railroads. It destroyed much of central Baltimore, including over 1,500 buildings covering an area of some 140 acres (57 ha).

From North Howard Street in the west and southwest, the flames spread north through the retail shopping area as far as Fayette Street and began moving eastward, pushed along by the prevailing winds. Narrowly missing the new 1900 Circuit Courthouse, now the Clarence M. Mitchell Jr. Courthouse, fire passed the historic Battle Monument Square from 1815 to 1827 at North Calvert Street, and the quarter-century-old Baltimore City Hall, built in 1875 on Holliday Street; and finally spread further east to the Jones Falls stream which divided the downtown business district from the old East Baltimore tightly-packed residential neighborhoods of Jonestown (also known as Old Town) and newly named "Little Italy". The fire's wide swath burned as far south as the wharves and piers lining the north side of the old "Basin" (today's "Inner Harbor") of the Northwest Branch of the Baltimore Harbor and Patapsco River facing along Pratt Street.

Downtown Baltimore is the central business district of the city of Baltimore traditionally bounded by Martin Luther King, Jr. Boulevard to the west, Franklin Street to the north, President Street to the east and the Inner Harbor area to the south.

In 1904, downtown Baltimore was almost destroyed by a huge fire with damages estimated at $150 million. Since the City of Baltimore was chartered in 1796, this downtown nucleus has been the focal point of business in the Baltimore metropolitan area. It has also increasingly become a heavily populated neighborhood with over 37,000 residents and new condominiums and apartment homes being built steadily.
