Northwest (Washington, D.C.) in the context of "16th Street (Washington, D.C.)"

The White House is the official residence and workplace of the president of the United States. Located at 1600 Pennsylvania Avenue NW in Washington, D.C., it has served as the residence of every U.S. president since John Adams in 1800 when the national capital was moved from Philadelphia. The White House is also a metonym for the Executive Office of the President.

The residence was designed by the Irish-born architect James Hoban in the Neoclassical style. Hoban modeled the building on Leinster House in Dublin, a building which today houses the Oireachtas, the Irish legislature. Constructed between 1792 and 1800, its exterior walls are Aquia Creek sandstone painted white. When Thomas Jefferson moved into the house in 1801, he and his architect Benjamin Henry Latrobe added low colonnades on each wing to conceal what then were stables and storage. In 1814, during the War of 1812, the mansion was set ablaze by British forces in the burning of Washington, destroying the interior and charring much of the exterior. Reconstruction began almost immediately, and President James Monroe moved into the partially reconstructed Executive Residence in October 1817. Exterior construction continued with the addition of the semicircular South Portico in 1824 and the North Portico in 1829.

Georgetown is a historic neighborhood and commercial district in Northwest Washington, D.C., situated along the Potomac River. Founded in 1751 as part of the colonial-era Province of Maryland, Georgetown predated the establishment of Washington, D.C. by 40 years. Georgetown was an independent municipality until 1871 when the United States Congress created a new consolidated government for the entire District of Columbia. A separate act, passed in 1895, repealed Georgetown's remaining local ordinances and renamed Georgetown's streets to conform with those in Washington, D.C.

The primary commercial corridors of Georgetown are the intersection of Wisconsin Avenue and M Street, which contain high-end shops, bars, restaurants, and Georgetown Park, an enclosed shopping mall. Washington Harbour, which includes waterfront restaurants, is located to the south on K Street between 30th and 31st Streets.

14th Street NW/SW is a street in Northwest and Southwest quadrants of Washington, D.C., located 1.25 miles (2.01 km) west of the U.S. Capitol. It runs from the 14th Street Bridge north to Eastern Avenue.

Northbound U.S. Route 1 runs along 14th Street from the bridge to Constitution Avenue, where it turns east with US 50. US 1 southbound previously used 15th Street NW due to the ban on left turns from westbound Constitution Avenue to 14th Street, but it now uses the Ninth Street Tunnel, five blocks to the east. 14th Street crosses the National Mall and runs near the White House and through the western side of Washington's Logan Circle neighborhood.

The United States Naval Observatory (USNO) is a scientific and military facility that produces geopositioning, navigation and timekeeping data for the United States Navy and the United States Department of Defense. Established in 1830 as the Depot of Charts and Instruments, it is one of the oldest scientific agencies in the United States, and remains the country's leading facility for astronomical and timing data.

The observatory is located in Northwest Washington, D.C. at the northwestern end of Embassy Row. It is among the few pre-20th century astronomical observatories located in an urban area. In 1893, in an effort to escape light pollution, it was relocated from Foggy Bottom near the city's center, to its Northwest Washington, D.C. location.

Wisconsin Avenue is a major thoroughfare in Washington, D.C., and its Maryland suburbs. The southern terminus begins in Georgetown just north of the Potomac River, at an intersection with K Street under the elevated Whitehurst Freeway. Wisconsin Avenue ends just north of Bethesda, Maryland—though the road designated as Maryland Route 355 continues north for miles under the name of Rockville Pike.

Foggy Bottom is a neighborhood of Washington, D.C., United States, located in the city's northwest quadrant. It stretches west of the White House towards the Potomac River, north of the National Mall, east of Georgetown, south of the West End neighborhood and west of Downtown D.C.

The neighborhood is best known for hosting the headquarters of the U.S. Department of State, for which the name "Foggy Bottom" is commonly used as a metonym. It is also home to federal agencies and international institutions, including the Federal Reserve, the World Bank, and the International Monetary Fund; the core of the neighborhood is occupied by George Washington University.

Downtown is the central business district of Washington, D.C., located in Northwest D.C. It is the third largest central business district in the United States. The "Traditional Downtown" has been defined as an area roughly between Union Station in the east and 16th Street NW in the west, and between the National Mall on the south and Massachusetts Avenue on the north, including Penn Quarter. However, nowadays, Downtown D.C. can often refer to a larger area, as the DC Office of Planning states:

A small portion of this area is known as the Downtown Historic District and was listed on the NRHP in 2001.
