National Mall in the context of Tea Party protests

The United States Capitol, often called the Capitol or the Capitol Building, is the seat of the United States Congress, the legislative branch of the federal government. It is located on Capitol Hill at the eastern end of the National Mall in Washington, D.C. Although no longer at the geographic center of the national capital, the U.S. Capitol forms the origin point for the street-numbering system of the district as well as its four quadrants. Like the principal buildings of the executive and judicial branches, the Capitol is built in a neoclassical style and has a white exterior.

Central sections of the present building were completed in 1800, when the 6th U.S. Congress convened there on November 17, 1800, moving the national capital from Philadelphia to Washington, D.C.. The building was partly destroyed in the 1814 Burning of Washington by the British, then was fully restored within five years. The building was enlarged during the 19th century, by extending the wings for the chambers for the bicameral legislature as more states were admitted to the union, with the House of Representatives housed in the south wing and the Senate housed in the north wing. The massive dome was completed around 1866 just after the American Civil War. The east front portico was extended in 1958. The building's Visitors Center was opened in the early 21st century.

The National Gallery of Art is an art museum in Washington, D.C., United States, located on the National Mall, between 3rd and 9th Streets, at Constitution Avenue NW. Open to the public and free of charge, the museum was privately established in 1937 for the American people by a joint resolution of the United States Congress. Andrew W. Mellon donated a substantial art collection and funds for construction.

The core collection includes major works of art donated by Paul Mellon, Ailsa Mellon Bruce, Lessing J. Rosenwald, Samuel Henry Kress, Rush Harrison Kress, Peter Arrell Browne Widener, Joseph E. Widener, and Chester Dale. The Gallery's collection of paintings, drawings, prints, photographs, sculpture, medals, and decorative arts traces the development of Western art from the Middle Ages to the present and includes the largest mobile created by Alexander Calder.

The National Museum of Natural History (NMNH) is a natural history museum administered by the Smithsonian Institution, located on the National Mall in Washington, D.C., United States. It has free admission and is open 364 days a year. With 4.4 million visitors in 2023, it was the third most-visited museum in the United States.

Opened in 1910, the museum on the National Mall was one of the first Smithsonian buildings constructed exclusively to hold the national collections and research facilities. The main building has an overall area of 1.5 million square feet (140,000 m) with 325,000 square feet (30,200 m) of exhibition and public space and houses over 1,000 employees.

Cass Gilbert (November 24, 1859 – May 17, 1934) was an American architect. An early proponent of skyscrapers, his works include the Woolworth Building, the United States Supreme Court building, the state capitols of Minnesota, Arkansas, and West Virginia, the Detroit Public Library, the Saint Louis Art Museum and Public Library. His public buildings in the Beaux Arts style reflect the optimistic American sense that the nation was heir to Greek democracy, Roman law and Renaissance humanism. Gilbert's achievements were recognized in his lifetime; he served as president of the American Institute of Architects in 1908–09.

Gilbert was a conservative who believed architecture should reflect historic traditions and the established social order. His design of the new Supreme Court building in 1935, with its classical lines and small size, contrasted sharply with the large federal buildings along the National Mall in Washington, D.C., which he disliked.

Washington, D.C., is administratively divided into four geographical quadrants of unequal size, each delineated by their ordinal directions from the medallion located in the Crypt under the Rotunda of the Capitol. Street and number addressing, centered on the Capitol, radiates out into each of the quadrants, producing a number of intersections of identically named cross-streets in each quadrant. Originally, the District of Columbia was a near-perfect square but contained more than one settlement; the Capitol was to be the center of the City of Washington. Thus, the Capitol was never located at the geographic center of the whole territory, which was eventually north of the Potomac River, consolidated into one city. (The geographic center was located near the onetime marshy area of the present-day intersection of 17th Street, NW and Constitution Ave.) As a result, the quadrants are of greatly varying size. Northwest is quite large, encompassing over a third of the city's geographical area, while Southwest is little more than a few neighborhoods, large parks, and a military base.

The boundaries of the quadrants are not necessarily straight lines radiating from the medallion, but in three instances follow the paths of the boundary streets (which in some cases curve around topographical features): North Capitol Street, South Capitol Street, and East Capitol Street. The axis of the National Mall through the Washington Monument and the Lincoln Memorial forms the boundary running west of the medallion.

Southwest (SW or S.W.) is the southwestern quadrant of Washington, D.C., the capital of the United States, and is located south of the National Mall and west of South Capitol Street. It is the smallest quadrant of the city, and contains a small number of named neighborhoods and districts, including Bellevue, Southwest Federal Center, the Southwest Waterfront, Buzzard Point, and the military installation known as Joint Base Anacostia–Bolling.

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 Hirshhorn Museum and Sculpture Garden is an art museum beside the National Mall in Washington, D.C., United States. The museum was initially endowed during the 1960s with the permanent art collection of Joseph H. Hirshhorn. It was designed by architect Gordon Bunshaft and is part of the Smithsonian Institution. It was conceived as the United States' museum of contemporary and modern art and currently focuses its collection-building and exhibition-planning mainly on the post–World War II period, with particular emphasis on art made during the last 50 years.

The Hirshhorn is situated halfway between the Washington Monument and the US Capitol, anchoring the southernmost end of the so-called L'Enfant axis (perpendicular to the Mall's green carpet). The National Archives/National Gallery of Art Sculpture Garden across the Mall, and the National Portrait Gallery/Smithsonian American Art building several blocks to the north, also mark this pivotal axis, a key element of both the 1791 city plan by Pierre L'Enfant and the 1901 MacMillan Plan.

The Tea Party movement was an American fiscally conservative political movement within the Republican Party that began in 2007, catapulted into the mainstream by Congressman Ron Paul's presidential campaign. The movement expanded in response to the policies of Democratic president Barack Obama and was a major factor in the 2010 wave election in which Republicans gained 63 House seats and took control of the U.S. House of Representatives.

Participants in the movement called for lower taxes and for a reduction of the national debt and federal budget deficit through decreased government spending. The movement supported small-government principles and opposed the Affordable Care Act (also known as Obamacare), President Obama's signature health care legislation. The Tea Party movement has been described as both a popular constitutional movement and as an "astroturf movement" purporting to be spontaneous and grassroots, but alleged to have been influenced by outside interests. The movement was composed of a mixture of libertarian, right-wing populist, and conservative activism. It sponsored multiple protests and supported various political candidates since 2009. The movement took its name from the December 1773 Boston Tea Party, a watershed event in the American Revolution, with some movement adherents using Revolutionary era costumes.

The National Archives Building, known informally as Archives I, is the headquarters of the United States National Archives and Records Administration. It is located north of the National Mall at 700 Pennsylvania Avenue, N.W. in Washington, D.C. The rotunda entrance is on Constitution Avenue, and the research entrance is on Pennsylvania Avenue. A second larger facility, Archives II, also known as A2, is located in College Park, Maryland.

Built in the 1930s, the National Archives Building was designated a contributing property to the Pennsylvania Avenue National Historic Site in 1966 and added to the National Register of Historic Places in 1971. It was designated a National Historic Landmark in December 2023.

The Smithsonian Institution Building, more commonly known as the Smithsonian Castle or simply The Castle, is a building on the National Mall housing the Smithsonian Institution's administrative offices and information center. Built as the first Smithsonian museum building, it is constructed of Seneca red sandstone in the Norman Revival style (a recalling of a 12th-century combination of late Romanesque and early Gothic motifs; built in the Gothic and Romanesque revival styles). It was completed in 1855 and designated a National Historic Landmark in 1965.

Northwest (NW or N.W.) is the northwestern quadrant of Washington, D.C., the capital of the United States, and is located north of the National Mall and west of North Capitol Street. It is the largest of the four quadrants of the city (NW, NE, SW and SE), and it includes the central business district, the Federal Triangle, and the museums along the northern side of the National Mall, as well as many of the District's historic neighborhoods.

Politically, Northwest is made up of parts of Wards 1, 2, 3, 4, 5, and 6, with Wards 1 and 3 being the only wards located entirely within the quadrant. The Northwest is the wealthiest quadrant of the city, particularly west of 16th Street.

Abraham Lincoln (1920) is a colossal seated figure of the 16th president of the United States, Abraham Lincoln (1809–1865), sculpted by Daniel Chester French (1850–1931) and carved by the Piccirilli Brothers. Located in the Lincoln Memorial, constructed between 1914 and 1922 on the National Mall in Washington, D.C., the statue was unveiled in 1922. The work follows in the nation's Beaux Arts and American Renaissance-style architecture traditions.

The Lincoln Memorial is a U.S. national memorial honoring Abraham Lincoln, the 16th president of the United States, located on the western end of the National Mall of Washington, D.C. The memorial is built in a neoclassical style in the form of a classical temple. The memorial's architect was Henry Bacon. In 1920, Daniel Chester French designed the large interior Abraham Lincoln statue, which was carved in marble by the Piccirilli brothers. Jules Guérin painted the interior murals, and the epitaph above the statue was written by Royal Cortissoz. Dedicated on May 30, 1922, it is one of several memorials built to honor an American president. It has been a major tourist attraction since its opening, and over the years, has occasionally been used as a symbolic center focused on race relations and civil rights.

Doric style columns line the temple exterior, and the inscriptions inside include two well-known speeches by Lincoln, the Gettysburg Address, and his second inaugural address. The memorial has been the site of many famous speeches, including Martin Luther King Jr.'s "I Have a Dream" speech delivered on August 28, 1963, during the rally at the end of the March on Washington for Jobs and Freedom.

The Washington Monument is a 555-foot (169 m) tall obelisk on the National Mall in Washington, D.C., built to commemorate George Washington, a Founding Father of the United States and the nation's first president. Standing east of the Reflecting Pool and the Lincoln Memorial, the monument is made of bluestone gneiss for the foundation and of granite for the construction. The outside facing consists of three different kinds of white marble, as the building process was repeatedly interrupted. The monument stands 554 feet 7+11⁄32 inches (169.046 m) tall, according to U.S. National Geodetic Survey measurements in 2013 and 2014. It is the third tallest monumental column in the world, trailing only the Juche Tower in Pyongyang, and the San Jacinto Monument in Houston, Texas. It was the world's tallest structure between 1884 and 1889, after which it was overtaken by the Eiffel Tower, in Paris.

Construction of the presidential memorial began in 1848. The construction was suspended from 1854 to 1877 due to funding challenges, a struggle for control over the Washington National Monument Society, and the American Civil War. The stone structure was completed in 1884, and the internal ironwork, the knoll, and installation of memorial stones was completed in 1888. The original design was by Robert Mills from South Carolina, but construction omitted his proposed colonnade for lack of funds, and construction proceeded instead with a bare obelisk. The completed monument was dedicated on February 21, 1885, and opened to the public on October 9, 1888. In 2001, a temporary security screening facility was added to the entrance. Following the 2011 Virginia earthquake, the monument was closed for repairs until 2014, and it was closed again from 2016 to 2019.

The Harry S Truman Building is the headquarters of the United States Department of State. It is located in Washington, D.C., and houses the office of the United States secretary of state.

The Truman Building is located in the Foggy Bottom neighborhood at 2201 C Street NW, bounded by C Street to the south, E Street, D Street, and Virginia Avenue to the north, 21st Street to the east, and 23rd Street to the west. It is located to the west of Edward J. Kelly Park and north of the National Academy of Sciences building and the National Mall.

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.

The National Museum of African American History and Culture (NMAAHC), colloquially known as the Blacksonian, is a Smithsonian Institution museum located on the National Mall in Washington, D.C., in the United States. It was established in 2003 and opened its permanent home in 2016 with a ceremony led by President Barack Obama.

Early efforts to establish a federally owned museum featuring African-American history and culture can be traced to 1915 and the National Memorial Association, although the modern push for such an organization did not begin until the 1970s. After years of little success, a legislative push began in 1988 that led to authorization of the museum in 2003. A site was selected in 2006, and a design submitted by Freelon Group/Adjaye Associates/Davis Brody Bond was chosen in 2009. Construction began in 2012 and the museum completed in 2016.
