Federal Triangle station

The William Jefferson Clinton Federal Building is a complex of several historic buildings located in the Federal Triangle in Washington, D.C., across 12th Street, NW from the Old Post Office. The complex now houses the headquarters of the Environmental Protection Agency (EPA). One component of the complex was originally called the New Post Office, and housed the headquarters of the Post Office Department until that department was replaced by the United States Postal Service in 1971 and which vacated the building. Subsequently, the Bureau of Alcohol, Tobacco, Firearms and Explosives (BATFE) occupied this building, which Congress renamed as the Ariel Rios Federal Building in 1985. BATFE vacated the building in the early 1990s, and EPA moved in after a renovation. To consolidate its headquarters offices, EPA also took occupancy of two adjacent buildings beginning in the late 1990s: the Interstate Commerce Commission (ICC) building and the Department of Labor Building, on Constitution Avenue, NW. In 2013 Congress renamed the Ariel Rios Federal Building in honor of former President Bill Clinton, and the General Services Administration extended the designation to the former ICC and Labor buildings. (The new BATFE headquarters building received the name Ariel Rios Federal Building in 2016.)

The Environmental Protection Agency (EPA) is an independent executive agency of the United States federal government tasked with environmental protection matters. President Richard Nixon proposed the establishment of EPA on July 9, 1970; it began operation on December 2, 1970, after Nixon signed an executive order. The order establishing the EPA was ratified by committee hearings in the House and Senate. The agency is led by its administrator, who is appointed by the president and approved by the Senate. The current administrator is Michael S. Regan. The EPA is not a Cabinet department, but the administrator is normally given cabinet rank. The EPA has its headquarters in Washington, D.C., regional offices for each of the agency's ten regions, and 27 laboratories. The agency conducts environmental assessment, research, and education. It has the responsibility of maintaining and enforcing national standards under a variety of environmental laws, in consultation with state, tribal, and local governments. It delegates some permitting, monitoring, and enforcement responsibility to U.S. states and the federally recognized tribes. EPA enforcement powers include fines, sanctions, and other measures. The agency also works with industries and all levels of government in a wide variety of voluntary pollution prevention programs and energy conservation efforts. In 2021, the agency had 14,297 employees. More than half of EPA's employees are engineers, scientists, and environmental protection specialists; other employees include legal, public affairs, financial, and information technologists. Many public health and environmental groups advocate for the agency and believe that it is creating a better world. Other critics believe that the agency commits government overreach by adding unnecessary regulations on business and property owners.

A statue in Carrara marble of Benjamin Franklin by Jacques Jouvenal stands outside the Old Post Office Pavilion, at 12th Street and Pennsylvania Avenue NW in Washington, D.C.

The Old Post Office, listed on the National Register of Historic Places as the Old Post Office and Clock Tower, is located at 1100 Pennsylvania Avenue, N.W. in Washington, D.C. It is a contributing property to the Pennsylvania Avenue National Historic Site.It succeeded an earlier 1839 edifice–the General Post Office–a building in the Classical Revival style, which was expanded in 1866 on F Street NW. This building later housed the Tariff Commission and several other agencies. The Old Post Office construction was begun in 1892 and completed in 1899. The building is an example of Richardsonian Romanesque, part of the Romanesque Revival architecture of the 19th-century United States. Its bell tower is the third tallest structure in Washington, excluding radio towers. It was used as the city's main General Post Office until 1914 at the beginning of World War I. Afterward, this Pennsylvania Avenue landmark structure functioned primarily as a federal office building. It was nearly torn down during the construction of the surrounding Federal Triangle complex in the 1920s and 1930s. In the 1970s, it was again threatened and nearly demolished to make way for the proposed completion of the enveloping Federal Triangle complex, the proposed buildings to be similar to the Beaux Arts-styled architecture of government offices built in the 1920s and 1930s. Major renovations to The Old Post Office Building were made in 1976 and 1983. The 1983 renovation opened a new chapter in the structure's history and use. Added to the structure were a food court, a retail space, and a roof skylight over the building's central atrium. The building acquired the name of "Old Post Office Pavilion." A glass-walled addition on a former adjacent parking lot was added to the structure in 1991. In 2013, the U.S. General Services Administration (GSA) leased the property for 60 years to a consortium headed by "DJT Holdings LLC", a holding company that Donald Trump owns through a revocable trust. Trump developed the property into a luxury hotel, the Trump International Hotel Washington, D.C., which opened in September 2016 and closed on May 11, 2022, after its sale to CGI Merchant Group. It reopened as the Waldorf Astoria Washington DC on June 1, 2022.The building's 315-foot (96-meter) high clock tower houses the "Bells of Congress," and its observation level offers panoramic views of the city and its surroundings.

The Woman Suffrage Procession on 3 March 1913 was the first suffragist parade in Washington, D.C. It was also the first large, organized march on Washington for political purposes. The procession was organized by the suffragists Alice Paul and Lucy Burns for the National American Woman Suffrage Association (NAWSA). Planning for the event began in Washington in December 1912. The parade's purpose, stated in its official program, was to "march in a spirit of protest against the present political organization of society, from which women are excluded." Participation numbers vary between 5,000 and 10,000 marchers. Suffragists and supporters marched down Pennsylvania Avenue on Monday, March 3, 1913, the day before President Woodrow Wilson's inauguration. Paul had selected the venue and date to maximize publicity, but met resistance from the D.C. police department. The demonstration consisted of a procession with floats, bands, and various groups representing women at home, in school, and in the workplace. At the Treasury Building, a pageant of allegorical tableaux was acted out during the parade. The final act was a rally at the Memorial Continental Hall with prominent speakers, including Anna Howard Shaw and Helen Keller. Prior to the event, the issue of black participation in the march threatened to cause a rift with delegations from Southern states. Some black people did march with state delegations. A group from Howard University participated in the parade. It is often said that black women were segregated at the back of the parade, however, contemporaneous sources confirm they marched with their respective state delegations or professional groups. During the procession, district police failed to keep the enormous crowd off the street, impeding the marchers' progress. Many participants were subjected to heckling from spectators, though there were also many supporters present. The marchers were finally assisted by citizens' groups and eventually the cavalry. The police were subjected to a congressional inquiry due to security failures. The event premiered Paul's campaign to refocus the suffrage movement on obtaining a national constitutional amendment for woman's suffrage. This was intended to put pressure on President Wilson to support an amendment, but he resisted their demands for years afterward. The procession was featured in the film Iron Jawed Angels in 2004. A new U.S. ten-dollar bill with parade imagery is planned for circulation in 2026.

The We the People March was a demonstration in Washington, D.C., in the United States, held on September 21, 2019. While the march had a broad mission statement, participants organized around a number of specific issues, including gun legislation and calls for the impeachment of President Donald Trump. The march was advertised as an event to remind elected officials that they work for the people, its organizer Amy Siskind saying that, "The members of Congress and especially (Speaker of the House) Nancy Pelosi need to feel the pressure to hold the Trump regime accountable. They have failed at that."The march drew thousands of protestors, including tennis player Martina Navratilova. The crowd marched down Pennsylvania Avenue from a starting point near the Trump International Hotel and ended at the U.S. Capitol. Siskind, who is well known for publishing The Weekly List, an online chronicle of what she calls the "not normal" events happening under the Trump administration, came up with the idea for the march over the summer after realizing that there was "a broad sense of frustration" among voters following the midterm elections in November 2018. She said that "I got the feeling that people wanted to do something. They wanted to take to the streets and march."The march took place just three days before House Speaker Nancy Pelosi announced the opening of an impeachment inquiry against Donald Trump.In addition to the march in Washington, D.C., 65 other solidarity marches took place on the same day across the country.

Federal Triangle is occupied by 10 large city and federal office buildings, all of which are part of the Pennsylvania Avenue National Historic Site. Seven of the buildings in Federal Triangle were built by the U.S. federal government in the early and mid-1930s as part of a coordinated construction plan that has been called "one of the greatest building projects ever undertaken" and all seven buildings are now designated as architecturally historic. The Federal Triangle Washington Metro station serves Federal Triangle and the surrounding area.

Murder Bay was a disreputable slum in Washington D.C. roughly bounded by Constitution Avenue NW, Pennsylvania Avenue NW, and 15th Street NW.
