Federal Triangle

Murder Bay was a disreputable slum in Washington D.C. roughly bounded by Constitution Avenue NW, Pennsylvania Avenue NW, and 15th Street NW. The area was a center of crime through the early 20th century, with an extensive criminal underclass and prostitution occurring in several brothels and hotels in the area. The area was completely rebuilt during the construction of the Federal Triangle project in the late 1920s and 1930s.

The Ronald Reagan Building and International Trade Center, named after former United States President Ronald Reagan, is located in downtown Washington, D.C., and was the first federal building in Washington designed for both governmental and private sector purposes. Each of the organizations located in the Pennsylvania Avenue building is dedicated to international trade and globalization. Organizations headquartered in this building include U.S. Customs and Border Protection, U.S. Agency for International Development, and the Woodrow Wilson International Center for Scholars. The first private sector lease was signed with investment banking firm Quarterdeck Investment Partners, Inc. The building hosts conferences, trade shows, cultural events, and outdoor concerts. Post-9/11, security requirements for high-profile federal buildings have limited the amount of public/private access anticipated by the center's designers.

The National Children’s Museum is a children's museum and science center in downtown Washington, D.C. It is intended to serve children up to age 12 and their families through interactive exhibits exploring science, technology, engineering, art, and math. Founded in 1974, the Museum operated from 1979 to 2004 at 220 H Street, NE. It then operated as a “museum without walls,” until 2009, when it opened a new location in National Harbor, Maryland. That closed in 2015. A new location opened on February 24, 2020, in the Ronald Reagan Building in downtown Washington, before temporarily closing due to the COVID-19 pandemic. The Museum reopened on September 2, 2021. The Museum’s mission is to inspire children to care about and change the world. The Museum received a U.S. Congressional designation in 2003 when Congress identified a need for a nationally recognized cultural and educational institution specifically for children.

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.

The Oscar S. Straus Memorial in Washington, D.C., commemorates the accomplishments of the first Jew to serve in the cabinet of a U.S. president. Oscar Solomon Straus was Secretary of Commerce and Labor under President Theodore Roosevelt from 1906 to 1909. The memorial is a marble fountain located in the Federal Triangle on 14th Street between Pennsylvania Avenue and Constitution Avenue, Northwest, Washington, D.C. It is located in front of the Ronald Reagan Building and International Trade Center. The fountain was designed by Adolph Alexander Weinman, funded with a public subscription beginning in 1929, and dedicated on October 26, 1947. In the center of the memorial is the massive fountain with the inscription "statesman, author, diplomat" and to each side are two groups of statues, one called Justice (to symbolize the religious freedom which allowed a Jew to serve in such a position of authority) and the other Reason (to symbolize the capitalism and labor efforts put forth by Straus). It was rededicated on October 26, 1998.
