The White House Visitors Office is responsible for public tours of the White House, for maintaining a facility where the public can obtain information about the White House, and for other White House events such as the White House Easter Egg Roll, Holiday Open Houses, Spring and Fall Garden tours, State Arrival Ceremonies and other special events. The White House Visitor Center, which is managed and operated by the National Park Service, is located within President's Park at the north end of the Herbert C. Hoover Building (the Department of Commerce headquarters) between 14th Street and 15th Street on Pennsylvania Avenue NW, in the Federal Triangle. Since September 11, 2001, it no longer serves as a starting point for those going on a reserved tour of the White House. Instead, the various exhibits within it provide an alternative visitor experience for those not able to go on a tour. The themes of the six permanent exhibits are "First Families", "Symbols and Images", "White House Architecture", "White House Interiors", "Working White House", and "Ceremonies and Celebrations". Other exhibits change throughout the year. It houses a small bookstore operated by the White House Historical Association. The visitors office is located in the East Wing of the White House and employed seven people at the start of the 2000s. Its role has been unique in that, up to 2001, the White House was the only home of a head of state that was regularly open to the public at no cost. The director of the White House Visitors Office has been termed in media accounts as "the most powerful person in Washington that you've never heard of."

Fort Prince George was an uncompleted fort on what is now the site of Pittsburgh, at the confluence of the Allegheny and Monongahela Rivers in Allegheny County, Pennsylvania. The site was originally a trading post established by Ohio Company trader William Trent in the 1740s. Construction of Fort Prince George, named for the crown prince and later King George III), was begun in January 1754 by 41 Virginians. The plan to occupy the strategic forks was formed by Virginia Lieutenant Governor Robert Dinwiddie, on the advice of Lieutenant Colonel George Washington, whom Dinwiddie had sent on a mission to warn French commanders they were on English territory in late 1753, and had made a military assessment of the site. Captain Trent commanded the force constructing the fort, but his men were captured by 1,000 French soldiers and Indians led by Claude-Pierre Pécaudy de Contrecœur. At the time of the French arrival, Trent was at Wills Creek for a conference, while his second-in-command, Lieutenant John Fraser, was at his own plantation at Turtle Creek on the Mononghela River. Ensign Edward Ward was left to surrender the fort on April 18, 1754. The French attack was the hostile act of the war, and it led to George Washington's own surprise attack at the Battle of Jumonville Glen. Lieutenant Fraser was court-martialled for desertion at Williamsburg, but he was acquitted and later served as Chief of Scouts to General Edward Braddock's army. This was the first of five forts that would be built to control the strategic "Forks of the Ohio". The French erected Fort Duquesne after seizing Fort Prince George. Then the British built Fort Pitt after they captured the French post in the 1758 Forbes Expedition. Mercer's Fort was a temporary British fort built to defend against a French counterattack while Fort Pitt was being constructed. The final fort in what is now downtown Pittsburgh was an American post called Fort Lafayette and was located farther up the Allegheny River.

The National Capital Brewing Company was founded in 1890 by Albert Carry and Robert Portner, two successful Washington, D.C. area brewers. The brewery could produce 100,000 barrels of beer a year and was considered state-of-the-art for the time. It replaced a previous brewery which operated on the site since at least 1877.

The Alexander Dallas Bache Monument is the tomb of Alexander Dallas Bache, a noted American scientist and surveyor. Bache died in Newport, Rhode Island in 1867 and was transported to Washington, DC's Congressional Cemetery for burial. American architect Henry Hobson Richardson was commissioned to build a tomb in 1868. The tomb is one of only three examples of a monument designed by Richardson and a rare example of a Richardson structure lacking Romanesque design points.

The Global Methane Initiative (GMI) is a voluntary, international partnership that brings together national governments, private sector entities, development banks, NGOs and other interested stakeholders in a collaborative effort to reduce methane gas emissions and advance methane recovery and use as a clean energy source. National governments are encouraged to join GMI as Partner Countries, while other non-State organizations may join GMI's extensive Project Network. As a public-private initiative, GMI creates an international platform to build capacity, development methane abatement strategies, engage in technology transfer, and remove political and economic barriers to project development for emissions reduction. The initiative currently focuses on five sectors, which are known sources of anthropogenic methane emissions: agriculture, coal mining, municipal solid waste, municipal wastewater, and oil and gas systems.Through international cooperation, GMI seeks to reduce global methane emissions, the second largest contributor to atmospheric concentrations of greenhouse gases, in order to enhance economic growth, promote energy security, improve the environment, and reduce greenhouse gases. Other expected benefits include improving mine safety, reducing waste, and improving local air quality.

Eastern Methodist Cemetery, also known as Old Ebenezer Cemetery and Ebenezer Cemetery, was a 4-acre (16,000 m2) cemetery located in the Barney Circle neighborhood of Washington, D.C., in the United States. It was founded in 1824 as a privately owned Methodist cemetery open to the public. (The earliest interment at Eastern Methodist came before the cemetery was incorporated. That was Ely Drown, who was buried there on August 18, 1823.) Its owner was the Fourth Street Methodist Church at Ebenezer Station (hence the nickname "Ebenezer Cemetery"). The cemetery was located one a city block bounded by D, E, 17th, and 18th Streets NE. It was across the street from and north of Congressional Cemetery. The cemetery was designed to hold 1,830 burial plots. But because of the cemetery's popularity, there were multiple burials in each grave, and by the 1890s the cemetery held more than 3,000 bodies.During the roughly 70 years in which the cemetery was in operation, many of the leading citizens of the Barney Circle, Capitol Hill, Kingman Park, and Atlas District were buried at Eastern Methodist Cemetery. The cemetery was never in good financial condition, however. The price of burial plots was too low to permit the cemetery to establish a perpetual care fund.Eastern Methodist Cemetery was built on marshy ground, however, and it was not very suitable as a burial ground. About 1890, the cemetery's trustees proposed closing the cemetery. To finance the disinterral of remains, the cemetery would be subdivided and sold for building lots. Lotholders, however, rejected the proposal. The trustees then sought a legal solution. In 1891, Congress enacted legislation allowing Eastern Methodist Cemetery to remove all bodies in the cemetery and subdivide and sell the land to finance their reinterrment elsewhere. Some remains were claimed by family members. The Fourth Street Methodist Church agreed to disinter and box these remains, and reinter them at church expense at whatever local cemetery the family chose. Remains which went unclaimed were interred in mass graves at Congressional Cemetery. Although there initially was opposition among lotholders against the cemetery's closure, no lawsuit emerged.Disinterrals commenced at the cemetery on October 1, 1892. By October 4, about 50 bodies had been removed from Eastern Methodist Cemetery, and cemetery officials were predicting that the cemetery would be cleared by the end of the year. Cemetery officials said that they had located nearly every grave listed in the cemetery's lotbook, and full clearance of bodies from the grounds was almost certain. As of November 3, about 1,000 bodies remained to be unearthed, but officials said they were sure to have the work finished within three more weeks.

The Congressional Cemetery, officially Washington Parish Burial Ground, is a historic and active cemetery located at 1801 E Street, SE, in Washington, D.C., on the west bank of the Anacostia River. It is the only American "cemetery of national memory" founded before the Civil War. Over 65,000 individuals are buried or memorialized at the cemetery, including many who helped form the nation and the city of Washington in the early 19th century.Although the Episcopal Christ Church, Washington Parish owns the cemetery, the U.S. government has purchased 806 burial plots, which are administered by the Department of Veterans Affairs. Congress, located about a mile and a half (2.4 km) to the northwest, has greatly influenced the history of the cemetery. The cemetery still sells plots, and is an active burial ground. From the Washington Metro, the cemetery lies three blocks east of the Potomac Avenue station and two blocks south of the Stadium-Armory station. Many members of the U.S. Congress who died while Congress was in session are interred at Congressional Cemetery. Other burials include early landowners and speculators, the builders and architects of early Washington, Native American diplomats, Washington city mayors, and American Civil War veterans. Nineteenth-century Washington, D.C., families unaffiliated with the federal government also have graves and tombs at the cemetery. In all, there are one vice president, one Supreme Court justice, six Cabinet members, nineteen senators and seventy-one representatives (including a former speaker of the House) buried there, as well as veterans of every American war, and the first director of the Federal Bureau of Investigation, J. Edgar Hoover. The cemetery was listed on the National Register of Historic Places on June 23, 1969, and designated a National Historic Landmark in 2011.

This is a list of notable individuals who were buried at the Congressional Cemetery in Washington, D.C., as well as those who are memorialized by cenotaphs. In particular, many U.S. senators and U.S. representatives are memorialized by cenotaphs at the cemetery. Specialized terminology is used on this list. The term cenotaph includes not only monuments that are "empty tombs" or where the body is buried elsewhere, but also the graves of Congressmen who died in office which are marked by the particular style of cenotaph designed by Benjamin Latrobe for the Cemetery. "Congressman" refers to any U.S. senator or representative. A range/site listing, e.g. R31/S44, after a name gives the location of the grave or cenotaph according to the cemetery's location system.
