The Capitol Reflecting Pool is a reflecting pool in Washington, D.C., United States. It lies to the west of the United States Capitol and is the westernmost element of the Capitol grounds (or the easternmost element of the National Mall, according to some reckonings). The Capitol Dome and the Ulysses S. Grant Memorial are reflected in its waters.

Purple Tunnel of Doom was the name ascribed to the I-395 Third Street tunnel in downtown Washington, D.C., where thousands of holders of purple tickets lined up to witness the first inauguration of Barack Obama on January 20, 2009. Ticket colors corresponded to assigned viewing areas. Many were not admitted, despite having stood in line for hours.

The Ulysses S. Grant Memorial is a presidential memorial in Washington, D.C., honoring American Civil War general and 18th United States President Ulysses S. Grant. It sits at the base of Capitol Hill (Union Square, the Mall, 1st Street, between Pennsylvania Avenue and Maryland Avenue), below the west front of the United States Capitol. Its central sculpture of Grant on horseback faces west, overlooking the Capitol Reflecting Pool and facing toward the Lincoln Memorial, which honors Grant's wartime president, Abraham Lincoln. Grant's statue is raised on a pedestal decorated with bronze reliefs of the infantry; flanking pedestals hold statues of protective lions and bronze representations of the Union cavalry and artillery. The whole is connected with marble covered platforms, balustrades, and stairs. The Grant and Lincoln memorials define the eastern and western ends, respectively, of the National Mall. The Grant Memorial is a contributor to the Civil War Monuments in Washington, D.C., of the National Register of Historic Places. James M. Goode's authoritative The Grant Memorial in Washington, D.C. (1974) called it "one of the most important sculptures in Washington." It includes the largest equestrian statue in the United States and the fifth-largest in the world.

It is a monument to the naval deaths during the American Civil War. The monument is topped by the allegorical sculptures of Grief and History. On the southeast side facing the United States Capitol there is a figure of Peace, and on the northwest side, there are figures of Victory and the babies Mars and Neptune.

The James A. Garfield Monument stands on the grounds of the United States Capitol in the circle at First Street, S.W., and Maryland Avenue, Washington, D.C. It is a memorial to United States President James A. Garfield, elected in 1880 and assassinated in 1881 after serving only four months of his term, by a disgruntled office-seeker named Charles J. Guiteau. The monument, sculpted by John Quincy Adams Ward (1830–1910) and cast by The Henry-Bonnard Co. of New York, with a pedestal designed by Richard Morris Hunt, is an outstanding example of American Beaux-Arts monument. It was unveiled on May 12, 1887. Today it stands as part of a three-part sculptural group near the Capitol Reflecting Pool including the Peace Monument and the Ulysses S. Grant Memorial. The memorial was commissioned in 1884 by the Society of the Army of the Cumberland, of which Garfield had been a member. The Society raised almost $28,000 to pay the sculptor. Some of the funds were raised by The Garfield Monument Fair, which was held in the Capitol's Rotunda and National Statuary Hall in 1882. Also in that year, Congress appropriated to the Society $7,500 in funds from the sale of condemned cannons; in 1884 it appropriated $30,000 for the pedestal. The monument was incorporated into the Capitol Grounds on January 2, 1975.

The Capitol Christmas Tree (formerly the Capitol Holiday Tree) is the decorated tree that is erected annually on the West Front Lawn of the United States Capitol, in Washington, D.C., to celebrate the Christmas holiday season. The selection, installation, and decoration of the tree are all overseen by the Superintendent of the Capitol Grounds of the Architect of the Capitol (AOC). The tree is traditionally lit by the Speaker of the United States House of Representatives, joined by a essay contest winner during a ceremony at the beginning of December, and remains lit each night through New Year's Day. By tradition, the President and Vice President of the United States will not attend the tree lighting ceremony.

Capitol Hill, in addition to being a metonym for the United States Congress, is the largest historic residential neighborhood in Washington, D.C., stretching easterly in front of the United States Capitol along wide avenues. It is one of the oldest residential neighborhoods in Washington, D.C., and, with roughly 35,000 people in just under 2 square miles (5 km2), it is also one of the most densely populated.As a geographic feature, Capitol Hill rises near the center of the District of Columbia and extends eastward. Pierre (Peter) Charles L'Enfant, as he began to develop his plan for the new federal capital city in 1791, chose to locate the "Congress House" (the Capitol building) on the crest of the hill at a site that he characterized as a "pedestal waiting for a monument." The Capitol building has been the home of the Congress of the United States and the workplace of many residents of the Capitol Hill neighborhood since 1800. The Capitol Hill neighborhood today straddles two quadrants of the city, Southeast and Northeast. A large portion of the neighborhood is now designated as the Capitol Hill Historic District. The name Capitol Hill is often used to refer to both the historic district and to the larger neighborhood around it. To the east of Capitol Hill lies the Anacostia River, to the north is the H Street corridor, to the south are the Southeast/Southwest Freeway and the Washington Navy Yard, and to the west are the National Mall and the city's central business district. The Capitol building is surrounded by the Capitol Hill Historic District, which is listed on the National Register of Historic Places (NRHP). The Capitol Hill Historic District was expanded in 2015 to the north to include the blocks bordered by 2nd Street, F Street, 4th Street, and just south of H Street, NE, collectively known as the Swampoodle Addition.

On January 6, 2021, Ashli Babbitt was fatally shot during an attack on the United States Capitol. She was part of a crowd of supporters of U.S. President Donald Trump who breached the United States Capitol building seeking to overturn his defeat in the 2020 presidential election. Babbitt attempted to climb through a shattered window beside a barricaded door into the Speaker's Lobby, and was subsequently shot in the left shoulder by a United States Capitol Police (USCP) officer. After a USCP emergency response team administered aid, Babbitt was transported to Washington Hospital Center, where she later died. The USCP deemed the shooting was "lawful and within Department policy" and "potentially saved Members (of Congress) and staff from serious injury and possible death".

Mary Ann Hall (1814 or 1815 – January 29, 1886) ran a successful brothel from the 1840s until about 1878 at 349 Maryland Avenue SW, Washington, D.C., about four blocks west of the U.S. Capitol. Before the National Museum of the American Indian was built on the site in 1999, the Smithsonian Institution conducted an archeological excavation of the foundations and garbage dump of the house. The expensive tableware in the garbage dump was made of ironstone and porcelain. Food remnants include meat, fowl, fish, and exotic fruits like coconuts and berries. French champagne corks were especially numerous. She built a three-story house on the site which rose greatly in value. Her business was apparently very successful and she died with a net worth of $87,000 - worth over $2,000,000 in 2005 dollars.In 1864 the Union Army's Provost Marshal published a list of brothels in Washington and Mary Ann Hall's had 18 "inmates," making it the largest in the city.She was buried with her sister and other family members under "large and dignified" memorials at the Congressional Cemetery in Washington, D.C.Her summer home in Arlington was later owned by Presley Marion Rixey and is now Marymount University.
