The Hilton Washington DC National Mall The Wharf, previously known as the L'Enfant Plaza Hotel, is a 367-room hotel located on the top four floors of a 12-story mixed-use building in downtown Washington, D.C., in the United States. It was designed by architect Vlastimil Koubek, and was opened on May 31, 1973, as the Loews L'Enfant Plaza Hotel, named after Pierre Charles L'Enfant, the first surveyor and designer of the street layout of the city. The hotel sits atop L'Enfant Plaza, an esplanade and plaza structure erected above a highway and a parking garage in the Southwest quadrant of the District of Columbia. The plaza and hotel were approved in 1955, but construction did not begin on the plaza (on which the hotel sits) until 1965. The plaza and esplanade were completed in 1968. The start of construction on the hotel was delayed three years, and was completed in May 1973. The construction led to a lawsuit after it was found that the foundation of an adjoining structure had encroached on the hotel's property. The hotel suffered a serious fire in 1975 that claimed the lives of two people. L'Enfant Plaza Corp., which owned the hotel, sold the structure to Sarakreek Holdings in 1998, which in turn sold it to the JBG Companies in 2003. A legal battle ensued over the hotel's ownership. The hotel's original operator, Loews Hotels, was replaced after thirty-two years by Crestline Hotels & Resorts in 2005, which was in turn replaced by the Davidson Hotel Company in 2010. The hotel closed on December 3, 2013, for what was originally intended to be a year-long overhaul and upgrade of the entire property. It reopened on April 1, 2019, as the Hilton Washington DC National Mall.

L'Enfant Plaza is a complex of four commercial buildings grouped around a large plaza in the Southwest section of Washington, D.C., United States. Immediately below the plaza and the buildings is La Promenade shopping mall.The plaza is located south of Independence Avenue SW between 12th and 9th Streets SW (9th Street actually runs underneath the centers of the buildings on the easternmost side of the plaza). It was built perpendicular to L'Enfant Promenade, a north-south running street and pedestrian esplanade part of which is directly above 10th Street SW. The plaza is named for Pierre (Peter) Charles L'Enfant, the architect and planner who first designed a street layout for the capital city (see L'Enfant Plan). It was dedicated in 1968 after completion of the north and south buildings.

The Yellow House was the slave jail of the Williams brothers (Thomas Williams and William H. Williams), located at 7th Street and Maryland Avenue in Washington, D.C., the capital city of the United States. In 1838, William H. Williams directed people wishing to buy or sell slaves to his jail "on 7th street the first house south of the market bridge on the west side". The Williams' slave-trading business was apparently "large and well-known to traders in Richmond and New Orleans." The three-story building was made of brick covered in yellow-painted plaster and served as a navigation landmark for visitors to the city: "In an era before the memorials to Washington or Jefferson (much less the yet-unknown Lincoln) had been erected, D.C. travelers oriented themselves based on the Yellow House, which stood as a prominent landmark within the nation's capital." In 1843 a column in The Liberator referenced it: "If ever you have been to Washington you have probably noticed a large yellow house which stands about a mile from the avenue near the Potomac—That is the slave prison. It is owned by a celebrated slave trader, who has made a large fortune by following his hellish traffic. Slaves are not sold openly at public auction in this district so frequent as formerly. The traffic is carried on in secret. Thus public opinion begins to be felt even in the slave regions." There are at least two contemporary descriptions of the jail. One is from an account of attempting to rescue a man who had been kidnapped into slavery in 1848: Your old friend, Mr. ---- and myself started for the slave pen. The evening was not precisely cloudy, but the moon shone dimly through a smoky atmosphere. You know the building. It stands removed some distance from either road. As we approached, I could not but reflect that within its gloomy walls were yet retained all the horrid barbarity of the darker ages: yea, worse than this...Soon after we entered the yard, we met two men who appeared to be on patrole duty.— One of them turned round, and walked back to us, inquired if we wished to see Mr. Williams. We told him we did. He said Mr. Williams was not in, but his agent was. We told him we would then see the agent. As we came near the door, he told us to keep round to the left of him, as a large dog was chained in front of the door. Ascending the steps, he led us through a dark passage to a somewhat spacious room, having the appearance of an office. In front of a fire two men were sitting smoking cigars. He introduced us to one of them as the agent. To him we made known our errand. They both rose to their feet, and the agent said 'The negur has gone. We took him immediately on board ship at Alexandria, and he has sailed for New Orleans.' We told him the circumstances of his right to freedom. He assured us that it was not so—that 'the negur' told him he has not paid a cent. The building was deserted and derelict in 1853 when a news writer from Syracuse reported "I noticed that Williamson's [sic] slave pen had been dismantled, proparatory either to a removal or reconstruction of the building, it is situated in a lonely, though pleasant spot. An air of sorrow pervades it as though the groans, the sighs, and blood of its victims were still rising from its cells, and weighing down the atmosphere with their burden of grief." The Yellow House was located across from where the Hirshhorn Museum and Sculpture Garden stands today. The private prison was in use as a waystation of the interstate slave trade from 1836 to 1850. During his one term in the U.S. Congress, Abraham Lincoln recorded that he could see the building from the U.S. Capitol. A few years earlier, Solomon Northrup, a victim of kidnapping into slavery, could see the Capitol from his cell in the Williams' dungeon.

The Federal Aviation Administration (FAA) is a U.S. federal government agency within the U.S. Department of Transportation which regulates civil aviation in the United States and surrounding international waters.: 12, 16  Its powers include air traffic control, certification of personnel and aircraft, setting standards for airports, and protection of U.S. assets during the launch or re-entry of commercial space vehicles. Powers over neighboring international waters were delegated to the FAA by authority of the International Civil Aviation Organization. The FAA was created in August 1958 (1958-08) as the Federal Aviation Agency, replacing the Civil Aeronautics Administration (CAA). In 1967 the FAA became part of the newly formed U.S. Department of Transportation and was renamed the Federal Aviation Administration.

The Inner Loop was two planned freeways around downtown Washington, D.C. The innermost loop would have formed an oval centered on the White House, with a central freeway connecting the southern segment to the northern segment and then continuing on to Interstate 95. Interstate 95 would have met Interstate 66, Interstate 295, Interstate 695, and US 50 while traversing the Inner Loop. A second loop was an arc across the northern section of the city, beginning at East Capitol Street at the Anacostia River and using the Missouri Avenue NW and Nebraska Avenue NW commercial corridors to terminate in Georgetown.

Tiber Island also known as The Island was a man-made island in Washington, D.C. formed when the Washington City Canal was dug to connect the stream beds of Tiber Creek and James Creek, creating an island out of an existing peninsula southwest of the Capitol. The canals have since been filled in, rejoining the island to the mainland. The Southwest Waterfront, Buzzard Point, National Mall, and L'Enfant Plaza areas were once on the island; at that time, their isolation from "the mainland" led to the area's colloquial nickname as "The Island."The Tiber Island Cooperative Homes derive their name from the historic island.
