Major General George B. McClellan is an equestrian statue in Washington, D.C. that honors politician and Civil War general George B. McClellan. The monument is sited on a prominent location in the Kalorama Triangle neighborhood due to efforts made by area residents. The statue was sculpted by American artist Frederick William MacMonnies, a graduate of the École des Beaux-Arts whose best known work is a statue of Nathan Hale in New York City. MacMonnies was chosen to design the statue following a lengthy competition organized by a statue commission, led by then Secretary of War William Howard Taft. The monument was dedicated in 1907, with prominent attendees at the ceremony including President Theodore Roosevelt, New York City mayor George B. McClellan, Jr., politicians, generals and thousands of military personnel. The sculpture is one of eighteen Civil War monuments in Washington, D.C., which were collectively listed on the National Register of Historic Places in 1978. The bronze statue, which rests on a tall granite base adorned with emblems and bronze reliefs, is surrounded by a small public park bounded by California Street, Columbia Road and Connecticut Avenue NW. The monument and park are owned and maintained by the National Park Service, a federal agency of the Interior Department.

The Washington Hilton is a hotel in Washington, D.C. It is located at 1919 Connecticut Avenue, N.W., roughly at the boundaries of the Kalorama, Dupont Circle, and Adams Morgan neighborhoods. The Washington Hilton, located on the former site of the Oak Lawn estate, was designed by architect William B. Tabler and developed by Uris Buildings Corporation. A groundbreaking ceremony was held on June 25, 1962 and the hotel officially opened three years later, on March 25, 1965. The hotel structure features a distinctive double-arched design. It long sported the largest pillar-less hotel ballroom in the city. Numerous large events have been regularly hosted at the Hilton Washington, including the annual dinners of the White House Correspondents Association and the Radio and Television Correspondents Association, as well as the National Prayer Breakfast. During the 1960s and 1970s, the hotel hosted a number of big musical acts for concerts in their large ballroom, including The Doors and Jimi Hendrix. In 1972 it was home to the first International Conference on Computer Communications which demonstrated new ARPANET technology. The hotel was the site of the assassination attempt on President Ronald Reagan by John Hinckley Jr. on March 30, 1981. The attempt occurred at the hotel's T Street NW exit. As a result, the hotel is sometimes colloquially referred to by locals as the "Hinckley Hilton".The hotel was renamed the Hilton Washington in 1998. It was purchased in June 2007 by an investment firm jointly owned by former professional basketball star Magic Johnson. From 2009-2010 it underwent a $150 million renovation. When that was completed, the hotel returned to its original name.

Crystal Heights (also referred to as Crystal City) was a design by American architect Frank Lloyd Wright for a hotel, apartment, and shopping complex in Washington, D.C. The project would have been built on one of the largest remaining undeveloped tracts in the city, known as the Oak Lawn estate or Temple Heights, on the edge of the Adams Morgan and Dupont Circle neighborhoods. The site was bounded by 19th Street, Columbia Road, Connecticut Avenue, and Florida Avenue, all in the northwest quadrant. One version of the design called for 2,500 hotel rooms, small apartments, parking for 1,500 cars, shops, and a 1,000-seat theater – a diversity of uses almost never seen in structures of the time – all within a complex consisting of a broad base covering the whole site topped by 15 towers. The proposal was defeated primarily by zoning requirements that prevented a multi-purpose structure at the site and forbade towers from rising more than 110 feet. The planned central tower would have been 240 feet high (73 m) and the remaining buildings 14-stories tall. After his design was rejected, Wright heavily criticized local officials and the National Capital Planning Commission. Today, the site is occupied by the Washington Hilton, commercial buildings, and an apartment building.

On March 30, 1981, United States president Ronald Reagan was shot and wounded by John Hinckley Jr. in Washington, D.C. as he was returning to his limousine after a speaking engagement at the Washington Hilton. Hinckley believed the attack would impress actress Jodie Foster, with whom he had developed an erotomaniac obsession. Reagan was seriously wounded by a .22 Long Rifle bullet that ricocheted off the side of the presidential limousine and hit him in the left underarm, breaking a rib, puncturing a lung, and causing serious internal bleeding. He was close to death upon arrival at George Washington University Hospital but was stabilized in the emergency room, then underwent emergency exploratory surgery. He recovered and was released from the hospital on April 11. No formal invocation of sections #3 or #4 of the Constitution's 25th amendment (concerning the vice president assuming the president's powers and duties) took place, though Secretary of State Alexander Haig stated that he was "in control here" at the White House until Vice President George H. W. Bush returned to Washington from Fort Worth, Texas. White House press secretary James Brady, Secret Service agent Tim McCarthy, and DC police officer Thomas Delahanty were also wounded. All three survived, but Brady suffered brain damage and was permanently disabled. His death in 2014 was considered a homicide because it was ultimately caused by his injury.Hinckley was found not guilty by reason of insanity on charges of attempting to assassinate the president. He remained confined to St. Elizabeth's Hospital, a DC psychiatric facility. In January 2015, federal prosecutors announced that they would not charge Hinckley with Brady's death, despite the medical examiner's classification of his death as a homicide. Hinckley was released from institutional psychiatric care on September 10, 2016.

Oak Lawn (later known as the Dean Estate, Temple Heights, and Temple Hill) was a large house and wooded estate that once stood on the edge of today's Dupont Circle and Adams Morgan neighborhoods in Washington, D.C. The estate was bounded by 19th Street, Columbia Road, Connecticut Avenue, and Florida Avenue. Previously called Widow's Mite, the estate was originally several hundred acres, but by the 19th century, had been reduced to around 10 acres (4 ha). The house was built around 1820 and was greatly expanded in 1873 by Thomas P. Morgan, one half of the eponym of the Adams Morgan neighborhood. A large oak tree, nicknamed the Treaty Oak, was reportedly hundreds of years old and stood just a few yards from the house. Oak Lawn was located on a hill. Due to its expansive views of the city, the estate was sought after by local developers. The surrounding neighborhoods evolved into bustling residential and commercial areas. However, Oak Lawn remained a wooded, undeveloped tract until the 20th century. In 1922 the land was sold to a Masonic group who wanted to build a large temple complex. However, due to the Great Depression and a lack of funds, the plan was canceled. In 1940, a local developer selected Frank Lloyd Wright to design a massive mixed-use project there (Crystal Heights) that would include 14 towers and a hotel: that project was also canceled. During the next 20 years, multiple plans for Oak Lawn never came to fulfillment. The Oak Lawn house was demolished in 1948, and the Treaty Oak cut down in 1953. In the late 1950s and early 1960s, the Washington Hilton and two commercial buildings were built on the property that had been home to the old estate.

The Treaty Oak was a 350–400-year-old oak tree that once stood on the Oak Lawn estate in Washington, D.C. The estate was previously called Widow's Mite and owned by the Holmead and Nourse families. It included a large four-story Second Empire house that owner Thomas P. Morgan had expanded. The estate was bounded by 19th Street, Columbia Road, Connecticut Avenue, and Florida Avenue, on the edge of today's Dupont Circle and Adams Morgan neighborhoods. The oak tree earned its nickname due to local legends that a treaty was signed there between early settlers and Native Americans. Despite massive development in the surrounding neighborhoods during the late 19th century and early 20th century, the estate remained a wooded area and was sought by local developers. In 1922 a Masonic group purchased the estate for what was then a significant amount of money to build a massive complex that would include temples. The plans were never carried out, and in 1940 the site was chosen for the large Crystal Heights mixed development designed by Frank Lloyd Wright. That plan was also abandoned. The tree remained until 1953 when it was felled for a planned commercial development. The land where the tree and house once stood is the site of the Washington Hilton, an apartment building, and two office buildings. At the time of its destruction, the Treaty Oak was reportedly the largest oak tree in the Washington, D.C. area.
