In addition, the equestrian statue of General Philip Sheridan is 1 of 18 Civil War Monuments in Washington, D.C., that were collectively listed on the NRHP.

Some of the embassies and ambassadorial residences facing Sheridan Circle include Romania, Ireland, Greece, Vietnam, Kenya, Egypt, South Korea, Latvia, and Turkey.

Two violent moments that occurred at Sheridan Circle were the assassination of Orlando Letelier and Ronni Karpen Moffitt by Chile's Dirección de Inteligencia Nacional.

The other violent moment took place in 2017 when clashes broke out between the Kurdistan Workers' Party (PKK) supporters and Kurdish separatists who were protesting Turkish President Recep Tayyip Erdoğan.

[3] The area that now encompasses Sheridan Circle, and much of the present-day Sheridan-Kalorama neighborhood, were originally large estates built outside the city's boundary.

[2][5] The large residences built along Massachusetts Avenue were designed by prominent architects from Washington, D.C., as well as ones from other major cities.

Michael Townley, a DINA U.S. expatriate among those convicted for the crime, confessed that he had hired five anti-Castro Cuban exiles to booby-trap Letelier's car.

According to Jean-Guy Allard, after consultations with the Coordination of United Revolutionary Organizations leadership (including Luis Posada Carriles and Orlando Bosch), those selected to carry out the murder were Cuban Americans José Dionisio Suárez, Virgilio Paz Romero, Alvin Ross Díaz, and brothers Guillermo and Ignacio Novo Sampoll.

[10][11] According to news reports, Luis Posada Carriles was at the meeting that decided on Letelier's death and also about the Cubana bombing two weeks later.

[10] Letelier and Moffitt are commemorated with a small plaque embedded in the grass along the curb where they died, near the Irish and Romanian embassies.

[12] On May 16, 2017, dozens of Kurdistan Workers' Party (PKK) supporters and Kurdish separatists clashed with Turkish security officials at Sheridan Circle.

[13] Turkish President Recep Tayyip Erdoğan, visiting the ambassadorial residence on the circle, watched the clashes from a distance.

[14] During a civil suit by some of the PKK supporters against the Turkish government, a U.S. judge denied Turkey's citing the Foreign Sovereign Immunities Act as to why the case should be dismissed.
