Completed in 1897, the tomb is located in Riverside Park in the Morningside Heights neighborhood of Upper Manhattan in New York City, across Riverside Drive from the monumental Riverside Church.  It was placed under the management of the National Park Service in 1958. Riverside Drive is a scenic north-south thoroughfare in the Manhattan borough of New York City.  The boulevard runs on the Upper West Side of Manhattan, generally parallel to the Hudson River from 72nd Street to near the George Washington Bridge at 181st Street.  North of 96th Street, Riverside Drive is a wide divided boulevard; at other points it divides to provide a serpentine local street with access to the residential buildings.  Some of the most coveted addresses in New York are located along its route.

It is situated at 120th Street and 490 Riverside Drive, within the Columbia University Morningside Heights Campus, across the street from, and one block south of, President Grant's Tomb.  Although interdenominational, it is also associated with the American Baptist Churches USA and the United Church of Christ.  It is famous for its large size and elaborate Neo-Gothic architecture as well as its history of social justice.  It was described by "The New York Times" in 2008 as "a stronghold of activism and political debate throughout its 75-year history ... influential on the nation's religious and political landscapes."  It has been a focal point of global and national activism since its inception. William Sloane Coffin Jr. (June 1, 1924 – April 12, 2006) was an American Christian clergyman and long-time peace activist.  He was ordained in the Presbyterian church and later received ministerial standing in the United Church of Christ.  In his younger days he was an athlete, a talented pianist, a CIA agent, and later chaplain of Yale University, where the influence of Reinhold Niebuhr's social philosophy led him to become a leader in the Civil Rights Movement and peace movements of the 1960s and 1970s.  He also was a member of the secret society Skull and Bones.  He went on to serve as Senior Minister at the Riverside Church in New York City and President of SANE/Freeze (now Peace Action), the nation's largest peace and justice group, and prominently opposed United States military interventions in conflicts such as the Vietnam War to the Iraq War.  He was also an ardent supporter of gay rights. 55 Hudson Yards (also known as One Hudson Yards or One Hudson Boulevard) is a future tower just outside the Hudson Yards Redevelopment Project.

"Beyond Vietnam: A Time to Break Silence", also referred as Riverside Church speech, is an anti-Vietnam war and pro-social justice speech delivered by Martin Luther King Jr. on April 4, 1967, exactly one year before he was assassinated.  The major speech at Riverside Church in New York City, followed several interviews and several other public speeches in which King came out against the Vietnam War and the policies that created it.  Some, like civil rights leader Ralph Bunche, the NAACP, and the editorial page writers of the "Washington Post" and the "New York Times" called the Riverside Church speech a mistake on King's part.  Others—including James Bevel, King's partner and strategist in the Civil Rights Movement—called it King's most important speech.  It was written by activist and historian Vincent Harding. 3 Hudson Boulevard, previously tentatively known as the GiraSole, is a supertall skyscraper under construction in Manhattan's Hudson Yards and Hell's Kitchen neighborhoods along the Hudson Park and Boulevard in New York City.
