While not the first sit-in of the Civil Rights Movement, the Greensboro sit-ins were an instrumental action, and also the most well-known sit-ins of the Civil Rights Movement.

Steven Tanger Center for the Performing Arts in downtown Greensboro, North Carolina is a $78.1 million 3,000-seat performing arts facility scheduled to open in 2019.  It will replace 2,400-seat War Memorial Auditorium in the Greensboro Coliseum Complex; the auditorium was torn down in October 2014.  The Community Foundation of Greater Greensboro raised $35 million privately, to be paid over ten years.  The city of Greensboro is paying $30 million.
