Modeled after a 13th-century gothic cathedral in Chartres, France, the Riverside Church is an interracial, interdenominational and international church built in Morningside Heights by philanthropist John D. Rockefeller Jr. in 1927. The 2,400-member church has a rich tradition of providing a forum for important civic and spiritual leaders. Past speakers include Dr. Martin Luther King, Jr., Bill Clinton, the Dalai Lama, Fidel Castro, Archbishop Desmond Tutu and Nelson Mandela. The church plays host to music performances, including Sunday recitals of the Laura Spelman Rockefeller Memorial Carillon, several choirs and the Handbell Choir, plus theater performances at the Riverside Theatre. Tours of the church are also offered.
