One Block in Harlem

How important is it for African-American culture that Harlem remains what it has been since the 1920s - the undisputed capital of black America?

In the last decade the area has been going through dramatic changes.

First, former President Bill Clinton, opened his post-White House office there.

Then, as Manhattan real estate prices rocketed, wealthy people - many of them white - began moving in.

Michael Goldfarb traces this iconic neighbourhood's story by telling the history of a single street - 120th Street between 5th and 6th Avenues - from 1910, when it was a Jewish neighbourhood, to the present day.
