Oprah takes an emotional tour of new lynching victims memorial

On 60 Minutes, Oprah Winfrey toured The National Memorial for Peace and Justice in Montgomery, Alabama. The memorial is dedicated to the thousands of victims of racially motivated lynchings which occurred for more than 70 years after the Civil War.

The project was headed by civil rights attorney Bryan Stevenson. Stevenson and his team have chronicalled over 4,300 lynchings throughout the U.S. and have worked diligently to bring knowledge and closure to the victims' families.

The memorial itself is comprised of 805 steel markers, one for each county where lynchings took place. The names of the victims are inscribed on the markers,.

Each marker hangs from a single cable. They are designed to raise periodically as a reminder of the inhumanity and injustice of the lynchings. Oprah even commented that the brown rust on the steel is similar to the skin color of the victims.

Along with the memorial, Stevenson is also opening a museum documenting what he calls "the ugly parts" of American history, from enslavement to mass incarceration.

The 6 acre memorial will open to the public on April 26.
