The national memorial and museum will explore the history of lynchings, slavery, and racism in the US since the country's founding.
The six-acre site overlooks Montgomery.
The museum and memorial seek to create a dialogue around America's long history of racial injustice, EJI's founder, Bryan Stevenson, told Business Insider.
In the early 1860s, the US was at a turning point in its history. Following the election of Abraham Lincoln — a staunch opponent to slavery — 11 states led by the Confederacy announced they would secede.
Serving as the Confederate capital, Montgomery invited delegates from the Deep-South states to draft a constitution for a new nation in 1861. The Confederacy lost this fight, but Montgomery gained a nickname: the "Cradle of the Confederacy."
"Our nation’s history of racial injustice casts a shadow across the American landscape," he said. "This shadow cannot be lifted until we shine the light of truth on the destructive violence that shaped our nation, traumatized people of color, and compromised our commitment to the rule of law and to equal justice."

The memorial features 800 six-foot-tall metal blocks, which represent the 4,400 people who were killed by lynchings at the hands of white mobs between 1877 and 1950 in the US.
According to CNN, to find the names, Stevenson and a team of researchers went through court records and local newspapers — which often announced that a lynching was going to happen — and spoke to local historians and family members of victims.
When visitors go into the memorial, the blocks hang over their heads.
Each county has its own monument engraved with the names of the victims, along with the dates of their deaths.
Around the perimeter, there are matching, smaller plaques that EJI plans to give to each of the counties.

The 11,000-square-foot building is located on the site of a former warehouse where slaves were imprisoned after being taken to Montgomery.
The museum is also steps away from a dock and rail station where tens of thousands of black people were trafficked during the 19th century.
As part of EJI's Community Remembrance Project, the museum includes a display with jars of soil collected from lynching sites and engraved with the names of victims.
"We must address oppressive histories by helping communities to honestly and soberly recognize the pain of the past," the organization said.

In an interview with Business Insider, Montgomery Mayor Todd Strange said he doesn't plan to push for the removal of Confederate symbols in the city, including the name of Robert E. Lee High School, comprised predominantly of black students.
"I don't think taking them down changes history ... We don't go out and salute [the Confederate symbols] every day," he said. "The truth is I don't really think about it."
Montgomery became an icon of the Civil Rights Movement in the '50s and '60s, after activist Rosa Parks denied to give up her seat to a white passenger on a Montgomery bus in 1955, igniting a yearlong bus boycott in the city.
The Alabama State Capitol Building in Montgomery also served as the end point of the third and final march for voting rights from Selma, led by Dr. Martin Luther King Jr. in 1965.
Strange said it's important for Montgomery to not hide from its past so that communities can heal.
"By looking at the past, it's a reminder not to go back to those times," he said.
Usher, Common, The Roots, Kirk Franklin, and more will perform at the opening ceremony of the National Memorial for Peace and Justice and the Legacy Museum on April 26.
