Scholars estimate that roughly 260,000 enslaved Africans -- about 40 percent of all those brought to North America -- passed through Charleston. A large number of them arrived at Gadsden's Wharf, a commercial dock on the Cooper River that served as the primary disembarkation point for human cargo during the 18th and early 19th centuries. For decades, the wharf's history lay buried under commercial development. When the city sold the waterfront parcel to a restaurateur, construction workers uncovered traces of the original wharf infrastructure. Former Charleston Mayor Joseph P. Riley Jr. recognized the significance immediately, repurchased the land, and began what would become a two-decade campaign to build a museum worthy of the site. Today, researchers estimate that 90 percent of African Americans can trace at least one ancestor to Charleston's port.

The museum's design by Henry N. Cobb of Pei Cobb Freed & Partners, in collaboration with Moody Nolan -- the largest African American-owned architectural firm in the United States -- treats the building as an act of interpretation. The elevated structure frames views across Charleston Harbor toward Fort Sumter and the open Atlantic, the same waters that carried the slave ships. Landscape architect Walter Hood designed the grounds beneath the museum as a contemplative garden, giving visitors a place to stand on the actual soil of Gadsden's Wharf. Inside, nine galleries hold more than 150 historical objects and 30 works of art across nearly a dozen interactive exhibitions. The museum does not merely catalog suffering; it traces the full sweep of African American experience, from the Middle Passage through enslavement, resistance, emancipation, and cultural achievement.

One of the museum's most powerful resources is its Center for Family History, a genealogical research hub that helps African Americans trace their ancestry through records that were deliberately scattered or destroyed during the era of enslavement. The center houses the largest collection of United States Colored Troops records outside the National Archives, along with more than 1,300 genealogy books, digitized slave ship manifests, and donated family photographs documenting Black neighborhoods and businesses across generations. iPad research stations provide access to 32 genealogy and African American historical databases. For many visitors, the center transforms the museum from an institution into something deeply personal -- a place where fragmented family histories can begin to reassemble.

Mayor Riley championed the museum as a public servant and then continued raising funds as a private citizen after leaving office. The $25 million private donation goal was met in 2018. Construction began in earnest, and the museum's first CEO, Michael B. Moore, guided the project through its development phase. The dedication ceremony in June 2023 drew a roster of speakers that reflected the museum's broad cultural significance: actress Phylicia Rashad, Congressman Jim Clyburn, gospel singer BeBe Winans, National Book Award-winning poet Nikky Finney, anthropologist Johnnetta Cole, and former NASA Administrator Charles Bolden. Within its first year, nearly 200,000 visitors walked through the doors. The museum had become not just a Charleston landmark but a national pilgrimage site.

From the museum's upper galleries, the view stretches across the Cooper River to the harbor and the Atlantic beyond. It is the same panorama that greeted those who arrived in chains -- the last horizon of a stolen journey. The IAAM does not look away from that history, but it also refuses to let the story end there. Its exhibitions celebrate the music, art, science, cuisine, and resilience that African Americans built from trauma and survival. Standing on the elevated walkways, visitors can look down through the open structure to the wharf ground below, then outward to the water, holding past and present in a single glance. The building was designed to make that dual vision unavoidable. It succeeds.
