In a corridor that tells the gruesome history of American slavery at this strikingly beautiful yet stark new museum, an embroidered sack tells a bitter history. In 1921, Ruth Middleton sewed her grandmother's story into the canvas, recounting how she was sold to another family at age nine, with only the sack containing a tattered dress, a few pecans, and a braid of her mother's hair to take with her. It's easy to see why the museum includes private reflecting rooms with tissues on hand. The IAAM relates a factual, vivid account of the Middle Passage from Africa to Charleston, where 40% of enslaved Africans entered America. But while acknowledging the gruesome past and societal disadvantages African Americans still face, the majority of the museum celebrates their achievements, from politics to music to visual art, including a flexible gallery space. Permanent exhibits include a reconstructed Gullah-Geechee prayer house, an authentic bateau used for fishing and shrimping in the Lowcountry, and an elaborate Mardi Gras Indian costume from New Orleans. Underneath the new waterfront museum is the city's newest and most evocative public space, including a path through a garden of sweetgrass and the Tide Tribute, a sculptural diagram of the floor of a slave ship that fills and empties with the shifting tide in Charleston Harbor.
