Sweet Auburn is Atlanta's historic African-American neighborhood—it also houses The King Center, established by Dr. Martin Luther King, Jr.'s late wife Coretta, and was where the civil rights activist was born—so it makes sense this district would be home to the APEX Museum, whose motto is "Where Every Month is Black History Month." The museum covers quite a lengthy time span, starting in ancient African civilizations and ending at the present day. Exhibits chronicle slavery, the neighborhood's evolution, and, of course, the Civil Rights Era. Recent traveling installations have featured black inventors and African-American pioneers in the space program. In the permanent exhibitions, visitors will find replicas from Sweet Auburn icons like the Yates and Milton Drugstore—which not only employed African-Americans, but became a hangout for the black community. In the Trolley Theater, you can sit inside a replica of the old trolley that ran up and down Auburn Avenue as you watch a multimedia presentation about the area's history. As it's on the smaller side, you can explore the museum in less than 1 hr. On your way out, drop in on the historic Herndon Plaza across the street to see rotating exhibits of African-American works, as well as the permanent collection of the Herndon family.
