Exhibits in this refurbished textile mill explore the state's natural history, archaeology, and historical development, as well as technological and artistic accomplishments. An iron gate made for the museum by Phillip Simmons, the "dean of Charleston blacksmiths," is on display, as is an exhibit on South Carolina's astronauts. In the Stringer Discovery Center, children can check out microorganisms under microscopes and climb inside a tree to observe the animals that live in the branches. Other objects include a reproduction of a Confederate submarine and artifacts associated with the state's cotton industry and slavery. Admission on the first Sunday of each month is only $1.
