Taking visitors through the evolution of the cotton trader as well as its deep ties to slavery, this intense museum is inside the 1939 Memphis Cotton Exchange. Through photos and artifacts, you'll also learn the part Memphis's location along the Mississippi played in its growth, as well as how wealthy merchants and brokers downtown bought and sold the cotton that was loaded onto barges for shipment to the rest of the world. Allow yourself at least an hour—there are plenty of exhibits to explore, most of which are hands-on and interactive—including the 15-minute video you'll watch upon arrival.
