Near where I grew up there's a state prison called Angola, built in 1880 on the site of an old plantation called Angola. The slave quarters were repurposed as the original prisoner quarters. Mostly-black prisoners raise cotton and other crops for pennies on the hour, overseen by mostly-white officers called "freemen."
