Standard Oil broke ground on former plantation land along the Mississippi River in 1909, and within a year Baton Rouge had a working refinery. The neighborhood that grew up next to it, built to house the plant's own workers, became known as Standard Heights. A century later, after decades of expansions, accidents, and a 2013 lawsuit over emissions, ExxonMobil bought out and demolished most of that same neighborhood -- not the plant, the people living next to it. A handful of residents are still there, refusing to leave.
