The Chatillon DeMenil House is a magnificent example of the late Greek Revival style in St. Louis, but its significance is more than architectural. The house embodies the stories of the families who lived here, including members of the founding families of St. Louis and Carondelet, a nationally known Western trailblazer, the family of an Oglala leader, the first chain drugstore operator in St. Louis, and a literary scholar who was a director of the 1904 World’s Fair.
