St. Louis's history is layered. Each layer, whether the French pioneers establishing St. Louis as a river trading post, or Swiss immigrants starting dairy farms and dairies, or immigrants from Europe putting on the uniforms of the American doughboy, has left an imprint on the city. This Used to Be St. Louis is a fun trip through those layers of history following the story of: the glamorous, urban lofts that had been the factory for ball turrets for World War Two Air Force bombers; the dock of the pasta plant where the Civil War ironclads were built; the elegant townhouse that once served as a Albanian Orthodox Church.
