Soldier Field in Chicago, Illinois, holds the official title of being the oldest stadium currently in use within the National Football League, having originally opened its doors in 1924. Although it initially served civic events and other athletic competitions before the Chicago Bears became permanent tenants in 1971, and underwent a massive interior renovation in 2003 that preserved its historic neoclassical exterior columns, it remains a landmark venue. Meanwhile, Lambeau Field in Green Bay stands as the oldest continuously operating stadium used by the same franchise since 1957.
