Tulsa is a city on the Arkansas River, in the U.S. state of Oklahoma. It’s known for its art deco architecture, mostly in the central Deco District. Landmarks like the Philcade and Philtower buildings reflect a 20th-century construction boom fueled by the prosperous local oil industry. The Philbrook Museum of Art is housed in an Italianate villa that was once the home of a local oil magnate.
Oklahoma City is the capital of the U.S. state of Oklahoma. It's known for its cowboy culture and capitol complex, surrounded by working oil wells. The reflecting pool, empty glass and bronze chairs of the Oklahoma City National Memorial recall the victims of the 1995 bombing of the Alfred P. Murrah Federal Building. The Survivor Tree, an American elm nearly destroyed in the attack, is also part of the memorial.
