One of the highest concentrations of Zigzag architecture in the United States resulted from a building boom in the early twentieth century, when Tulsa had become "the oil capital of the world". TULSA'S ZIGZAG STYLE, ART DECO ARCHITECTURE is a photographic exploration of what remains of the Art Deco Zigzag style in Tulsa. Many of the buildings have been demolished, some have collapsed, and many more have been remodeled. In 2010, the central part of downtown Tulsa was designated as the "Oil Capital Historic District". TULSA'S ZIGZAG STYLE, ART DECO ARCHITECTURE is a complete record of every Zigzag Art Deco building still standing in Tulsa, including which are on the official list of the National Register of Historic Places or designated a U.S. National Historic Landmark. This collection of images is the result of a yearlong project to capture the spirit of an era that combined the elegance of fine art with the practicality of industrial design and architecture.
