The first image of the Tulsa skyline highlights the array of architectural styles featured in downtown Tulsa. The leftmost building, the Philtower, exhibits a combination of the Art Deco and Gothic Revival styles. The green roof of the mid continental building elegantly boasts Gothic Revival, while the First Place Tower to its right remains one of the tallest building in Oklahoma. The image to the right features the Tulsa Union Depot. Built in the 1930s, the Union Depot’s use of robust curves manifests the Streamline phase of Art Deco.
