The irregular pentagonal site, one of the largest parcels assembled in lower Manhattan at that time, dictated the building’s distinctive shape. The powerful sculptural massing of the Standard Oil Building represents the new setback skyscraper forms that emerged during the early 1920s and suggests how tall buildings could be designed with vigorous massing and arresting silhouettes. The veneer-like limestone curtain walls are enriched with large-scale Renaissance ornamentation and reinforce the building’s picturesque quality, particularly at the upper stories.
