Treasures of New York: The Flatiron Building explores the lore of the iconic structure at 175 Fifth Avenue that has mesmerized the world for more than 100 years. Based on Alice Sparberg Alexiou’s book, “The Flatiron: The New York Landmark and the Incomparable City That Arose With It,” the documentary shares the stories behind the construction of the first skyscraper in Manhattan outside of the Wall Street area. Through rare, early motion pictures and photographs, the film takes viewers back to New York’s “Gilded Age” to show how the Flatiron Building became a singular expression of the exploding American metropolis. Additionally, it spotlights New York’s transformation into a modern city, its cultural heritage, points of interest, and notable figures at the time.
