The decorative "Court of Honor" temporary columns erected on Fifth Avenue in front of the New York Public Library during the Hudson-Fulton Celebration in 1909 were designed by architect Ernest Flagg. Flagg was a prominent American architect known for his Beaux-Arts style, and he was commissioned to design these columns as part of the overall decorative scheme for the celebration. Ernest Flagg’s columns were classical in style, reflecting the neoclassical architectural trends of the time, and were intended to evoke a sense of grandeur and historical significance. These temporary structures added a sense of pageantry to the city, framing the public celebrations and the grand parades that took place along 5th Avenue.
