The Flatiron Building at 175 5th Avenue, built in 1902, is one of the most recognizable landmarks in New York City. Set apart from its surroundings by its unique shape and presentation, the triangular 22-story building was one of the first buildings in New York City to utilize a steel frame when steel first became legal in construction. The steel allowed the building to be built much higher than most buildings at the time at 22 floors, making it one of New York’s earliest skyscrapers on top of being one of the city’s most unique looking. The Flatiron Building got its name from its resemblance to a clothes iron, and though its unusual shape caused controversy at the time of its erection, it is one of the most photographed buildings in the world. The triangular shape even creates unique strong wind currents that can be felt at the base of the buildings, some of the strongest in the city. The building currently houses publishing companies, though it is slotted to eventually become a hotel. This landmark building is definitely a must-see in NYC.
