New York City is known for their towering skyscrapers that give power company executives—and tourists—a bird's eye view of the city. However, there is one building that stands tall at 29 stories—and doesn't have a single window. What a waste of a fantastic view!
33 Thomas Street is the location of the former AT&T Long Lines Building, built in 1974 and standing at 550 feet in the Manhattan Borough. It's a prime example of Brutalist architectural style, sporting no windows and existing as a flat concrete face—not too appealing on the eyes.
The main purpose of the building was to house telephone switching equipment with average floor heights of 18 feet, much larger than an average high-rise, and incredibly hard floors that can hold up to 200-300 pounds per square foot.
Six large air ducts protrude from the side of the building on the 10th and 29th floors—the only openings to the outside. Many consider it one of the most secure buildings in the world, able to withstand nuclear fallout for up to two weeks after a blast. It's also been noted as "the tallest blank wall in the world." Not exactly a prime tourist attraction.
