National Skyscraper Day is observed every year on September 3 to appreciate the tallest habitable buildings. This day gives us an opportunity to appreciate the engineering and architectural marvels whose bold presence is in most cases overwhelming to the eyes. While the world’s first skyscraper was completed in 1885 in Chicago and it was only 138 feet (42 metres) tall, with just 10 storeys, in the current scenario, a building needs to have a minimum of 40 floors to be considered a skyscraper. On National Skyscraper Day 2022, let's take a look at the world’s seven tallest buildings. While some marvels are still under construction, these buildings mentioned are fully constructed and have been deemed the tallest as of April 2022. World Beard Day 2022: Date, History of The Designer Stubble, Significance and Everything About The Day That Celebrates The Ultimate Symbol of Manliness
