Skyscraper Day is celebrated annually on Sept. 3 to appreciate architectural marvels in the world while honoring the legendry architect John H. Sullivan who is also known as the "father of skyscrapers."

In 1885, William LeBaron Jenney designed the Home Insurance Building, the first skyscraper in Chicago. The building had 10 floors and used a curtain wall construction on a steel frame.

Sullivan was also called the "father of modernism" after he designed some of the famous buildings like the Wainwright Building, the Bayard-Condict Building, the Krause Music Store, the Union Trust Building and the Prudential (Guaranty) Building.

Today, skyscrapers are the most common site in any city skyline. You can celebrate Skyscraper Day by visiting your local skyscraper and spend time learning about the styles of architecture in your area. It is also a day to appreciate the efforts of engineers and architects who work hard to make these manmade wonders.
