Chicago is the architectural capital of the United States. It was the birthplace of the skyscraper, led so many architectural movements, and houses innumerable design masterpieces. "Chicago Architecture 101" on Heygo is a six-part series of 45-minute tours chronologically profiling the major architectural styles found downtown describing their influences and characteristics by showcasing beautiful buildings. All these styles build off of each other, so I hope you can see all six parts in the series. With all the tours in this series taking place after sunset, you'll get fantastic night-time views of the architecture and surrounding skyline.

"Mid-Century Modernism" is the fourth part of the six-part "Chicago Architecture 101" series. Between the Great Depression, World War II, and reconstruction, more than 20 years passed without a new skyscraper in Chicago. By the mid-1950s, the city was ready to add new towers, but a new style was needed to represent a more somber country as it looked to the future. Minimalist towers that were both simple and revolutionary emerged as Chicago became the Mid-Century Modern capital of the United States.
