Man is said to have first built and controlled fire 100-thousand years ago. Ever since then, he has been building. To date, the oldest man-made structure-which has been scientifically vetted-is located in Greece. Specifically, the structure is a stone wall built approximately 23,000 years ago in front of a cave entrance. The cave is located in Theopetra, Greece, along the northern edge of the Thessalian Plain. Scientists believe the wall was built to avert wind during the Earth's most recent ice age.

The First Skyscraper   

Interestingly, the first skyscraper was NOT in New York, but built in Chicago in the years 1884 and 1885. Known as the world's first skyscraper, the Home Insurance Building was considered "gargantuan," rising ten stories into the air and topping-out at 138 feet above street level. Two stories were added later, making it a 12-story structure. It was considered the "Father-of-Skyscrapers" due to its unique design by structural engineer, Major William LeBaron Jenney.

Jenney designed a steel frame that supported the walls and the weight of the entire building. The exterior was a brick veneer. This building technique became known as "The Chicago Skeleton."

In an ironic twist, Chicago's Home Insurance Building was razed in 1931 at the tender age of 46. Meanwhile in 1931, New York City's Empire State Building was completed embodying 103 stories with a roof-height of 1,250 feet.

There is controversy as to when and where the first-ever multi-story parking garage appeared on the planet, so you can be the judge (information provided, below). In America; however, again we learn that Chicago was the first place for a structure of this type.

Approximately three blocks north of the Home Insurance Building is where the first multi-storied parking garage was built in 1918 to serve the guests at the luxurious and venerable Hotel LaSalle in the heart of Chicago. Designed by Holabird and Roche Architects, the garage featured five stories, above-ground parking with a spiral 10-foot-wide ramp that allowed automobiles to be parked on each level. While Chicago was the first city to build a parking garage, just a short 11 years later, America had more than 23 million cars on the road and American cities needed multi-storied parking garages.
