City Skylines Challenge – How Skylines Grew

Chicago and New York invented the skyscraper. Steel frames, safe passenger elevators and rising land prices in the late 1800s pushed buildings upward. The race for height peaked in 1930 and 1931, when the Chrysler Building and Empire State Building competed for the title.

Today skylines are city symbols. Seattle has the Space Needle, St. Louis the Gateway Arch and Las Vegas the Strat. Newer supertall towers, like Central Park Tower in New York, use concrete and dampers to stay steady in wind.
