The Loop
Notable Building

A runt compared to today's tall buildings, this sparkling 19-story high-rise from Skidmore, Owings & Merrill was a trailblazer when it was built in the late 1950s. It was the first skyscraper erected with external supports (allowing for wide-open, unobstructed floors within), the first to employ steel pilings (driven 85 feet down to bedrock), the first in the Loop to be fully air-conditioned, and the first to feature underground parking.
