Once Abandoned, Grand Old Buildings Are Now At the Forefront of Modern Architecture
Photo by Gensler
Turn-of-the-century post offices in major urban centres are among America’s most architecturally significant buildings. But, as the postal industry waned with the advent of electronic communication, the remarkable buildings these institutions often inhabited were often vacated and abandoned.
Such was the case with the Old Chicago Post Office: The Beaux Art splendor was designed by Graham, Anderson, Probst & White. The original portion was completed in 1921 as a brick-side post terminal. By the time of a 1932 expansion that saw it grow to 2.8 million-square-feet, the new addition with a new INDIANA LIMESTONE™ clad exterior, it was America’s largest post office.

Celebrate Indiana Limestone Month With A Walking Tour of Chicago
We’re celebrating Indiana Limestone Month with a look at how this fine natural stone helped build much of Chicago’s storied skyline, and its role in turning the city into a top architectural destination.
Indiana Limestone’s place in Chicago’s history is a deep and durable one. Though it’s celebrated for its timelessness, it was a forward-thinking, future-minded move that helped create the link between limestone and the Windy City.

The White Granite That's Replacing Carrara Marble is Quarried in Vermont

The area around the north side was even sealed off after fears that the arch’s Italian Carrara marble exterior would fall on people below. The arch restoration team turned to hard-wearing Polycor BETHEL WHITEⓇ granite to replace the crumbling Carrara marble exterior and restore the arch to a place of pride.
