The Spirit Lives On

The Old Chicago Post Office was originally completed in 1921, but underwent a monumental expansion in 1932 to meet Chicago's unprecedented postal needs. The meteoric rise of the mail-order industry, spearheaded by the Chicago-based Montgomery Ward and Sears catalogs, transformed the city into the distribution center of the nation nearly overnight. In its postal heyday, the property was the largest of its kind in the world, capable of shuttling an astonishing 19 million pieces of mail daily. Though a lot has changed here since that time, that same spirit of raw ambition will live on in these walls for years to come.

Today, the property boasts over 2.5M SF of stunning multi-use office and event space, and is poised to once again become the central hub of Chicago's business community.
