Chicago Old Post Office Architecture Tour 90 min

Step inside a Chicago landmark transformed for modern life. On this 90-minute Chicago Old Post Office architecture tour, a certified Chicago Architecture Center docent reveals how a once-vacant building found a new purpose while preserving its remarkable character.

Completed in 1934, the 2.8-million-square-foot Old Post Office sat vacant for nearly two decades before a major renovation reimagined it as a contemporary office and event space. Walk through the building and spot historic artifacts and architectural details thoughtfully incorporated into its updated design. The tour also explores the conversion of the roof into a 3.5-acre urban park, a striking example of how an old structure can serve new needs.

Meet inside the Van Buren entrance. The building remains an active commercial space, so management may alter the itinerary without notice. Photography is not permitted. Join this Chicago Old Post Office architecture tour to see the landmark’s past and present come together in the heart of the city.
