Explore the Historic Old Post Office in Chicago

Imagine stepping inside a building that’s over 90 years old, yet feels vibrantly alive thanks to a thoughtful restoration. That’s exactly what you get on the tour of Chicago’s Old Post Office, a striking example of early 20th-century architecture that’s been transformed into a modern, multi-use space. For just $15, you’ll spend about an hour and a half exploring this renovated landmark with a knowledgeable guide, learning about its history, architecture, and clever reuse.
This tour offers a rare chance to stroll through a building that once seemed destined for obscurity—vacant for nearly twenty years—and now gleams as a shining example of adaptive reuse. We love how the interior retains its historic charm while offering contemporary amenities, especially the roof-top meadow—a peaceful green space with city views that surprises many visitors. A minor consideration is that photography isn’t permitted inside, so you’ll want to focus on the details rather than snapping endless photos.

A Detailed Look at the Old Post Office Tour

Location and Accessibility
Starting at the iconic 433 W Van Buren Street, the tour is conveniently situated in downtown Chicago, with easy access via public transit. From the moment you arrive, you’re welcomed into a space that’s both historically significant and visually impressive. The building itself is a masterpiece of early 20th-century design, completed in 1934, and its recent renovation preserved many original details.
How the Tour Unfolds
The 90-minute walk-through begins with a visit to the Main Lobby, which many reviewers describe as “a marvel” that simply must be seen in person. As you stand beneath the soaring ceilings and admire the intricate architecture, your guide will share stories about the building’s original purpose and its decline before restoration.
One highlight is the “Zig-zag wall”, an eye-catching design feature that demonstrates the building’s historic craftsmanship. The “postcard wall” is another favorite, offering a visual journey through Chicago’s postal history with vintage images and artifacts. These elements show how a space designed for functional use can also serve as a canvas for storytelling.
The Renovation and Adaptive Reuse
The story of this building’s transformation is a key part of the tour. Once vacant for nearly 20 years, it became a symbol of urban renewal. The renovation involved converting the 2.8 million square foot structure into a modern office and event space, meeting the demands of today’s workforce while respecting its historic roots.
Guests will learn about the architectural challenge of preserving original details, like the grand lobby, while adding contemporary features such as the roof-top meadow—a 3.5-acre green space that’s become a favorite among visitors. This rooftop is a clear example of adaptive reuse at its best: turning a utilitarian postal building into a vibrant part of the city’s landscape.

Authenticity and Personal Touches
Our guide, “Lorie,” was praised for her engaging style and deep knowledge, making the history come alive. Many reviewers quote her as “spectacular,” noting how she used visual aids—maps, old photographs—to contextualize the building’s story. This personal touch makes the experience more meaningful, especially for history or architecture buffs.
What We Loved
Two features stood out for us. First, the interior details—from the ornate ceiling moldings to the vintage fixtures—show the building’s craftsmanship. Second, the rooftop meadow offers a surprisingly tranquil escape above the city streets, with views that are worth the climb.
Possible Drawbacks
The main limitation is that since this is an active commercial building, the itinerary might change without notice. Also, no photography is allowed inside, which might disappoint some who love snapping pictures of stunning architecture. Lastly, it’s a group tour with a maximum of 21 people, which is generally small, but during busy times, it could feel crowded.

The reviews confirm that guides like Lorie and Alice make the tour memorable, thanks to their knowledgeable, enthusiastic explanations.
