Why you should visit the Willis Tower.
The Willis Tower rises not just above Chicago, it defines it.
Once the tallest building in the world, this 110-story titan of steel and glass remains a global icon of human ambition and precision engineering. From the moment you step inside its grand lobby, there’s a palpable sense of reverence, the hum of elevators, the reflection of the skyline on obsidian glass, the quiet awareness that you’re inside a modern cathedral built for the sky. The tower embodies the boldness that shaped Chicago’s architectural legacy, a physical manifestation of the city’s creed: to reach higher, think bigger, and never stop reinventing itself. Its sheer verticality is humbling, but its artistry, the elegant bundled-tube design by Bruce Graham and Fazlur Rahman Khan, is what elevates it from skyscraper to masterpiece.
What you didn’t know about the Willis Tower.
When the Willis Tower (originally the Sears Tower) opened in 1973, it shattered every record, a mile of elevator cable, two million square feet of floor space, and an observation deck that seemed to touch the clouds.
But beyond its statistics lies an ingenious secret: the bundled-tube structure, composed of nine square tubes of varying heights, made it lighter, stronger, and more graceful than any tower before it. The design would go on to inspire skyscrapers worldwide, from Kuala Lumpur’s Petronas Towers to Dubai’s Burj Khalifa. Inside, the tower houses Skydeck Chicago, where visitors step onto The Ledge, a glass balcony suspended 1,353 feet in the air, for an unfiltered encounter with gravity and awe. Few realize that the tower sways up to six inches in strong wind, a motion so carefully engineered it feels imperceptible to those inside. What began as a corporate statement has become a civic monument, one that captures both the grit and the grace of the city that built it.
How to fold the Willis Tower into your trip.
Visit the Willis Tower in late afternoon for the full emotional spectrum, daylight clarity giving way to golden-hour glow.
Take the Skydeck elevator, which rockets 103 stories in just 60 seconds, and step out onto The Ledge for an experience that feels part thrill ride, part meditation. Watch the horizon stretch over Lake Michigan, the grid of Chicago unfurling beneath like an illuminated circuit board. Afterward, explore the newly renovated Catalog space at the tower’s base, filled with boutique dining, public art, and open-air terraces that reimagine the skyscraper’s ground level as a destination in itself. Stay until twilight, when the skyline turns molten and the tower’s dark form gleams like an exclamation point against the sky. You’ll leave understanding why Chicago doesn’t just build upward; it builds with purpose, style, and soul.
