Ask a local for directions to the Willis Tower and they might give you a blank stare—or a lecture.
Technically, the big black monolith with the twin antennas at 233 South Wacker Drive is called the Willis Tower. But in the hearts and GPS searches of millions, it’s still the Sears Tower. Whether you’re trying to find it for a Skydeck selfie or just trying to navigate the grid, knowing where is Sears Tower in Chicago is basically a rite of passage for anyone visiting the Windy City.
It sits right in the Loop, Chicago’s central business district. Specifically, it occupies a massive city block bounded by Franklin Street on the east, Wacker Drive on the west, Adams Street on the north, and Jackson Boulevard on the south. If you’re standing on the corner of Adams and Wacker, you’re looking up at one of the most significant engineering feats in human history.
Pinpointing the Location: Where Is Sears Tower in Chicago?
Basically, if you look toward the southwest corner of the Loop, you can't miss it. It’s the tallest thing there.

The tower is tucked right up against the Chicago River. This is actually pretty convenient if you’re doing the tourist rounds. You can hop off an architecture river cruise and walk to the tower's entrance in about three minutes. Honestly, the scale of the building is hard to grasp until you’re standing at its base on Wacker Drive, looking up at 1,450 feet of steel and glass.
Getting There Without Losing Your Mind
Chicago traffic is legendary for all the wrong reasons. If you're driving, be prepared to pay a premium for parking—think $40 or more for a few hours. Most savvy visitors use the "L" (Chicago’s elevated train system).
- Brown, Orange, Pink, or Purple Line: Get off at the Quincy station. It’s a two-block walk west. The station itself is vintage and cool, so it’s a win-win.
- Blue or Red Line: Exit at Jackson. You’ll have to walk a few blocks west toward the river.
- Metra (Commuter Rail): If you’re coming from the suburbs, both Union Station and Ogilvie Transportation Center are basically across the street. It’s arguably the most accessible skyscraper in the city for commuters.
The Name Debate: Why Is It Sometimes Called Willis?
In 2009, a London-based insurance broker named the Willis Group Holdings leased a chunk of space and secured the naming rights.
The city went into a collective meltdown.
People started petitions. There were "It’s the Sears Tower" Facebook groups with nearly 100,000 members. Even now, decades later, "Willis" feels like a dirty word to many Chicagoans. Sears, Roebuck & Co. commissioned the building in 1969 to house their 350,000 employees. Even though Sears moved out in the 90s, the name stuck like glue.

The naming rights agreement was for 15 years. Since we're now in 2026, the status of that name is a frequent topic of conversation in local bars. Blackstone, the current owner, has kept the Willis signage for now, but in Chicago, a name on a building is often just a suggestion.
Finding the Skydeck Entrance
Don’t just wander into the lobby at 233 South Wacker and expect to find the elevators to the top. The entrance for the Skydeck is actually located on the south side of the building along Jackson Boulevard.
You’ll descend into a lower-level museum area first. They’ve recently renovated this whole section—it’s now a multi-million dollar "Chicago experience" that’s actually pretty fun. You walk through a replica of a Chicago L car and learn about the city’s history before you even hit the elevators.
The Ledge: A Heart-Stopping Perspective
The main reason people look for the Sears Tower is The Ledge. These are glass boxes that extend 4.3 feet out from the 103rd floor.
- Height: 1,353 feet straight down.
- Visibility: On a clear day, you can see four states (Illinois, Indiana, Wisconsin, and Michigan).
- Safety: The glass is three layers thick. It’s solid. But your brain will still scream at you when you step onto it.
The "Bundled Tube" Secret
Why does the building look like a bunch of mismatched squares?
It wasn't just an aesthetic choice by architect Bruce Graham and structural engineer Fazlur Rahman Khan. It was a solution to the wind. Because Chicago is, well, the Windy City, a traditional square building of that height would sway too much.
They used a "bundled tube" system. Imagine nine separate square tubes bundled together at the base. As the building gets higher, the tubes drop off. Two drop off at the 50th floor, two more at the 66th, and three more at the 90th. Only two tubes go all the way to the 108th floor. This design makes the tower incredibly rigid, so it doesn't just look cool—it stays standing when the lake winds kick up to 60 mph.

Best Times to Visit for the Best Views
If you want the "Golden Hour" photos, aim for about 45 minutes before sunset.
However, everyone else has the same idea. To avoid the massive lines, go right when they open (usually 9:00 AM) or late at night. The city lights at 10:00 PM are arguably more impressive than the daytime view.
Pro Tip: If the weather looks "soupy" or foggy, check the live monitors at the ticket desk. There is nothing worse than paying for a ticket only to find yourself inside a very expensive cloud with zero visibility.
Actionable Steps for Your Visit
- Check the Weather: If the ceiling is below 2,000 feet, you won't see much. Use a weather app to check cloud height specifically.
- Book Online: Seriously. Do not try to buy tickets at the door unless you enjoy standing in line for two hours.
- Use the "L": Save yourself the $50 parking fee and take the Brown Line to Quincy.
- Eat Nearby: The building itself has a new "Catalog" dining area at the base with local spots like Brown Sugar Bakeries and Shake Shack. It's much better than the old-school vending machine vibes of the past.
- Look for the "S": Even though the Willis sign is everywhere, look for the subtle Sears-era details in the architecture. It's a fun scavenger hunt for history nerds.
The Sears Tower is more than just a pin on a map at 233 S Wacker Dr. It’s the anchor of the Chicago skyline. Whether you call it Sears or Willis, just make sure you look up—and if you’re brave enough, look straight down from the 103rd floor.
