You’ve seen it. Even if you have never stepped foot in Ohio, you know that sweeping, semi-circular limestone facade. It’s the towering home of the Super Friends. It is where Superman, Wonder Woman, and Batman gathered to monitor global threats. But in the real world, it’s not in a fictional metropolis. It’s sitting right on Western Avenue in Cincinnati. The Hall of Justice Union Terminal connection isn’t just a fun piece of trivia for comic book nerds; it is a bizarre intersection of high-concept Art Deco architecture and Saturday morning cartoon history.
Honestly, the building is more impressive in person than it ever was in the 1970s animation.
Cincinnati Union Terminal opened in 1933. It was a "temple of transportation." By the time the Super Friends cartoon premiered in 1973, the station was actually struggling to survive. While the Justice League was "saving the world" from their headquarters, the real-life inspiration was nearly facing the wrecking ball. It’s a weird bit of irony.
The Animation Origin: How a Train Station Became a Superhero Base
How did a Midwestern train station become the headquarters for the world's most powerful beings? It wasn't a random accident. Al Gmuer, a background supervisor for Hanna-Barbera, was the man responsible for the design.
He needed something that looked "heroic" but also futuristic.
Gmuer reportedly sketched a few designs that didn't quite hit the mark. Then, he looked at the Cincinnati Union Terminal. Its massive half-dome—the largest in the Western Hemisphere at the time—and its clean, vertical lines screamed "authority." It looked like a place where important things happened. He simplified the windows, added some heroic flair, and the Hall of Justice Union Terminal link was born.
Surprisingly, Gmuer wasn't even from Cincinnati. He just knew a good silhouette when he saw one.
The cartoon version omitted the massive wings of the building that housed the train platforms. Instead, it focused on that iconic rotunda. In the show, the interior was all glowing screens and computers. In reality, the interior of Union Terminal is covered in massive, breathtaking mosaics by Winold Reiss. These murals depict the history of American industry and the settling of the Ohio River Valley. It’s a different kind of heroism.

Architecture That Defies Time
People call it Art Deco, but specifically, it’s "French Art Deco" or "Zigzag Moderne." It was designed by the firm Fellheimer & Wagner. They didn't just want a station; they wanted a statement.
The scale is hard to process until you are standing under the dome. The rotunda spans 180 feet. It’s 106 feet high.
- The limestone is Indiana-sourced.
- The terrace fountains are meant to mimic the flow of the Ohio River.
- The acoustics are legendary; there are "whispering fountains" where you can sit at one end of a curved wall, whisper, and a person at the other end hears you perfectly.
Imagine the Justice League using that to trade secrets. It's basically a low-tech intercom.
During World War II, this place was a beehive. It saw 34,000 people pass through every single day. Soldiers, families, travelers—everyone moved through the rotunda. But by the late 1960s, the rise of the automobile and air travel killed the passenger rail business. The station became a ghost town. When the Super Friends was being drawn, the real building was being partitioned off. There was even a short-lived, failed shopping mall inside it during the 1980s.
The DC Comics Legacy and the Arrowverse
For decades, the Hall of Justice was just something fans "knew" was based on Cincinnati. But DC Comics eventually leaned into it. In the comics, they officially established that the Hall of Justice was located in Washington, D.C., but they kept the Union Terminal aesthetic.
Then came the CW's Arrowverse crossover event, "Invasion!"
In 2016, the producers needed a location for the heroes to meet. They used a digital composite of the Cincinnati Union Terminal for the exterior shots. Seeing the Flash, Supergirl, and Green Arrow standing in front of a building that looked exactly like the Cincinnati landmark sent fans into a frenzy. It was a full-circle moment. The building wasn't just an inspiration anymore; it was the literal setting.

A $228 Million Resurrection
If you visit today, you aren't seeing a decaying relic. You’re seeing a miracle of historic preservation. Between 2016 and 2018, the building underwent a massive renovation. It cost roughly $228 million.
They had to clean every single piece of that limestone. They repaired the Winold Reiss mosaics. They fixed the structural issues that were literally causing the building to crumble. Now, it houses the Cincinnati Museum Center. You can go in there and see a dinosaur gallery, an OmniMax theater, and a children's museum.
It’s busy again. The energy has returned.
One of the most fascinating things about the Hall of Justice Union Terminal connection is how it changed the way people view the building. Kids don't just see a museum; they see the place where Batman works. The building has transitioned from a functional transport hub to a cultural icon, and then to a piece of pop-culture mythology.
Why the Design Actually Works for Superheroes
There is a psychological reason the Hall of Justice feels "right" as a hero base. The Art Deco movement was about progress. It was about the future. It used bold lines and symmetrical shapes to convey stability and power.
When you look at the building, you feel safe.
It doesn't look like a dark, brooding cave. It looks like a beacon. The light reflects off the limestone and the glass windows of the rotunda, making it glow during the day. In the Super Friends cartoon, they usually drew it with a bright blue sky behind it. That wasn't just for color—it was for the vibe. It symbolized a "brightest day" philosophy that defined that era of superheroes.

Misconceptions About the Location
A lot of people think the Hall of Justice is just a nickname locals gave the building. That’s not true. It’s a recognized historical fact within the industry. Others think the building was built to look like the cartoon. Obviously, the timeline is backwards. The station was there 40 years before the cartoon existed.
There's also a myth that there are secret underground tunnels leading all the way to downtown Cincinnati. While there are old utility tunnels and baggage paths, they aren't some vast "Batcave" network. They were mostly for moving mail and luggage between trains.
Still, the sheer size of the basement levels is enough to make you wonder.
How to Visit and What to Look For
If you are a fan of the show or a lover of architecture, you have to go. It’s located at 1301 Western Avenue. Parking is easy, but the real thrill is the approach. Driving up the long driveway toward the rotunda is the closest you’ll ever get to being a member of the Justice League.
Pro-tips for your visit:
- Check the Fountains: They only run during the warmer months, but the cascading water is essential for that "heroic" photo op.
- Look at the Mural Details: In the rotunda, look for the figures in the mosaics. They represent the people who built America. It’s incredibly detailed work using tiny glass tiles.
- Visit the Library: There is a history library on the upper floors that feels like a secret archive.
- Stand in the Center: Stand right in the middle of the rotunda and look up. The scale is dizzying.
The Hall of Justice Union Terminal is one of those rare cases where the real-life location is just as cool as the fictional one. It represents a time when we built things to last and to inspire. Whether you call it Union Terminal or the Hall of Justice, it remains one of the most significant architectural achievements in the United States.
The fact that it survived the 20th century is a feat of strength that would make Superman proud.
Actionable Next Steps
If you're planning a trip to see this landmark, start by checking the Cincinnati Museum Center official website for their "Rotunda Tours." These tours aren't always publicized but often run on weekends, giving you access to areas like the old Control Tower that the general public doesn't see. For the best photography, arrive during the "golden hour"—roughly 60 minutes before sunset. The way the light hits the limestone facade perfectly mimics the opening credits of the Super Friends and provides the most dramatic shots for your collection. If you're a local, consider a membership; the revenue from those passes is what directly funds the ongoing maintenance of the Art Deco mosaics and structural integrity.
