You’re driving into downtown St. Louis, and you see it. It isn't the Arch—though that's usually what people are looking for. It’s this massive, somewhat intimidating tower that looks like a skyscraper but feels like a temple. Most people just call it the "Eagleton building," but its official title is the Thomas F. Eagleton US Courthouse. Honestly, if you didn’t know any better, you’d think it was a luxury hotel or a corporate headquarters. It’s actually the largest single courthouse in the United States.
That’s a big deal.
When it was finished back in 2000, it basically changed the skyline of the city. We aren't just talking about another office block. This thing is 557 feet tall. To put that in perspective, if they had built it the "traditional" way, it would have been taller than the Gateway Arch. The architects had to get creative because nobody wanted a building overshadowing the city’s most iconic monument.
The Tower of Justice: Why the Eagleton Is Huge
So, why is it so big? Basically, the federal government needed a lot of space. The Thomas F. Eagleton US Courthouse houses the U.S. District Court for the Eastern District of Missouri and the U.S. Court of Appeals for the Eighth Circuit. That’s a massive jurisdiction covering seven states.
It has about 1.3 million square feet inside.
The height comes from a design trick called "split-level stacking." Usually, you’d have a courtroom and a judge’s chamber right next to each other on the same floor. But courtrooms have high ceilings—they’re two stories tall. Offices don’t need that. So, the architects at Hellmuth, Obata & Kassabaum (HOK) decided to stagger the floors. You’ve got these massive, airy courtrooms on one side and two levels of offices on the other. It’s super efficient, even if it makes the elevator buttons kinda confusing for a first-timer.
A Modern Take on Classic Vibes
If you look at the outside, it doesn’t look like a glass box. It feels heavy. Important. The architects used a "tripartite" scheme, which is just a fancy way of saying it has a clear bottom, middle, and top—sort of like an old Greek column.
The original plan was to use real limestone.
But, as it usually goes with government projects, the budget got tight. They switched to architectural precast concrete. Honestly, you can’t really tell. The concrete was made to look like limestone, with different textures and shades that change color depending on the time of day. Sometimes it looks a bit pink; other times, it’s a warm, sunset red. It’s capped off with a stainless steel dome that catches the light in a way that’s pretty spectacular when the Missouri weather is doing its thing.
What Happens Inside the Thomas F. Eagleton US Courthouse?
Most people only go inside for jury duty or because they’re in some kind of legal trouble. But if you do get a chance to walk in, the first thing you see is this five-story rotunda. It’s all glass and stainless steel, and there’s a giant compass star on the floor.
It feels very "law and order."
There are 25 courtrooms in total. Most of them have these giant windows, which is actually pretty rare for a courthouse. Usually, courtrooms are windowless boxes so people don't get distracted. Here, you get these incredible views of the Mississippi River or the city. The only one without windows is the En Banc courtroom on the 28th floor. That’s where all the judges from the Eighth Circuit gather for the really big, high-profile cases.

The Man Behind the Name
The building is named after Thomas F. Eagleton. He was a U.S. Senator from Missouri who did a lot of things, but most people remember him for being George McGovern's vice-presidential pick for about 18 days in 1972. He had to step down after it came out that he’d had treatment for depression.
It was a different time.
But in Missouri, he was a legend. He co-authored the Clean Air Act and the Clean Water Act. He even helped bring the Rams to St. Louis (back when that was a thing people wanted). He was actually at the dedication of the building in September 2000, just a few years before he passed away.
Is It Worth a Visit?
If you’re an architecture nerd or just curious about how the federal government spends $186 million, yeah, it’s worth a look. The Thomas F. Eagleton US Courthouse is located at 111 South 10th Street.
- Security is tight: You're going to go through a metal detector. Don't bring anything weird.
- Check out the Judicial Learning Center: It’s on the first floor and it’s actually pretty cool. It’s geared toward students, but it explains how the court system works without being boring.
- The Law Library: It’s double-height and has some of the best views in the city.
The building has actually been a bit of a catalyst for the area. Before it went up, that part of downtown St. Louis was pretty much just old warehouses. Now, you’ve got hotels and apartments in the Cupples Station district right next door. It turned a quiet corner of the city into a bit of a hub.
Common Misconceptions
People often think this is the "Dred Scott" courthouse. It isn't. That’s the Old Courthouse with the green dome down by the Arch. The Thomas F. Eagleton US Courthouse is the modern powerhouse that took over when the old buildings couldn't handle the caseload anymore.

Another weird fact: It’s the second tallest judicial building in the world.
Only a building in Brussels is taller. So, while it might just look like another skyscraper to some, it’s actually a record-breaker sitting right in the middle of the Midwest.
If you are planning to visit, try to go on a clear day. The way the light hits the stainless steel dome and the "simulated limestone" facade is something you sort of have to see in person to appreciate. It makes the whole "justice is dignified" thing feel a lot more real when it's wrapped in a 29-story tower of granite and glass.
Actionable Insight: If you're visiting St. Louis for the architecture, start at the Gateway Arch, walk past the Old Courthouse, and end at the Eagleton building. It gives you a perfect timeline of how the city’s identity—and its relationship with the law—has evolved over 200 years. Just remember your ID; you'll need it to get past the front desk.
