What’s the Deal with Brno’s Astronomical Clock? A Bizarre Monument with a Wild Backstory

If you find yourself in Brno, the Czech Republic’s second-largest city, and spot what looks suspiciously like a modern art installation—or, let’s be honest, a giant black bullet-shaped sculpture—standing tall in the main square, you're not alone in wondering: What the heck is this thing?

That six-meter-tall, sleek and slightly controversial structure is Brno’s astronomical clock, also known as the Brno Orloj. And behind its bold design is one of the most delightfully strange stories you’ll find in Central Europe—complete with clever citizens, historical drama, and daily glass marble souvenirs.

Let’s dive into the legend, the design, and the quirky traditions behind one of Europe’s weirdest clocks.

A Quick First Impression: Wait… Is That What I Think It Is?

Yes. You're not the only one who’s noticed the, um, phallic shape of Brno’s Orloj.

Made from polished black granite and towering over náměstí Svobody (Freedom Square), the clock has drawn plenty of attention for its suggestive appearance since its installation in 2010. Tourists often mistake it for a piece of contemporary art or a misunderstood rocket ship. Locals, with typical Czech humor, sometimes call it “Brno’s dildo.”

But don’t let its provocative silhouette fool you—this clock has deep historical roots and commemorates a key moment in the city’s past.

The Story Behind the Clock: Brno Outsmarts the Swedes

To understand this odd landmark, we have to rewind to the Thirty Years’ War, a brutal conflict that ravaged Europe from 1618 to 1648. In the war’s final year, Swedish forces laid siege to Brno in an attempt to weaken the Habsburg empire.

The Swedes, led by General Lennart Torstensson, promised that if they couldn’t take the city by noon on a certain day, they would give up and retreat. The citizens of Brno, exhausted but determined to hold out, decided to try something clever: they rang the noon bells at 11 AM.

Hearing the bells, the Swedes believed the deadline had passed and—true to their word—retreated.

It was a bold bluff that worked. And more than 350 years later, the city decided to memorialize this event in the most Brno way possible: with a marble-dispensing phallic clock.

How the Brno Orloj Works: Yes, It Dispenses Marbles

Every day at 11:00 AM, the Orloj honors Brno’s clever wartime maneuver by releasing a small glass marble from one of its four openings. If you’re standing nearby, you can try to catch one—locals and tourists alike gather around the base of the clock for the daily event.

The marbles are about the size of a large gumball, and each is unique. Some feature colors or symbols like Brno’s coat of arms, and they’ve become fun collector’s items or quirky souvenirs from your trip. But heads up: it’s surprisingly competitive. You’ll want to get there early and claim a good spot if you want a chance to catch one.

It's part historical tribute, part urban game—and it’s totally weird in the best way.

More Than a Gag: The Orloj Is a Modern Astronomical Clock

Though most people focus on its odd shape and marble rewards, the Orloj is actually an astronomical clock, inspired by other historical timepieces in Central Europe—like Prague’s medieval astronomical clock in Old Town Square.

The Brno version, however, puts a modern spin on things. It’s digital, sleek, and minimalist, using a system of rotating rings and time indicators. You probably won’t be able to tell the time just by looking at it (don’t worry, no one else can either), but it’s designed to track:

  • Standard time

  • Solar time

  • The position of celestial bodies

Honestly, most people visit more for the marbles and the legend than for the timekeeping, but it’s cool to know there’s actual clockwork going on beneath the surface.

Why the Brno Orloj Is the Perfect Symbol of the City

Brno has a reputation for being the quirky little sibling to Prague. It's artsy, intellectual (home to several major universities), and has a subtle but confident vibe. It’s the kind of place that celebrates history and has a sense of humor about it.

The Orloj perfectly reflects this duality: it’s rooted in centuries-old legend, yet completely modern—and just irreverent enough to keep things interesting.

Plus, it’s interactive. A tourist attraction that rewards you with a little glass souvenir? We’re in.
