The Brno Astronomical Clock (Brněnský orloj) is probably one of the oddest monuments I’ve come across during my travels. As such, it ranks as one of my favorite sights. The clock is not only super weird – it’s also steeped in some incredible history.

The Phallic-Shaped Brno Astronomical Clock

This huge black bullet-shaped marble monument can be found in Brno’s main square, Náměstí Svobody or Freedom Square. The Brno Astronomical Clock measures 5.8 meters high and 1.7 meters wide. Designed by sculptors, Oldřich Rujbr and Petr Kameník, construction on the obelisk took three years and was unveiled to the public in 2010. 

The cost to build the clock came in at about half a million Euros. And it was oh, so worth it! 

Each day at 11:00, music plays, and a bunch of colored glass marbles are ceremoniously released. Onlookers can catch them from one of the clock’s four openings and then keep the marble as a souvenir. The clock actually is a functioning clock but bizarrely, isn’t an astronomical clock as the sculpture’s official name suggests.

Despite being in the shape of a bullet, the ever-so-obvious phallic shape encourages visitors to take silly photos of the clock. I know that I had a pretty good time watching people have a lot of fun taking slightly inappropriate photos. Rumors abound that locals have some pretty dirty nicknames for the Brno astronomical clock too.

So what’s the story behind this cock? I mean the clock … 🙃

It all goes back to 1645, just as the Thirty Years’ War was winding down and the city of Brno was busy fending off the almighty and until that time, undefeated Swedish military. The resolute residents of Brno refused to surrender and were able to hold the Swedes at bay for almost three months. 

Realizing they were nearing a stalemate, the Swedish commander communicated that his army would leave the city if they weren’t able to gain complete control by noon the next day. Clever locals turned the city’s clock to read noon one hour early, at 11:00. Accepting defeat, the Swedes retreated and fled the city, leaving Brno to celebrate their unlikely battle victory.

The Brno astronomical clock was built to commemorate the win. In addition to the daily clock ceremony, the bells at the nearby cathedral still ring one hour early each day as well.

Paying For Things in Czechia

What you need to know about how to handle your money in Czechia:

1) The country has its own currency, the koruna (CZK).

  • While most places will accept bank or credit cards, smaller shops often only take cash. Get yourself some cash at a local bank machine. 
  • If you do pay by card, you’ll be asked which currency you want to pay in – choose to pay in the local currency (RSD), as you’ll save money on the exchange rate.

Good To Know About Brno

What do you need to know about Brno, Czechia? Some of our top tips:

1) To fully experience Brno and the country itself, book yourself on a guided tour.

2) Is Brno safe? I can only answer this from an anecdotal perspective – as a woman traveling solo, I felt safe in Brno and didn’t encounter any difficulties. However, the experience for people of color could be entirely different. It’s not the most ethnically diverse city and back in 2015, there was strong resistance to the mass refugee migration from many citizens. One person in Prague even approached me to sign a petition to not allow migrants into the country! Of course, I refused to sign such an offensive document. Read this interview, done in 2020 where people of color in Czechia discuss their experiences.
