What to do this weekend in Prague: Best events for Sept. 26–28

Prague Art Week is spotlighting the Jindřich Chalupecký Award and Kinke Kooi exhibits this week and they're worth checking out. Dutch artist Kinke Kooi brings her feminist drawings together with works by the award’s Czech laureates. Even better: there are tours and artist talks in English, so you won’t miss any nuance.

In the romantic Havlíčkovy sady (Grébovka) gardens, another vinobraní festival of the season (and one of the most anticipated) lets you wander through grove-lined paths while sampling fresh burčák, regional wines, and tasty bites from local vendors. Expect live folk music, and folk dancing. Sip something crisp and soak in sunset views over the vines.

This 'techno marching band' from Hamburg replaces DJ decks with horns and drums. 11 musicians will take to Lucerna's Grand Hall and impress with their unique covers of electronic songs, opened by Czech DJ NCOL. It’s a rare chance to see a genre-defying ensemble push boundaries between electronic and brass.

This week’s evening highlight: Mozart’s Idomeneo premieres and takes center stage at Národní divadlo. Expect a dramatic journey through power, passion and fate, with Italian libretto and English/Czech surtitles to guide you. Clocking in at nearly 2 hours 50 minutes (with an intermission), it’s a night out worth dressing up for.

Get a crash course in ancient decadence before diving into the latest cut of Caligula. Historian Lukáš Kubín will kicks things off at Edison Filmhub with 'Sex, Power & The Gods: Erotica in Antiquity' (in English), a 30-minute talk diving into how the Romans used sex as status, protection, and even spiritual weaponry. Then comes the infamous, newly reconstructed 4K Ultimate Cut of Caligula—a scandalous cult classic with Malcolm McDowell, Helen Mirren, and Peter O’Toole, shown in its complete, never-before-seen form.

Discover the Vltava returns Sunday for a full-day immersion into Prague’s river. You’ll get to explore hidden corners from Smíchov lock chambers to a secret tunnel under the National Theatre, hop aboard boats, and come face-to-face with the river as you’ve never known it. Stroll the banks with the whole family (or just yourself) and soak in something truly magical.

Heroes’ Day lands at Výstaviště on Saturday, and you can get up close with rescue tech (think fire trucks, police helicopters, army gear), explore a humanitarian aid setup, and dive into hands-on zones where kids can try out escape rooms, fire-rescue tasks or codebreaking missions. Meanwhile, interactive talks, a brand-new podcast stage spotlighting ordinary heroes, and live rescue demos round out the experience.
