The Narrowest Street in Prague

In the beating heart of Old Prague lies one of the city’s most fascinating oddities-the narrowest street of all, Nejužší ulice, measuring only about 50 centimeters wide.

What makes this place unique is the pedestrian traffic light installed mid-passage. Because there’s room for just one person at a time, the light manages “traffic” and prevents collisions-a quirky yet practical solution to an unusual problem.

Watching people wait their turn to pass through this tiny alley is both strange and charming, a true Prague curiosity.




The Devil at the End of the Street

At the far end of Nejužší ulice stands the well-known restaurant Čertovka, whose name translates to “The Little Devil.”

Inspired by Slavic folklore and traditional Czech culture, Čertovka offers an atmosphere that feels both enchanting and timeless-an ideal place to pause, eat, and soak in the fairy-tale spirit of Old Prague.




In Summary

Prague dazzles with grand monuments, but sometimes the tiniest places leave the biggest impression. The narrow street of Nejužší ulice embodies the city’s playful soul-history, humor, and a touch of magic around every corner.
