Prague’s Narrowest Street With Traffic Lights
There are plenty of streets around the world that are famous for being long, short, wide or narrow. However, what sets the narrow street in Prague apart from them is, that is also has a traffic light.
Located in Prague’s oldest neighborhood Mala Strana, this 32 feet long street has a width of about 19 inches.
The two traffic lights have been installed at the both end of the street. The traffic lights are used to signal, whether the passage is occupied or not.
The pedestrian traffic lights were installed for pedestrians’ fun and convenience. It contributed hugely towards the popularity of this passage, as it started to attract travelers.
Although, it may sound fun, it is still a traffic light and the same rules apply to it, as to any other traffic light.
After pushing the walk button, tourists first take pictures and then proceed to walk, not taking the light seriously. So, it is a common occurrence for people to collide with each other.
This place is worth visiting, while exploring beautiful Prague.

UnusualPlaces Field Notes
- Location
- Čertovka narrow passage, U Lužického semináře 24, Malá Strana, Prague, Czechia
- Coordinates
- 50.08793, 14.40954
- Access
- This very narrow, steep stair passage is the entrance to Restaurace Čertovka, not a normal public street. June 2, 2026 reporting says the lower exit gate was ordered locked, so visitors must leave through the restaurant entrance; follow the one-way signals and do not block the doorway or nearby homes. It is not step-free. Confirm the passage is open before making a special trip.
- Admission
- No separate passage ticket or fee is listed. The route is tied to the restaurant entrance, and the restaurant’s opening hours do not guarantee the passage is available to sightseers.
- Time needed
- A brief pass-through/photo stop; an independent Prague guide estimates about two minutes. Queues can form, so keep moving and avoid obstructing the restaurant entrance.
- Best season
- No season is identified as best. Access depends on the restaurant and local passage controls, not the weather season; check locally before visiting.
- Opening hours
- No independent hours are posted for the passage. The restaurant lists March–October 11:30 a.m.–midnight and November–February 11:30 a.m.–10 p.m.; these are restaurant hours, not a guarantee of passage access. The June 2026 city-district decision directs visitors to exit through the restaurant.
