The narrowest street in Prague

Today I will show you the narrowest street in Prague. It’s easy to get there – it’s slap bang in the centre, close to the Charles Bridge.

How do I get there?

It doesn’t have its own name, so you have to search for the street called U Lužického semináře. The entrance is from a square and you will probably recognize it easily because a bunch of people will be standing there. Don’t worry, they is no entrance fee, they are most likely waiting for the traffic light to change to green. Or taking selfies.

Wait – traffic lights?

Yes, the street is so narrow (only about 70 cm wide) that the people can’t pass next to each other. They have to let those waiting up come down and then those waiting down can walk up. This is coordinated by simple traffic lights system which makes it a popular attraction.

What is down there?

The photos above show the bottom part of the street. There is the Čertovka restaurant and you will get a chance to see the Vltava river and the Charles Bridge from an unusual point of view.

Why is it actually so narrow?

Prague, as you know, is a medieval city. And in those times the houses were not usually from bricks, but wood. If fire broke out, it could spread very quickly. And these streets were there to stop the fire from spreading across large areas. So this street was never actually built as a street, but as a fire precaution and escape route. The city decided to build these after fires in 1503 and 1541 (source, in Czech). Today, this is the only one that still exists.
