Jihlava underground

The Yahlava labyrinth or underground passages are spread throughout the city, with a total length of about 25 km. They were found under almost all the houses in the historical part of the city, and for this reason they have been declared a protected area of the municipality. What distinguishes these corridors most is the bright lighting that emerges from their walls in the dark, which is believed to be due to the presence of a chemical substance from which this light is emitted, and you can take a tour inside the corridors to learn about them and their history and it takes 40-50 minutes.
