The Labyrinth of Plzeň Historical Underground Secrets

The city of Plzeň sits on a massive system of corridors. These tunnels date back to the 14th century. Local citizens dug into the soft sandstone to create storage space. This helped keep food and beer cool during hot summers. It also provided a safe place during times of war.

The total length of these passages is nearly 20 kilometers. Only a small portion is open to the public today. Walking through these halls feels like stepping back in time. You can see old wells and drainage systems from centuries ago. It is one of the most weird and unusual museums in Plzeň to visit.

The underground was also vital for the city's water supply. Workers carved deep wells directly into the rock. Some of these wells are still visible during guided tours. They represent the engineering skill of medieval builders. These structures are a key part of the Plzeň Region history.
