The Secret World Beneath the Streets

Brno is the second-largest city in the Czech Republic. It has a long and complex history. Much of this history is hidden underground. For centuries, residents used the soft soil to dig cellars. These spaces served many purposes over the years. They were used for storage, safety, and even science. You can learn more about these sites in our Brno underground labyrinths guide.

The city center sits on a network of tunnels. Many of these were forgotten for decades. Construction projects in the 20th century rediscovered them. Engineers found vast rooms and narrow passageways. Some were simple storage units for wine. Others were elaborate chambers used by local officials. Today, the city has restored these spaces for the public.

Visiting the underground offers a unique perspective. You escape the noise of the modern city. The air becomes cool and damp. You can see the original brickwork from hundreds of years ago. It is a journey back in time. Most tours are led by expert guides. They share stories of the people who lived and worked here.

Without modern cooling, they needed the underground. The cellars kept food fresh during hot summers. Each merchant owned a private cellar under their stall. Eventually, these separate rooms were linked together.

It adds a layer of mystery to the tour.

The labyrinth also served as a place of punishment. You will see old stocks and cages in some chambers. These were used for dishonest merchants. If someone sold bad food, they faced public shame.
