Kőbányai cellar

The Kőbánya Cellar Labyrinth in Budapest's 10th District is the largest underground vault system in Hungary. Its history goes back to the Middle Ages, when limestone was mined underground in the Kőér region. This stone was later used to build important Budapest landmarks such as the Parliament, the Chain Bridge, and the Citadel. Over time, the disused tunnels were converted into wine cellars and later into beer breweries, with the Dreher family leaving a strong mark on the area from the 19th century onward. During World War II, the vast chambers were used as a secret production site for aircraft engines and as an air-raid shelter for the civilian population.

Today the labyrinth covers an estimated area of 180,000 to 220,000 square meters, with a total tunnel length of roughly 32 to 35 kilometers. The passages are mostly three to six meters wide, while the halls rise up to ten meters high. The deepest points lie about 30 meters below the surface. Because of the nature of the limestone, the walls are often damp and covered in mold, and some areas are permanently flooded with groundwater. These submerged zones give qualified divers the chance to explore the underground world. The air temperature stays cool all year round.

You can experience the site on guided tours, which are offered every year during the László Days. These tours lead through the historic tunnels and to the Havas Villa, one of the best-known buildings associated with the complex. Besides offering a look into history, the labyrinth also serves as a venue for sporting events such as mountain bike competitions and running events. The underground network is a fascinating testament to the city's industrial past and offers a unique glimpse into the hidden side of the Hungarian capital.
