Things to Do in Brno Underground

Brno Underground contains over 50,000 human bones in its ossuary—the second-largest bone collection in Europe after Paris. This network of medieval cellars, tunnels, and chambers stretches for kilometers beneath the Czech Republic's second-largest city. Storage spaces first. Merchants and brewers carved these areas in medieval times for practical storage, then expanded them over centuries into one of Europe's most impressive urban underground systems. Each section tells different stories. Some house active wine cellars and beer storage, others contain medieval fortifications and World War II air raid shelters that reveal Brno's layered history from the 13th century onward.

Moravian cuisine dominates Brno's food scene with hearty dishes like svíčková (beef sirloin with cream sauce) and Moravian sparrow ( shaped pork and beef). Several microbreweries operate in historic buildings here. Some use parts of the underground network for fermentation and storage—worth seeking out. Wine matters more than you'd expect. Brno sits in central Moravian wine country, so restaurants stock excellent local bottles that pair well with the heavy traditional food. Restaurants range from traditional pubs with generous portions to upscale places that'll surprise you with their sophistication.

May through September offers the best weather for combining underground tours with surface exploration. The underground stays consistently cool year-round though. Summer brings longer tour schedules but also larger crowds and higher accommodation prices. Winter visits work particularly well for underground wine tastings, with fewer tourists and full access to most sites. The underground spaces provide welcome relief from summer heat above. In winter they feel surprisingly warm compared to the chilly streets.
