Trojhalí Karolina consists of two reconstructed heritage-protected buildings. During their tenure, they were used for industrial purposes. The electricity produced here supplied the surrounding shafts, mines and smelters. Now an exceptional multi-functional space where, thanks to the unique concept of the covered Náměstí (Dvojhalí) and Ústředná (Sportovišti) – publicly accessible, spacious buildings – you can play sports, attend various events or organize events yourself. An open space sought after not only by city residents, but also by organizers of all kinds of events not only from the Czech Republic.
