Signal Festival is a dazzling mix of videomapping and light installations taking place over several fall days. Installations are mostly scattered throughout the historic center, although some are more off the beaten tourist path, for example, at Náměstí míru or even the rarely used space under the metronome. Since its start in 2013, Signal has doubled the amount of visitors with over half a million in 2014; The Guardian even ranked it among the 10 best light festivals in Europe. The festival showcases the works of videomapping and light pioneers from not only the Czech Republic but from the world over. Download Signal’s free and navigable-friendly map to plan your route.
