The Ignis Brunensis is an international firework competition held annually at the end of May and beginning of June in Brno, Czech Republic.
From this moment competing fireworks are presented outside the city centre on the nearby Brno Dam where the effect is increased by reflection from the water.
Each fireworks show lasts about 22 minutes, with synchronized music broadcast by the local radio station.

Local museums, castles and other institutions also participate in the event, with their own programmes.
