The best time to head down to Brno’s dam is after sunset at the end of May and start of June when teams from around the world vie for the top awards at the Ignis Brunensis firework competition. 

This started out as a mere exhibition, but in 2003 things started to get serious and hi-tech pyrotechnics companies started using the event as a chance to show the marketplace what they could do. 

This sense of competition is great news for the public, as the increasingly elaborate displays are reflected wonderfully by the waters of the reservoir.
