Mendelian Inspirations in the IGNIS BRUNENSIS fireworks on Saturday, 23 July 2022 over Špilberk


For the twenty-fifth time, the skies above Brno shine with the REGIOJET IGNIS BRUNENSIS international competition of artistic fireworks. After a prelude in Brno-South and four performances at the turn of June and July on the surface of the Brno Lake, the quarter-century-old festival will culminate with a fireworks finale on Saturday, 23 July at 10.30 pm over Špilberk Castle. The pyromusical "Mendelian Inspirations" is dedicated to Gregor Johann Mendel on the bicentenary of his birth.

The musical motif and the construction of the fireworks design are inspired by the work of this eminent natural scientist, mathematician, passionate beekeeper, but also a monk and abbot of the Augustinian monastery in Old Brno. "There is probably the most famous organ piece by Johann Sebastian Bach and attempts to crossbreed fiery peas or the yellow and orange blooming hawk-hornwort. This time in the sky, but very, very close to the abbey garden, where Mendel conducted most of his botanical experiments," adds Jaroslav Štolba, the lead designer of the fireworks from the Flash Barrandov SFX team.

As with all IGNIS BRUNENSIS fireworks, Radio Krokodýl will broadcast the accompanying music on 103 FM. Visitors to the Mendel Festival can watch the show over Špilberk directly from Mendel Square after Ewa Farná's concert.
