Firework's national colours to mark Czechoslovak centenary

The firework will start at the Letna Hill on the left bank on the Vltava River at 18:00, like a year ago.

It will last 11 minutes and cost about one million crowns.

Apart from the establishment of Czechoslovakia, one of the successor states to the Austro-Hungarian empire, on October 28, 1918, the firework will mark the milestones in the country's history such as the Prague anti-Nazi uprising of May 1945, the Prague Spring communist reform movement of 1968 and the anti-communist "Velvet Revolution" of 1989.

Czechoslovakia, a common state of Czechs and Slovaks, peacefully split into two independent states, the Czech Republic and Slovakia, based on the two nations' agreement on January 1, 1993.

The Prague firework will include some unusual effects such as new types of Japanese aerial shells, fire mushrooms simulating an air raid, tall red columns and shells with an effect of the Czech flag.

The City Hall considered whether to have the firework be silent in order not to disturb wild and pet animals.

Experts, nevertheless, said this is impossible in view of the planned show's extent.

Nevertheless, the organising firm has promised to make the show as nature-friendly as possible and discuss the relevant measures with environmentalists.
