A crowd of people gathers in the Eastern Finnish city of Imatra on a bridge overlooking Imatrankoski rapids. At the same time every day, the river's almost century-old dam is opened and water rushes under the bridge, to the sound of music. It is a popular attraction especially for Russian tourists. But since the end of July, the show has kicked off with the Ukrainian national anthem, to protest the Russian invasion. Meanwhile, in the nearby city of Lappeenranta, the Ukrainian national anthem is played every evening above its city hall, overlooking shopping centres popular with Russian tourists.
