The Singing Fountain is one of the dominant features of Mariánské Lázně. It plays daily at every odd hour between 7 a.m. and 7 p.m., and at 9 p.m. and 10 p.m. with a projection and a colourful light show. The gala opening of the season takes place at 9 p.m. on 30 April every year, with operation ending at the end of October or start of November. The Singing Fountain is formed of a circular basin with a diameter of eighteen metres and twelve-part stone sculpture in the form of a stylised flower, the central part of which is made from polished steel. The fountain as a whole is managed by computer, allowing the formation of interesting spray combinations and coloured lighting.
