Grüezi!
Welcome to the trick fountains of Basel,
welome to Basel's fountain of carnival.
As you all know, Basel is Switzerland's third most populous city with just about 166,000 inhabitants.
Located where the Swiss, French and German borders meet, Basel also has suburbs in France and Germany.
And: it's a traditional stronghold of Alemannic Carnival.
This fountain, kown as the "Fasnachts-Brunnen", literally translated into "fountain of Carnival", is located at the Theather Square of Basel's inner city.
It was designed by the Swiss artist Jean Tinguely. He is best known for his sculptural machines or kinetic art, in the Dada tradition; known officially as metamechanics.
The Fasnachts-Brunnen of Basel has ten different of these mechanical sculptures / metamechanics inside a large water basin. They all spray different water fountains through the air.
Oh, sorry, that was the wrong spout / water fountain...
...but somehow it has to do with Alemannic Carnival as well! ;-)
...and the WORLD smiles with you!
