It a huge, illuminated fountain. At night you can see a fantastic light show with music here in the fountain. According to the played music the lights change their colors and the water nozzles inside the fountain modify their direction and their intense. What a spectacle!!!
During winter this only happens on week-ends, but during summer every night. It was very crowded, so go early to get a good spot. I can only remember the song played last: “Barcelona” by Freddy Mercury and Montserrat Caballé.
A very impressive experience (although a bit wet in some places because of the wind distribution the fine water in the air).
Enjoy the fountain.
