The Palau Sant Jordi was a spectacle of water, lights and sound as the 15th FINA World Swimming Championship was inaugurated with an appeal to preserve water as a source of life.

Scuba diver Eduard Ametlla, 89, also performed an act and delivered the message of conserving water.
A group of 'castellers' built a human tower inside the swimming pool in front of 10,000 spectators, who appreciated the performance.
A total of 230 people took part in the ceremony, including actors, acrobats, springboard divers, synchronised swimmers and volunteers.
A record of 2,293 athletes will compete in the event compared to the 2,220 in 2011 Shanghai.
