With a roar of percussion, lightning and song, the Rio Carnival set out this Sunday, February 11, to experience its most powerful moment: the sumptuous parades of the prestigious samba schools. The 12 most renowned schools prepared for a year to win the title of champion after a parade every 60 to 70 minutes. Their fate will be decided by the judges based on exact criteria, the quality of swimwear and costumes, the choice of theme or choreography.
