The wise men will arrive at the Portal de la Pau, near the Columbus statue at the old port of Barcelona at precisely 5:30 pm. At 6:30 they´ll start the parade around the city, acompanied by a royal retinue of 900 people including artists, volunteers, municipal police & students from music & dance schools.
The theme of this year´s parade is science & magic, to mark the Year of Science. According to El País, despite being considered magicians, the three kings are also eminent scientists and plan to perform magic tricks while sharing with the kids their knowledge of physics, mathematics & chemistry.
