This weekend most of the Part Forana (the whole island except Palma) in Mallorca will celebrate the festival of Sant Antoni (Saint Anthony Abbot) and the demons, which marks the start of the winter solstice. Sant Antoni’s eve is one of the most magical nights on Mallorca, which celebrations have their origins in ancestral fertility rituals. A crazy night of fun, with the popular culture as main character.
