On the night of December 24th, as tradition dictates, numerous churches in Mallorca will celebrate Matins with the Song of the Sibyl as its central element. Year after year, this ceremony fills the churches with worshippers and curious onlookers eager to experience firsthand one of the most unique expressions of Balearic cultural heritage. The Song of the Sibyl was recognized in 2010 as an Intangible Cultural Heritage of Humanity by UNESCO. This piece of medieval origin, which symbolically announces the arrival of Judgment Day, continues to resonate on Christmas Eve in different parts of the island and keeps alive a tradition passed down from generation to generation.
