Known in Catalonia as La Missa del Gall or “The Rooster’s Mass,” this service commemorates the birth of Jesus and is one of the most anticipated events of the season. Expect beautiful choral music, soft candlelight, and a deeply reverent atmosphere as the basilica glows from within. After the mass, there’s a brief adoration of the nativity scene on the Nativity Façade, connecting Gaudí’s symbolic sculpture work with the spirit of the season.
