This celebration takes place every year in Seville Cathedral, and the traditional Seises dance is performed.
The Day of the Inmaculada Concepción is celebrated in Seville with the Seises dance. It is a liturgical dance that is several centuries old in which the Seises (choirboys) dance in front of the main altarpiece in the cathedral. They only do it three times a year. On the eve of the celebration there are songs in honour of the Virgin in Plaza de la Inmaculada.
