The side chapels
On the left of the main altar there is a chapel dedicated to the Custody of the Holy Land: the coat of arms with a red cosmic cross is shown in the centre. The mosaic that decorates the chapel, a work by the artist Glauco Baruzzi, is entirely dedicated to the celebration of the Order of Friars Minor, with the image of stigmatic Saint Francis and the first Franciscan martyrs. King Robert of Anjou and Sancia of Aragon, figures who significantly contributed to the presence of Franciscans on the Holy Land feature on the jambs of the chapel.
The chapel of the Most Holy Sacrament is on the right, a work by the Spanish artist Rafael Ubeda, who with a very original style inspired by Picasso studied the elements of traditional Christian symbology, representing them on the jambs of the chapel: fish, bread, the anchor. The chapel is dedicated to all the saints of the Church.
In the chapel vault, the artist develops the theme of universal reconciliation after the struggle between good and evil experienced by humanity: the birth of Jesus represents the victory of light over the darkness of evil.
