Ornamentation of the chapel is remarkable due to its large vitreaux created by the French artist A.F. Bernard in 1991, in Grenoble city. Firstly, there are three windows corresponding to the three accesses; these are extended with semicircular arches and have geometric and vegetal figures, all in poor conditions.

Secondly, there are vertical and semicircular-arched windows of the transept. On the transept right hand side, stained glass windows dedicated to Jesus’ Birth and Crucifixion are displayed. On the left hand side, there are vitreaux dedicated to the Annunciation and Saint Rose of Lima.

Thirdly, there are vertical and semicircular-arched windows of the apse. The central one represents the Sacred Heart of Jesus. Right hand side stained glass window is dedicated to Saint Catherine Labouré, while on the left there is a window devoted to the Scapular of the Passion.

Fourthly, there are the vitreaux of the apse elevated niche; they are three and are smaller, have motifs such as grapevines, big wheat spikes and something that seems to represent the heaven.

Under the right-hand side vitreaux of the transept, there are images of Saint Vincent de Paul and Saint Anthony of Padua. Facing transept windows, there are devotional altars, some of them with very beautiful wooden carvings.

The apse is watched over by the figures of four angels interspersed with the windows. There the Main Altar, made of marble, is located. Besides, there are niches preceding the set of angels and stained glass windows with the images of the Virgin Mary and Saint Joseph.

The central nave depicts some smaller-sized figures. In the choir there is a French organ, whose time of origin has not been determined. Its manufacturer is unknown. However, the organ might have been installed in 1920.
