The passing of time caused serious damage to the fresco. During the civil war a mortar bomb destroyed part of the vault and the experts from San Pío V Museum proceeded to restore this, rebuilding the structure of the damaged vault and retouching the mural by means of a neutral inpainting which did not define the forms destroyed.

In the photo taken in 1997 you can see the poor state of the fresco very clearly, with a lot of dirt on the surface, damage caused by damp, losses of the pictorial layer as well as cracks all over the surface.
