The restoration team set up a computerised database in order to make an exhaustive record of the work carried out on each of the stone blocks as well as the restoration treatments applied to them. Each of the dismantled and numbered blocks was identified in the database with an exact description (architrave, cornice, coat-of-arms, etc) as well as its weight, measurements, location and storage, physical condition, treatment and photography (initial and final state).

The definitive restoration started with the application of a treatment to eradicate areas of biological deterioration, applied to all the visible sides of the original blocks as a preventative measure. The areas with high salt content were desalinated while surfaces were cleaned with easily controllable, non-invasive methods that did not involve any risk of damage or loss of surface material. Cracked stones that were not repaired during the consolidation phase as they were out of line, as well as those that needed reinforcing, were pulled together with fibre-glass rods and epoxy resin, ensuring that future colour change would not take place.
