The restoration of the façade of Palazzo Sanuti Bevilacqua

The palace's diamond ashlar façade, a precursor to the more famous Palazzo dei Diamanti in Ferrara, had not been restored in the past except for sporadic reconstructive actions, occasional maintenance additions or experimental tests. The restoration helped to preserve the original material of the façade: not only the yellow and grey sandstones that make up the diamond pattern and the windows, the precious and rare wrought iron balcony with copper inserts above the portal at number 31, the cornice composed of three wooden species, but even some fragments of the surface finishing layer, which survived in the undercuts of the frieze, on some ashlars and on the mullioned windows, which contributed to the preservation of the friable sandstones and which in the past gave the façade the appearance of a monolithic whole. Traditional restoration methods (suction, removal, brushing) were used to remove deposits of atmospheric particles, while the black crusts covering the portals, the sub-arches of the mullioned windows and other moulded elements, where the plastic modelling was more delicate and complex, were treated with a laser beam irradiation that allowed the selectivity of the cleaning to be calibrated, mitigating the invasiveness of the stone support. Limited and punctual interventions were carried out to replace and supplement the sandstone, which mainly involved the current seat in contact with the road.
Careful and meticulous work, therefore, that has returned the city to the original appearance of the façade of one of its most historically rich buildings.
