ABSTRACT In Italy, from 1930–1940, many governmental palaces were constructed, being characterized by monumental massive façades, realizing a simplified neoclassical architecture. This article deals with one such examples, the “Banco di Napoli” Palace in via Toledo in Naples (Italy). The building was designed by Marcello Piacentini, eminent architect of the fascist regime. Concrete was used as novel building material, both reinforced with metal bars or lattice structures and as block elements, settled up in masonry walls, and travertine was used as cladding, laid down with hidden metal joints and directly exposed to atmospheric agents. The present study focuses in particular on the typical monumental façade of the palace, with the purpose of investigating the cracking out-lines surveyed at the top level. The façade opus and cracking layout were accurately noticed through visual inspection and non-destructive techniques, such as endoscopy and pacometry. Thus, the structural assessment of the façade fabrics, by matching the outputs of in-situ tests, laboratory experiments and structural analysis was carried out in order to evaluate the structural safety and detect the points of weakness of the structures, leading to the identification of possible retrofitting interventions.
