Palazzo della Questura, Naples, Police headquarters palace in Naples, Italy

The Palazzo della Questura stands between Via Medina and Via Armando Diaz, with its main facade on Via Diaz facing Piazza Matteotti. Built 1935–1938, it has a plain marble cladding rather than the bold architectural features of nearby buildings, but its large size gives it a severe, monumental look. The Latin inscription QVESTVRA sits at the top of the facade.

Built between 1935 and 1938 as the new police headquarters for the first lot of the Rione Carità, the building was to be inaugurated in February 1939. A shortage of iron materials, caused by rearmament and international embargoes, delayed the inauguration until 1940. Before then the questura had been housed in Palazzo San Giacomo and briefly in Palazzo Caracciolo di Santobuono on via Carbonara.

The building design reflects the architectural style of 1930s Italy with its monumental structure and Latin inscription QVESTVRA on the facade.

The building sits at a central location in the heart of the city, easily reachable from major transit points. Visitors should be aware this is an active administrative site, so access to certain areas is restricted.

The portal on Via Diaz keeps the regime's only surviving trace: four pairs of fasces carved across four frames on three rows, with a fourth upper row of four frames each holding a fascist eagle. The two marble reliefs flanking the portal were removed after the fall of Fascism and replaced by the bronze cogwheel of the Republic on the left side.
