The Regional Administrative Tribunal for Sardinia is housed in a building inaugurated in 1927, which completes the southwest side of the Piazza del Carmine and originally housed the Provveditorato alle Opere Pubbliche. The building, characterized by eclectic, predominantly Renaissance and Mannerist motifs, was built to a design by architect Augusto Valente between 1925 and 1927 by workers from Calabria. The building has a partially basement floor on which the raised first floor and the three upper floors are located. The lower floor is marked by balustraded windows decorated with faux fan-shaped ashlars, separated by overlapping projecting bands, while the three floors have symmetrical windows surmounted by progressively less rich gables and cornices. The elevation on Carmine Square is concluded by a decorative salient pediment. On the third floor of the building, four paintings by master Filippo Figari, executed between 1928/29 specifically for the walls of a room on the second floor from which they were precisely moved to the present one, are to be found in what is commonly called the “representation room.” The cycle reconstructs in four moments (in order from left to right The Farmyard, The Church, The House and The Village) the rural, religious and domestic customs of Sardinia. The scenes are conceived as a sequence of excerpts of daily life, brought into focus with almost photographic precision detectable in the composition as in the fixity of the images. From this we can understand the strong influence exerted in Figari by the photography of the famous photographer August Sander, whom the artist accompanied on his visit to Sardinia documented in a 1927 reportage.
During and after World War II, the Public Works Department played a very important role in the reconstruction of the city, including through the work of the Civil Engineers.
