the group of volumes include four areas: the palace, with three floors designed in a "u" shape; the galleries which extend from the main building and third rear gallery; the central patio between them; and an ample open space in the rear. the main building includes a grandioso facade, with the main state room elevated, its central corpo protruding and supported by three arches, crowned by frontispiece. the rhythm of the openings of the first floor alternate between curved and triangular pediments, with medallions underpinned by garlands, while the entire structure is surmounted by balustrade decorated with vases and urns.
