The Royal Palace was the seat of legislature of the Italian city for a long time. Today it fills in as a social focus and home to works and exhibitions. Originally made with a structure of two patios, the castle was then somewhat decimated to account for the Duomo. The royal residence is situated to one side of the exterior of the church inverse the Galleria Vittorio Emanuele II. The exterior of the building takes after the style of the old patio, shaping a break in regard to Piazza del Duomo, known as the Piazzetta Reale.
