A 17th century residence predating the creation of the Park, Villa Mirabello and Villa Mirabellino are picturesquely linked by an avenue lined with a double row of hornbeams. The layout of the central body includes eight rooms with an entrance hall, placed around a large ballroom occupying the height of two floors. On the upper floor, a balcony is located along the perimeter of the ballroom. It served both as a passageway to the bedrooms and as a grandstand from which balls and receptions could be viewed. The walls are entirely frescoed and the vaulted ceiling has a central scalloped medallion in which various allegorical characters and mythological scenes are depicted.
