The gardens are those of the royal palace of Portici just outside Naples, built from 1738 to 1742 for King Charles III of Naples and Sicily and his queen, Maria Amalia of Saxony. The gardens were later described as 'at the east on the slopes of Vesuvius: they are immense, little adorned, but with many trees that are always green, especially service and arbutus trees, which feed the thrushes that abound there.' (Corografia dell'Italia, 1834). The small buildings in the foreground may be part of the royal menagerie.
