Villa Arceno was built towards the end of the seventeenth century by order of cavalier Flaminio del Taja. In the early XIX century, it became property of the Piccolomini Clementini family. Around 1833, it was furnished with a large park, realised on a project by architect Agostino Fantastici, and conceived as «a pleasure-ground destined to the cultivation of flowers and citrus plants, abundant in woods of a wide variety of trees, canals, lakes, fountains and little temples». Typical of Fantastici’s eclectic taste, the park is a beautiful example of a so-called "landscape" garden with a romantic influence, which developed in those years, following the diffusion of the "English" garden. Amidst a dense woodland vegetation that frames a manmade lake, we find rare plants such as the sequoia, camphor tree, cedar of Lebanon and the dwarf palm.

As with the other gardens, the garden of Villa Arceno too, has interesting solutions in hydraulic engineering with practical purposes (such as irrigation), as well as aesthetic purposes (fountains, lakes, nymphaeums). The garden’s manmade lake is supplied by the waters of the Ombrone river by means of the successive overflowing of four lakes; it is also connected to the "Boat House" by means of a small manmade canal.
