Castello and Petraia, situated a mile apart beyond the village of Quarto, were both built by Buontalenti, that brilliant pupil of Ammanati’s who had a share in the planning of the gardens behind the Pitti. Castello stands on level ground, and its severely plain façade, with windows on consoles and rusticated doorway, faces what is now a highway, though, according to the print of Zocchi, the eighteenth-century engraver, a semicircular space enclosed in a low wall once extended between the house and the road, as at the neighbouring Villa Corsini and at Poggio Imperiale. It was an admirable rule of the old Italian architects, where the garden-space was small and where the site permitted, to build their villas facing the road, so that the full extent of the grounds was secured to the private use of the inmates, instead of being laid open by a public approach to the house. This rule is still followed by French villa-architects, and it is exceptional in France to see a villa entered from its grounds when it may be approached directly from the highroad.
Behind Castello the ground rises in terraces, enclosed in lateral walls, to a high retaining-wall at the back, surmounted by a wood of ilexes which contains a pool with an island. Montaigne, who describes but few gardens in his Italian diary, mentions that the terraces of Castello are _en pante_ (sic); that is, they incline gradually toward the house, with the slope of the ground. This bold and unusual adaptation of formal gardening to the natural exigencies of the site is also seen in the terraced gardens of the beautiful Villa Imperiali (now Scassi) at Sampierdarena, near Genoa. The plan of the garden at Castello is admirable, but in detail it has been modernized at the cost of all its charm. Wide steps lead up to the first terrace, where Il Tribolo’s stately fountain of bronze and marble stands surrounded by marble benches and statues on fine rusticated pedestals. Unhappily, fountain and statues have lately been scrubbed to preternatural whiteness, and the same spirit of improvement has turned the old parterres into sunburnt turf, and dotted it with copper beeches and pampas-grass. Montaigne alludes to the _berceaux_, or pleached walks, and to the close-set cypresses which made a delicious coolness in this garden; and as one looks across its sun-scorched expanse one perceives that its lack of charm is explained by lack of shade.
