The Villa Fagnano is a baroque-style rural palace structure located near the town of Castelnuovo Berardenga, a few miles outside Siena, region of Tuscany, Italy.
The house was erected in 1698 by the Signor Bandini Piccolomini, at the site of a former fortress house, using the designs of Giovanni Battista Piccolomini. An inventory from 1840, noted the villa was decorated with paintings by Francesco Simonini, and that the chapel had an altarpiece by Casolani, possibly Alessandro.
The villa retains a walled Giardino all'italiana with ordered geometric blocks of flowerbeds, framed by box hedges and punctuated with lemon trees in vases. In the center is a circular fountain with modern statue of Neptune and an allegory of the four seasons, both by the sculptor Romanelli. In the garden is a nymphaeum with a fishpond and three niches adorned with statues.
