The frazione of Vignoni houses a castle, a residence of the Salimbeni in the 12th century. It includes a top-less tower and a Romanesque church, once housing a crufix by Giambologna, now in the Museum of Montalcino. Annexed is also the (rebuilt) 15th century Palazzo degli Amerighi, where a plot was set against the Spanish who menaced Siena in 1558–59.
