Castelrosi Castle

History

The Sienese fortress

The oldest part dates to the 13th century, when it was a fortress of the Republic of Siena controlling the Via Cassia and the Ombrone valley. In the early 14th century it was badly damaged by the men of Uguccione della Faggiola and then passed to the Hospital of Santa Maria della Scala in Siena.

From castle to villa

In the second half of the 15th century it was turned into a villa, at the centre of a farm that still exists today, by Andrea Piccolomini, nephew of Pope Pius II. In the early 18th century it passed to the Chapter of the Cathedral of Siena, until the unification of Italy, when it was bought by the family that still owns it.

What to see

In the early 20th century the complex was extensively remodelled in Neo-Gothic style to a design by the architect Vittorio Mariani, who also created the park and a small Italian garden. Its distinctive feature is the old octagonal tower, raised during the last intervention, at whose base stands the chapel. A clay tennis court built in 1933 is attached to the castle.
