Guided Tours to Villa Brandi
On the morning of the second Saturday of each month, you can take a guided tour of Villa Brandi, just outside Siena in the countryside of Vignano. May 12th will be the next opportunity to do so.
The villa dates to the sixteenth century, and is now filled with works of art and furniture from the eighteenth century, when it was bought by the Brandi family.
The tours are free, but a reservation is required. For more information, check out Siena's official tourism site.
