Castelnuovo Berardenga is located between Chianti Classico and "crete senesi" (the typical southern Siena landscape). Castelnuovo village stands on a pleasant hill, bordered by Ombrone and Malena streams, at the crossroads of the ancient roads coming from Siena, High Arno Valley and Chiana Valley.

The name Castelnuovo means "new castle" and dates back to 1366 when Siena Repubblic ordered its construction near Poggio ai Frati. At that time Castelnuovo ruled all the little villages in its district. The sighting tower of Poggio ai Castelli still exists and from the top it you can view the wonderful surroundings.
