A few kilometers far from Alba, Diano is divided in three separated areas: the historical center, the Talloria valley, where many wine-makers have their farms, and Ricca, where the industries are.
From the castle walls it’s possible to see the Barolo vineyards and the hills of the Langhe.
To the Dolcetto di Diano d'Alba the fair is dedicated; it takes place in June.
Its name is probably a tribute to the goddess Diana, patron of hunting and of the woods.
Diano has a millennium-long history: in the Middle Ages it has been a powerful military town, even more powerful than Alba itself.
Occupied and burned down in 1361 by mercenary soldiers lead by Leonetto of England, it was then owned by the Visconti di Milano family, then by the Savoia; it always was contended by the Savoia, the marquis of Monferrato, the dukes of Milan and Venice.
With the peace of Cherasco, in 1631, it definitely became a property of the Savoia family, and of Vittorio Amedeo I di Savoia.
