Costigliole d’Asti castle overlooks the town and characterises it. For Costigliole’s inhabitants, it is the ideal place for celebrations and meetings. Its history is linked to that of the local noble families: the Asinari of San Marzano, the Verasis, the Medici del Vascello, and the Rorà. Among the historical personalities that have lived in it, a special mention should go to Filippo Asinari of San Marzano, plenipotentiary of the Royal House of Savoy, a punctilios scholar and wine expert to whom we owe the considerable boost in local viticulture in the 19th century. Another even more well-known resident of the castle was Virginia Verasis, better known as Countess of Castiglione, to whom Cavour entrusted the delicate job of ambassador of Piedmont to the Parisian court of Napoleon III. From May to November, the castle is open for art and photography exhibitions.
