It is a municipality in the province of Alexandria, located on a tuff stone hill, in an area surrounded by vineyards, where three rivers merge into one: Paradiso, Rotaldo and Gattola. A small group of bright colored houses, between which stands out clearly the churches Bell tower and the Civic tower. The antique part of the main centre is characterized by the presence of old buildings divided by a classic medieval grid of narrow streets and several districts and villages scattered in the nearby countryside. Fundamental to the local economy is the production of wines, and important income also comes from vegetable and crop cultivations and the exploitation of the tuff stone caves.
The first documented evidence of the existence of the village date back to year 1000. For its particular geographical location, Rosignano was fortified by the construction of three castles: one built to defend the old centre, the castle D'Uviglie and the castle of St. Bartholomew. In the mid XIII century the town acquired autonomy and was proclaimed municipality, even though the community swore allegiance to the Marquis William VII. Its statutes were completed under Manfredo IV of Saluzzo. Over the following centuries, Rosignano followed the fate of all the noble families historically present in the territory of the Monferrato area, such as: the Aleramici, the Paleologi, the Gonzaga, the Savoy and finally the French. During the Napoleonic era it became the capital of the Canton and in this way it gained importance and developed considerably.
