The village rises in one of the most densely cultivated vineyard areas of the region, in the land of Brachetto, Dolcetto, Barbera, and Moscato, with numerous farms spread across the territory.

Castel Rocchero stands like a sentinel on a hill overlooking an ancient route, used since Roman times to connect Acqui Terme with the Belbo Valley and its surrounding villages.

The first records of the village date back to 967, when Emperor Otto granted extensive lands to Aleramo, whose full story is well documented. The most turbulent events took place around the castle, due to both its strategic position and the exploitation of the surrounding lands and forests from the 1400s onward, culminating in the complete destruction of the village in 1495 by the forces from Acqui.

Afterward, the village passed through the hands of various feudal lords, dukes, counts, and marquises, until 1833, when it came under the Blesi family of Acqui.

The village developed around the hill where the castle once stood. The fortress was destroyed in 1496 and later rebuilt, redesigned more as a residence than a military structure.

Today it houses the town hall: the plastered façade is rather modest, while the interiors retain a 17th-century style.

The 20th-century parish church was built on the site of the old village cemetery. There are five other churches, three of which are in the surrounding countryside. A striking passage through the ancient walls leads to the upper part of the village, where the old castle cellars have been converted into a restaurant.
