The Castle of Monastero Bormida was not originally built as a defensive structure but as a Benedictine monastery, founded around 1050 by monks from the Abbey of Fruttuaria, called by the Aleramici Marquises to reclaim the lands devastated by Saracen raids. The 27-meter tower still visible today was originally the bell tower, and the river flowing a few meters from the southern tower confirms the non-military nature of the building. In 1393, the Benedictines abandoned the monastery, and its feudal history began: the fief passed to the Del Carretto marquises, who in the 15th century added the first defensive structures, transforming it into a castle. The building is a quadrangular structure with an internal courtyard, protected by towers on multiple sides and connected to the former bell tower by a small suspension bridge. On the south facade, there is a two-arched Renaissance loggia with a small stone column. Inside, the rooms on the main floor—transformed in the 17th century—feature mosaic floors and sail and cross vaults with frescoes of floral and geometric motifs. The castle later passed to the Della Rovere family and subsequently to the Genoese Polleri family, finally becoming the property of the Municipality starting in 1880. Today it is open to visitors and is part of the regional circuit "Castelli Aperti".

The castle stands in a dominant position on a rocky spur overlooking the village of Cremolino, about 450 meters above sea level. The village itself is gathered around the castle and is enclosed by a second wall built in the 15th century 1460 by Isnardo Malaspina. Access to the castle is via a drawbridge.

The climb that leads from Canelli to Gancia castle passes through splendid vines. This climb is steep at times and was tackled by the 2023 Giro d'Italia women. The Gancia castle is currently a private villa and cannot be visited: on the other hand, the panoramic views are magnificent.
