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".

Located in Borgo Basalone (also known as the new part), this 17th-century palace in typical Genoese style represents one of the few examples of Ligurian architecture in Piedmont. Commissioned by noblewoman Lelia Di Negro—niece of Ambrogio Di Negro, former Doge of Genoa—when, invested with the fiefdoms of the same name and becoming Marchioness of Mombaruzzo and Countess of Quaranti, she decided to move the marquis' palace from the fortified enclosure of the Castle to an even more dominant and spectacular location.

Remains of an ancient Roman aqueduct that ennoble our city, rich in history of the distant civilization of the Roman Empire. Many other remains scattered in the area testify to the importance of the spa since ancient times. In addition, the barbarism exercised over the decades by the various questionable thematic administrations has reduced it to a minimum, leaving the ancient splendor to total decay.
