Millesimo, located in the Bormida Valley of Liguria, boasts a history stretching back to Roman times, evidenced by archaeological finds in the area.

The town's strategic position along ancient trade routes contributed significantly to its economic and military importance throughout the Middle Ages.

Millesimo played a crucial role in the Napoleonic Wars, serving as the site of a decisive battle in 1796 where Napoleon Bonaparte achieved a pivotal victory against the Austro-Piedmontese forces.

Geographically, Millesimo is situated at the confluence of the Bormida di Mallare and Bormida di Pallare rivers, contributing to its fertile agricultural land.

The Ponte Vecchio, or Old Bridge, a medieval stone bridge spanning the Bormida River, stands as a testament to the town's architectural heritage.

Millesimo's demographics have experienced fluctuations, with a notable decline in population during the 20th century due to emigration towards larger urban centers and industrial areas.

Agriculture, particularly the cultivation of chestnuts, grapes, and olives, remains a significant component of Millesimo's economy, alongside small-scale manufacturing and tourism.

The Church of Santa Maria Extra Muros, dating back to the 12th century, showcases Romanesque architectural elements and contains valuable historical artifacts.

The imposing Castello Del Carretto, though now partially in ruins, offers panoramic views of the valley and recalls the feudal power that once dominated the region.

While not directly a UNESCO site, Millesimo benefits from its proximity to the nearby Langhe-Roero and Monferrato wine regions, a designated UNESCO World Heritage Site.

The town hosts various local festivals throughout the year, celebrating traditional Ligurian cuisine, music, and agricultural products.

Millesimo's local traditions often involve communal gatherings and celebrations linked to the agricultural calendar and religious observances.

The presence of numerous hiking trails and natural landscapes around Millesimo encourages outdoor activities and eco-tourism, attracting visitors seeking a connection with nature.

Although a small town, Millesimo's participation in regional politics and administration contributes to the overall governance of Liguria.

Efforts are underway to promote sustainable tourism and preserve Millesimo's historical and natural heritage for future generations.
