The ancient Via Postuma ran through the Bocchetta Pass, one of the main routes to Piedmont before the Giovi road was opened

Campomorone developed along this route, in valley of the River Verde, a tributary of the Polcevera. Only a short distance from Pontedecimo, the town became the valley's main centre during the seventeenth century, when the Republic of Genoa began to prefer the Bocchetta to the Marcarolo road: the village began to take on the appearance of a small town with the construction of impressive buildings such as Palazzo Pinelli, then Palazzo Balbi and the Salt Factory, which you see on your left if you are arriving from Genoa. The Salt Factory was built by the D'Amico family, who owned the concession for the sale of salt: this very interesting building combines the functions of commerce (stables, storehouses) and defence (walls, watchtower). Palazzo Balbi is a typical suburban residence, with a central stairway leading to the noble family apartments and a fine garden; it hosted many illustrious passers-by, including the Emperor Charles V and, in 1815, Pope Pius VII. It is currently the town hall building and houses the puppet museum and the museum of mineralogy. Another place of great interest is the Red Cross Museum in Via Primo Cavallieri.
The territory is interesting from a geological point of view: there are grottoes at Isoverde and Gallaneto; until a few years ago the quarries in Pietralavezzara which supplied the green marble that was so popular in Genoa and Europe in the eighteenth century were still operating. The Praglia Plains, which form part of the Capanne di Marcarolo Regional Park, are a favourite spot for Sunday outings. The Gorzente Lakes supply one of the Genoese aqueducts; if you walk along the tourist path you will come across some interesting signs of countryside life, such as snow-traps, charcoal kilns, and chestnut-dryers. It only takes a few hours to walk along this path, which is remarkable for its panoramic views and natural beauty.
