Zerba is situated in the Boreca Valley and it is possible to reach it following State Road 45 Piacenza – Genova, and then turning onto Provincial Road 18.
It is the least populated village of Emilia Romagna and it lays in the western part of it.
Boreca Valley, formed by Boreca Stream, a tributary of the river Trebbia, lays in the core of a large area called “Appennino delle 4 province(The Apennine of the 4 Provinces)”, where the mountains of the provinces of Piacenza, Genoa, Alessandria and Pavia border and are culturally grouped with common habits and traditions.
The mountain landscape is extraordinarily beautiful and unspoilt: the mountains rich in clear waters are covered by high prairies above the woods, while the valley bottom is characterized by overhangs on the Boreca.
A legend tells that Zerba was founded by some Carthaginian soldiers of the army of Hannibal who retreated to these areas after the Battle of the Trebbia (Rivalta, 218 BC). This would be the reason for the similarity between some place names in the Boreca Valley and some in Tunisia: Zerba/Djerba, Suzzi/Sussie, Bogli/Bougie; an ancient mule track is also called the Hannibal Road.
The territory, after the Roman conquest passed to the Lombards and to the government of the powerful Abbey of San Colombano di Bobbio. Zerba, like the surrounding areas, was then ceded as a fief to the Malaspina Family, who were the landowners of the area until the Napoleonic suppression.
Zerba is a small village rich in history formed by 5 groups of houses, each one characterized by a monument.
In the upper part of Villa Soprana, there is the church of Saint Michael Archangel, patron Saint of the village. In the Middle Ages it was a monastic cell under the Church of Saint Peter in Ciel d'Oro in Pavia. There is also a rustic building dated from the XVI century, probably a Malaspina house.
In Villa Lisamara you can admire the still working old fountain.
In Villa Scarbione there is the Town Hall of the XX century.
