Solofra is located in a basin of the Picentini mountains, open on the plain of Montoro-S. Severino that connects the basins of Irno and Sarno and is an important and vital node of the plain of Campania.

The town has been favored in its history and economy by this particular condition.

Its territory was the site of a Samnite outpost on the road between the Sabbath and Irno valleys and of a settlement of the Rmana colony of Abellinum.  

With the invasions his foothills welcomed two high medieval castles protected by the Parish of Sant'Angelo and Santa Maria which was an important and strong point of coagulation in the formation of popular identity. It allowed the gravitation of the Solofran activities towards Salerno from which it depended and of which the territory was tributary.

Occupied by the Lombards was absorbed into the Duchy of Benevento and was part of the gastaldate of Rota (S. Severino). At this time the basin was divided into two territorial entities: the locum Solofre and the locum de sancta Agatha.

In the Norman-Swabian period Solofra became vico and was first part of the county of Rota, then of the fief of Tricarico with whom it reached territorial and administrative autonomy (thirteenth century) becoming a fief of Giordano Tricarico. It was then assigned by his brother, Giacomo, as a dowry to his daughter Giordana, wife of Alduino Filangieri di Candida.

The Filangieri favored the link with the artisan-mercantile reality of Salerno and built in the merchant center of Solofra, the public audience, the Augustinian convent (second half of the fourteenth century).

Following the extinction of the Filangieri branch, the feud passed to the Zurlo of Naples and the Della Tolfa of Serino and, after a brief period of autonomy from the feudal (1535-1555)the Orsini of Gravina who transferred ownership of their principality to the fief and who kept it until the subversion of feudalism (1809).
