San Marzano sul Sarno

San Marzano sul Sarno is a town and comune in the province of Salerno in the Campania region of southern Italy, situated about halfway between Autostrade A3 and A30.

The territory of the Sarno valley presents the first traces of human presence between the 9th and 6th centuries BC, a period to which numerous necropolises date back with around 1,400 pit tombs, attributed to the Sarrastri population.

With the name of San Marzano the locality is mentioned in a deed of sale from 963 preserved in the Abbey of the Santissima Trinità in Cava de' Tirreni.

At the beginning of the seventeenth century it was a marquisate in the possession of the Mastrilli family and, together with the other communities of the valley, it was in dispute with Alfonso Piccolomini, count of Celano and feudal lord of Scafati, due to a dam on the Sarno river that he had built and which involved damage to local populations.

In 1903 the archaeologist Ettore Pais conducted an excavation campaign in the San Marzano area, which brought to light materials from the 9th-8th century BC.
