It is very likely that the Greeks of Focea and Elea (Velia) traveled all over the territory of today's Municipality of Ceraso in climbing to the Terre Rosse and the Beta pass.
And it is not to be excluded that some of them, in search of good wood to feed the shipyard of Velia, stopped, and then held back, on the large river terrace (river Palisco = mountain, today Palistro) at the mouth of which it was the northern port of Velia. A place that appeared to them very charming, seen from the top of the Tempe, rich as it was in cherry trees of the genus prunus. A terrace surrounded by long-standing tall trees.
They certainly stayed there when the locality became an important road junction. In fact, the fluvial road, the road along the Palistro, reached it; a short distance from that place passed the road to the Terre Rosse; from there the easy way started which, by today's Coste delle monache, led to the Alfa pass (Cannalonga) and from there into the Vallo di Diano.
However, it is certain that in the early Middle Ages the inhabited area in the place must have been particularly flourishing if in ancient documents it was indicated to locate nearby settlements.
A parchment dated 6 May 1149 by Pope Eugene III recognizes the monastery of Santa Barbara as “ubi Cerasus dicitur” (where it is called Ceraso) to the abbey of Cava. News confirmed by another of Pope Alexander II a few years later in January 1168.
The inhabited area also expanded due to its happy geographical position, in the center of the towns that were then to build its hamlets in the Napoleonic era, when the town was chosen as the capital of the Municipality. An important agricultural center, due to its very fertile alluvial soils, the town continued to develop gradually, achieving a singular building increase in recent years. This was determined by the improved economic conditions of the population which allowed not only the renovation of the old houses, equipping them with useful modern structures, but also allowed the construction of new housing, especially single-family homes.
