Grotta del Sole is a place for wine production. An ancient oriental legend has it that, after making his wine in a cave, a man had to go away for a while. He needed a guardian for the cave, so that no-one could drink the precious nectar and he chose the Sun, who could never enter the cave himself either.

This name is used to indicate the area where the winery is located, and where in 2006 a major archaeological discovery was made. a preventive excavation work next to the company site led to the finding of a Roman rural villa. Built between the late 2nd century b.C. and the early 1st century b.C., the building shows traces of different construction stages and following renovation work, which testify of its activity until the 4th-5th century AD. The finding of a torcularium and a wine cell in the villa suggests that the building was a centre where wine was made as well as sold. Starting from the 5th century AD the area was used as a burial place. 24 tombs of different types, of both children and adults, have been found along the walls of the building and the courtyard.
