The Diagramma Studioeffe Art Gallery has hosted and continues to host art exhibitions, including international ones, in addition to the vast production of works and sculptures by Fornaro himself and his daughters. It is located in an ancient hypogean oil mill, one of the few still accessible in the area after various renovations.
Documented evidence of the oil mill dates back to the Catasto Onciario of 1753, which records its use as a “trappeto for grinding olives, outside the city walls in the place known as li Cameni.” The original millstone is still preserved, along with the grooves left by the presses, the niches where the workers rested, and the fossils embedded in the rock that date the cave to 500 million years ago.
