Within the conservation of cultural heritage, this contribution focuses on the system of ancient rock-cut churches scattered throughout the countryside of Erice, which are now primarily in ruins. Special attention has been given to certain artifacts located on the western slope, dating back to the thirteenth century, namely Santa Maria Maggiore, Sant'Ippolito, and Santa Maria Maddalena. These churches are well known to visitors of the numerous hiking trails and are situated near the ancient access road to the city, which also leads to the village of Bonagia, the city of Trapani, and other sites in the valley. Their construction is part of the extensive process of re-Christianization of the island that began after the Norman reconquest, characterized by a rapid flourishing of monasteries that still bear traces of the precious Byzantine iconographic repertoire influencing most Sicilian monuments, from grand cathedrals to humble rural churches. The absence of a systematic approach to the preservation of monuments and sites is leading to the loss of important artistic and architectural witnesses of the medieval history of this area. In light of documentary and archival sources, the aim is to develop a critical and historical profile of local architecture. With the aid of modern surveys and digital drawing tools, content suitable for a diverse audience has been created, enhancing and promoting the cultural architectural heritage of the Erice area.
