Built in 1955 at the initiative of the Sulphur Authority to provide a place of worship and spiritual comfort for the workers’ families, the church has a simple façade marked by a local stone portal and a small rose window that invites entry. It is dedicated to Saint Barbara, protector of miners. Inside, the single nave houses a Neo-Renaissance style limestone altar, enriched with votive offerings and mining tools hanging on the walls as tangible memories of the toil of the carusi and their fathers. The wooden statue of Saint Barbara, placed in a niche behind the presbytery, shows the saint with the palm of martyrdom and the tower, while simple stained-glass windows filter the light, creating a solemn and intimate atmosphere.
Every December 4, the community gathers for a mass dedicated to the saint. Each November 12, the miners’ day, a mass is celebrated in memory of the victims of the Gessolungo Mine, with the presence of local and regional authorities, military representatives, and citizens of Caltanissetta. The small churchyard offers views of the clay hills and the mouths of the disused Gill furnaces, silent witnesses of the 19th-century industrial epic that transformed this corner of Sicily into one of Europe’s major sulphur-producing areas.
