Solfara Cozzo Disi, Sulfur mine in Casteltermini, Sicily, Italy.
Solfara Cozzo Disi is a sulfur mine in Casteltermini with multiple underground levels along the Platani Valley, featuring extraction tunnels and processing facilities. The site extends across different depths with well-preserved structures from its operating period.
The mine operated before 1839 on Monte Lungo in the Chipirdia feudal lands and remained active until its closure in 1988 under Regional Law 34. For nearly 150 years it was a key raw material supplier for the Sicily region.
The site shows Sicily's industrial past through preserved mining equipment and machinery from different working periods. You can see how miners lived and worked underground.
The mine museum offers guided tours with safety equipment to explore sections of the underground tunnels and mining installations. Visitors should wear comfortable clothing and prepare for varying temperatures underground.
In 1916, one of Europe's worst mining disasters occurred here when tunnel collapses and hydrogen sulfide emissions caused the deaths of many workers. This tragic event remains an important part of Sicily's mining history.
