Equally, the fertility of the surrounding land prompted the establishment of a feudal estate in 1761 by Duke Placido Notarbartolo, on the site of the former hamlet of San Giacomo di Bambinetto, which had been destroyed in the 1693 earthquake. Villarosa’s early development was thus driven by the need to cultivate the Notarbartolo family’s extensive landholdings.
Its later expansion was fuelled by the growing demand for labour in the many sulphur mines that flourished in the surrounding area. The town’s urban layout was based on the Roman castrum model, with the intersection of its main roads inspired by the two major axes of 17th-century Palermo. It was designed by Rosa Ciotti, a painter from Caltanissetta, after whom the town was likely named.
While some aspects evolved, the town however retained the typical appearance of an agricultural centre in the Sicilian hinterland, dominated by the Mother Church. Housing was arranged to reflect social hierarchies, with the bourgeoisie occupying homes closest to the two main roads and the working classes living in the more peripheral areas.
The opening of the Garciulla mine in 1827 marked the beginning of the documented history of the sulphur industry in Villarosa, transforming the town into a mining centre. Alongside Garciulla, other mines such as Respica-Pagliarello, Gaspa La Torre-Villapriolo, Agnalleria and Santo Padre contributed to this transformation. The sulphur mines profoundly reshaped the landscape, at the same time digging into the social fabric and marking the childhoods of the carusi, young boys exploited in the harsh extraction efforts. Open-air furnaces known as calcheroni, and later Gill furnaces, left scars on the land still visible today as depressions or accumulations of reddish slag. Transporting raw minerals and molten sulphur required infrastructure such as narrow-gauge railways. In the early 20th century, the British built the Sikelia mining railway to carry sulphur to the ports of Licata Mare, Porto Empedocle and Catania Centrale. The route began at the Respica-Pagliarello mine, crossed what is now the Morello reservoir, and ended at Villarosa station. In the 1960s, this same station became the departure point for thousands of emigrants from Villarosa and surrounding areas, heading to northern Italy, Belgium, France and Germany in search of work and a better life.
In the 1970s, the town underwent profound changes with the damming of the Morello River and the construction of the Ferrara Dam, built between 1969 and 1972 by the Sicilian Mining Authority for industrial purposes. Its waters were used to wash and process potassium salts extracted from the Pasquasia mine, which ceased operations in 1995. The lake was initially created to support mining activity, and later its waters were repurposed for irrigation. The construction of the lake erased all traces of the Sikelia mining railway that once crossed the area.
Today, the Lake Morello area is part of a nature reserve of considerable ecological interest, especially for its wildlife. The Villarosa sulphur mines are now completely abandoned, their geological legacy enduring in the clay hills and the gorges carved by streams with brackish water, a result of evaporite deposits. The remnants of mining infrastructure stand as silent witnesses to this recent past, offering insight into the landscape, traditions and deep-rooted identity of Villarosa. The opening and closing of the mines shaped the town’s demographic and economic rhythms, leaving behind a complex legacy of hardship and separation.
