Due to its strategic position, Assoro’s history is marked by successive dominations: after the Greeks, Romans and Carthaginians, it endured the Norman conquest and resisted the Muslim invasion. The area has yielded valuable archaeological finds, including Hellenic and Roman remains, also discovered in the surrounding countryside. There must once have been a vast self-sufficient medieval estate (known as a curtis), comprising elegant villas used both for leisure and for managing the region’s fertile lands.
The central square offers panoramic views of the ancient Abbey of Santa Chiara complex, which was founded in the 15th century by Virginia Valguarnera. The old town has remained faithful to its original layout and is notable for its homogeneous architecture and well-preserved buildings. Among these buildings, the Palazzo della Signoria is particularly noteworthy. Commissioned by the Valguarnera nobles in 1492, it features rusticated portals and finely crafted stone balconies, and is connected to the Basilica of San Leone by an arched passageway. The basilica is a wonderful example of Gothic architecture, enriched by Arabic and Catalan influences.
Another important site is the Convent of Santa Maria degli Angeli, recently renovated and transformed into a museum for exhibitions, cultural events and receptions. The museum’s collections are arranged chronologically, spanning from contemporary art to ancient artefacts. They include works by Elio Romano, who captures the charm of the Morra Valley, traversed by a thousand-year-old road lined with sanctuaries. This sacred route was once followed by pilgrims from the Rocca di Cerere to venerate the Saint of Agira, and it reflects a centuries-old tradition of sulphur mining in Assoro.
The museum also explores the historical and literary connections linked to the sulphur mines, the peasant civilisation of inland Sicily and themes of archaeology and myth. These include the tale of Crisa, the river god who personifies the ancient river of the same name – now called the Dittaino – and Ceres, who, according to some versions of the myth, passed through the Morra district on her way to the slopes of Mount Etna, the realm of the Underworld, in search of her daughter kidnapped by Pluto.
On the modern road leading to the castle, there is a small cave, likely a protohistoric tomb, which was later converted into a rock church during the Byzantine period. It remains a place of worship today, with its walls adorned by several series of frescoes dedicated to the Madonna della Mercede.
The castle, perched on the highest point of the mountain, originally featured a central structure with a regular plan, parts of which are still visible. Its fortifications masterfully blend volumes carved into the rock with solid masonry construction. Surviving elements include a large curtain wall ending in a circular tower, a second tower with windows overlooking the valley, and an underground passageway.
Assoro’s history is closely linked to the sulphur mining industry, with its decline after World War II until the final closure of the mines in the 1990s. However, the presence of scattered mining sites remains an important part of the local identity and represents a recent past that must not be forgotten.
Today, all that remains of this world are ruins and relics: the rooms with powerful winches that hoisted cages filled with minerals, miners and carts; the workshops where tools were repaired and maintained; the small churches adorned with images of Santa Barbara, patron saint of miners; the lamp rooms, electrical cabins, furnaces and settling tanks. There are also crumbling towers – striking structures erected at the mouths of wells plunging hundreds of metres deep, built to support the pulleys that turned the ropes – as well as traces of calcaroni (large smelting furnaces used to separate refined sulphur from impurities). Remnants of the railway and dark tunnels still linger, along with dilapidated toll booths, surviving signs of a slow rack railway system that once transported miners and has been out of service for decades.
However, what inevitably falls into oblivion is the harsh reality endured by generations of miners – the raw testimony of fathers who laboured naked and engulfed in darkness at the end of tunnels. They endured exhausting shifts under the command of their overseers, inundated with smoke that had devastating effects on their health. The tenderness once visible in the faces of the carusi – young boys forced to carry heavy sacks of sulphur, often weighing twice their own body weight – has faded. These children were mistreated and handed over by their families, who, driven by hunger, sent them to work in exchange for the so-called soccorso or anticipo morto: an advance payment given to the child’s family, which bound the boy to the miner until the debt was repaid (from https://conventodegliangeli.it/il-paesaggio-minerario).
