Amid the quiet of the Iblean coastline, where the wind caresses the stone and the sea whispers ancient tales, stands the majestic skeleton of an industrial past: the Fornace Penna. Often referred to as a “Cathedral by the Sea”, this abandoned factory is one of the most striking examples of industrial archaeology in Southern Italy. Immortalized in the popular TV series Inspector Montalbano under the name “Mannara” the furnace carries a timeless charm, tied to its once-thriving production and the enduring mystery of its sudden destruction.
Location and Geographic Context
Fornace Penna is located in the Pisciotto district, a stunning stretch of coast between Sampieri—a seaside village in the municipality of Scicli—and Marina di Modica. Its position is nothing short of spectacular: perched on a promontory just meters from the sea, offering breathtaking views and steeped in both historical and cultural resonance.
Origins and Construction
The Fornace Penna was built between 1909 and 1912, commissioned by Baron Guglielmo Penna, a visionary entrepreneur who aimed to create a cutting-edge industrial hub for the time. The project was entrusted to engineer Ignazio Emmolo from Noto, who had degrees in mathematics from Catania and civil engineering from Naples. Emmolo traveled to Germany to study the advanced sixteen-chamber Hoffmann kilns firsthand. Upon his return, he faithfully replicated the German technical and engineering solutions, adapting them to the local context and using materials like regional limestone.
The location in Pisciotto was chosen with strategic precision: deep coastal waters allowed ships to dock and transport bricks, a nearby railway ensured land connections, a clay quarry just 200 meters away supplied the raw material, and a local karst spring provided the water needed for production.
Architecture and Structure
The factory complex was monumental in scale, built entirely of local limestone, giving it a solemn and almost sacred appearance. The two-story building featured a striking facade with a rhythmic sequence of arches and windows, creating a visually harmonious design. At its core was a sixteen-chamber Hoffmann kiln—an engineering marvel that enabled continuous brick production by rotating the firing chambers. Each chamber had its own ventilation and exhaust system, ensuring even baking and significant energy efficiency.
Alongside the kiln were numerous warehouses for storing bricks, administrative offices, workers’ dormitories, and a majestic 40-meter-tall octagonal chimney—an emblem of industrial progress. An internal track system and a Decauville ramp facilitated the movement of raw and finished materials throughout the plant.
Production and Economic Impact
During its years of operation, the Fornace Penna was a key economic driver for the Ragusa area. Over one hundred workers were employed there, producing bricks and construction materials for both local use and export, especially to Malta and Libya. The site was not only technologically advanced, but also a pioneering model of modern industry in Southern Italy.
The 1924 Fire and Its Aftermath
On January 26, 1924, a fire—almost certainly arson—devastated much of the factory. Fueled by the flammable materials used in production, the blaze quickly consumed the structure. Despite efforts to save it, the fire marked the end of the furnace’s industrial activity. The exact cause was never fully determined, adding an air of mystery and leaving the site abandoned for over a century.
Cultural Significance
Over the years, Fornace Penna has become far more than just an abandoned factory. It is now recognized as a site of historical and cultural importance and has been included among the “Places of the Heart” by FAI (the Italian National Trust), which has spearheaded awareness campaigns for its preservation. In 2024, the Sicilian Region officially expropriated the site, awarding compensation of €534,000 to the 26 heirs.
Its fame reached beyond the local level thanks to the Inspector Montalbano TV series, where it appears as the infamous Mannara—a dark, evocative place that encapsulates a Sicily both ancient and modern. The furnace features in several episodes, including “The Shape of Water“, serving as the backdrop for investigations steeped in mystery. The choice of this location was no coincidence: its majestic ruins and secluded cliffside setting at Punta Pisciotto create the perfect atmosphere for Montalbano’s tales. This media exposure has made Fornace Penna a must-visit destination for fans of the series and lovers of cultural tourism alike.
Current Status and Restoration Plans
After decades of neglect, the Sicilian Region’s 2024 expropriation has finally paved the way for restoration and redevelopment. Public funds have been allocated to secure the site and launch a recovery project aimed at restoring dignity and new life to this extraordinary example of industrial heritage. Initial work includes site cleanup and stabilization of the remaining structures, with the long-term goal of opening a museum or cultural center to the public.
