Cava Usai – A Historic Site Ready to Reemerge as an Exclusive Residence

In one of the most captivating and unspoiled areas of Sardinia’s southeastern coast, within the Capo Carbonara Marine Protected Area, lies this remarkable seafront property nestled in the evocative landscape of Cava Usai—an old granite quarry dating back to the 19th century. Operational until the 1950s, this quarry supplied materials for significant public works, including the port of Naples, the historic roads of Cagliari, and constructions on the island of Malta. Today, the remnants of the original structures—the main house and the custodian’s dwelling—bear witness to a storied past and harmonize with the natural surroundings of time-worn rocks, pale gravel, and crystalline turquoise waters. The property spans approximately five hectares, including around 800 metres of seafront. On the grounds stand two buildings in need of restoration: the main building, spread over two levels totaling around 300 m², and a dependence covering approximately 85 m². Both structures enjoy a rare and unique location, offering an exceptional foundation for a restoration project with truly distinctive character. Among the potential development opportunities is the possibility to build a swimming pool, harmoniously integrated into the natural surroundings, as well as to restore the historic pier once used for motorboats, which in the past provided direct sea access for the transport of granite. Adjacent to the property is Cava Usai beach—a small cove of sand and gravel, framed by impressive granite formations that create an untouched and seldom-visited natural environment. The absence of tourist infrastructure makes this area ideal for those seeking tranquility, privacy, and an authentic connection with nature. At the top of the promontory, within the property, rises the 16th-century Spanish coastal Torre di Porto Giunco. Approximately nine metres tall and perched fifty metres above sea level, the tower dominates the surrounding landscape and offers breathtaking views of the islands of Serpentara and dei Cavoli, as well as the cove below. A simple, well-marked panoramic path connects Porto Giunco to Cava Usai, making the property accessible on foot via a short and pleasant 20-minute walk. This property represents a rare opportunity on the market: an authentic, history-rich location where one can develop an exclusive architectural project amid a protected, extraordinarily charming landscape.
