Restored 1740s Fortress in Spain Built to Defend Against Pirates
Built in 1740 under the reign of the Spanish Bourbons, Castillo del Príncipe — or “Castle of the Prince” — stands on Galicia’s rugged Costa da Morte, its thick granite walls once guarding the Corcubión estuary from pirate invasions.
The fortress was named in honor of the son of King Charles III of Spain and constructed alongside Castelo do Cardeal (“Castle of the Cardinal”) across the water. Together, the twin strongholds protected the coastline from seaborne threats. Local lore tells of a massive iron chain hidden beneath the waves, connecting the two fortresses and raised to block enemy ships as they advanced — a story that has become part of Galician maritime legend.
Originally state property, the fortress was sold at public auction in the late 19th century. In 1985, Galician businessman Xosé Ramón Oreiro undertook a major restoration, transforming the historic stronghold into a private residence while maintaining its architectural integrity.
Today, the property spans over 1,900 square meters (more than 20,400 square feet) with nine bedrooms arranged around a vast central courtyard. The former garrison quarters — once home to 88 soldiers — have been reimagined with vaulted ceilings, stained glass windows, and pointed arches that flood the interiors with natural light. Original defensive features remain visible throughout, from the half-bastions of the ravelin to the outer moat and stone bridge leading to the heart of the compound.
Set on approximately 8.2 acres overlooking the Atlantic, the horseshoe-shaped fortress commands sweeping views of the sea and surrounding forests. The granite masonry, carved with remarkable precision, reflects the craftsmanship typical of 18th-century military architecture in Galicia — austere, monumental, and enduring.
Designated a Site of Cultural Interest in 1994, Castillo del Príncipe forms part of Galicia’s protected cultural heritage. Its restoration balances historical preservation with discreet modern comfort, offering an exceptional opportunity to own one of Spain’s most singular coastal properties — a residence born from the need to defend the empire’s western edge, now reimagined as a private retreat on the “Coast of Death.”
