The Genoese tower of Campomoro seen from the sea

Standing on a granite headland battered by the waves, the tower of Campomoro is the most imposing of all the Genoese watchtowers in Corsica. Seen from the sea, this stone sentinel reveals its full power and its five centuries of history. On a boat trip from Propriano, discovering this landmark monument is a genuine highlight, blending heritage, emotion and the raw beauty of the coastline.

A fortress facing the sea: five centuries of history

The tower of Campomoro was erected around 1586 under the administration of the Republic of Genoa, which controlled Corsica at the time. It formed part of the vast network of coastal towers built during the 15th and 16th centuries to protect Corsica's shores from Barbary raids. These pirates from North Africa launched devastating attacks on coastal communities across the Mediterranean, pillaging villages, enslaving inhabitants and spreading terror.

To counter this threat, Genoa ordered the construction of a chain of watchtowers spaced so that each could communicate with the next by smoke signals during the day and fire at night. The tower of Campomoro held a position of major strategic importance: perched at the southern tip of the Valinco Gulf, it commanded a view across the entire gulf and out to open sea. Any suspicious vessel spotted from its summit could be signalled within minutes to neighbouring towers and to the villages inland.

Standing 17 metres tall with a base diameter of 11 metres, the Campomoro tower is the largest of all the surviving Genoese towers in Corsica. It surpasses in size and strength the better-known towers of Porto, Nonza and Ile-Rousse. This exceptional scale reflects the strategic value of the site: the Valinco Gulf formed a natural gateway into the Corsican interior.

The star-shaped enclosure: a unique defensive design

What truly sets the Campomoro tower apart from every other Genoese tower is its star-shaped fortified enclosure. This bastioned structure, added in the 17th century, is unique in Corsica. The points of the star face the most likely angles of attack, allowing defenders to deliver crossfire against any assailant attempting to approach the tower.

From the sea, this military architecture makes immediate sense. You can instantly understand why the designers chose this shape: the bastions jut out towards the maritime approaches, creating layered defences around the central cylindrical tower. The enclosure walls, over a metre thick, were pierced with loopholes for musket fire. The tower itself was equipped with cannons at its summit, covering the sea through a full 360 degrees.

The view from the water: a perspective like no other

Most visitors discover the Campomoro tower by land, after a short walk from the village. But it is from the sea that the monument reveals its true grandeur. The boat offers a view that the torregiani -- the tower's own guardians -- knew well: that of a mariner approaching the coast and catching sight of this mass of stone rising against the sky.

Approaching from the open water, the tower appears to grow from the very rock. The granite of its walls blends with the granite of the cliff, as though the building were a natural extension of the headland. This fusion of human architecture and geological landscape is one of the tower's most striking characteristics. The Genoese builders did not simply place a tower on a rock -- they made it part of the site.

Sailing past the foot of the tower is a moment of quiet contemplation. Passengers look up at the stone mass towering above them, absorbing the architectural achievement and the courage of the men who lived there, isolated against the sea, watching the horizon for months on end. The tower has been listed as a Historic Monument since 1992, in recognition of its outstanding heritage value.

The tower in its natural setting

The Campomoro tower does not exist in isolation: it sits within a coastal landscape of raw, wild beauty. The headland on which it stands is flanked by spectacular calanques with turquoise waters. The impenetrable, scented Corsican maquis wraps around the fortifications, creating a vivid contrast between the harshness of stone and the softness of vegetation.

The waters around the tower are rich in marine life. Boulders that have tumbled from the cliffs form an artificial reef colonised by abundant sea creatures and plants. Groupers, the gentle giants of the Mediterranean, have made their home in the crevices of these rocks. Brown meagres, recognisable by their dark colouring, patrol along the submerged walls. It is a remarkable snorkelling spot, easily combined with admiring the tower from the water.

The village of Campomoro, nestled in the bay facing the tower, is one of the last unspoilt coastal hamlets in southern Corsica. Seen from the boat, its handful of stone houses spread between a fine-sand beach and the first slopes of the maquis, offering an image of timeless, authentic Corsica.

The Genoese tower network of the Valinco

The Campomoro tower was not alone: it formed part of a visual communication network that spanned the entire Corsican coastline. Within the Valinco Gulf alone, several towers answered one another from north to south. During a coastal cruise, it is possible to spot several, piecing together the defensive web designed by the Genoese.

This network operated as a remarkably effective early-warning system. A suspicious ship sighted off Campomoro could be signalled to Ajaccio in under an hour through the chain of towers. Each tower housed a garrison of two to four men, the torregiani, who took turns to maintain a permanent watch. Their life, defined by solitude and vigilance, is one of the most fascinating aspects of Corsica's maritime history.

Today, these towers are silent witnesses to a bygone era. Yet they continue to punctuate the coastal landscape and to mark boat trips with stops steeped in history. Exploring the maritime heritage between Campomoro, Porto Pollo and Olmeto makes a perfect complement to visiting the tower.

Photographing the tower from the sea

The Campomoro tower is one of the most sought-after photographic subjects in southern Corsica. From the sea, the possibilities are endless and change with the angle of approach, the light and the state of the sea.

In the morning, the sun illuminates the tower's eastern face, bringing out warm tones in the granite against a pure blue sky. This is the ideal moment for high-contrast shots, with deep blue sea in the foreground and the pale mass of the tower set against the dark green maquis. In the late afternoon, the low-angled light sets the stonework alight and casts long shadows across the fortifications, creating a dramatic atmosphere.

Photographers particularly appreciate the low-angle view from water level, which accentuates the building's monumental presence. Framing the shot with submerged rocks in the foreground, crystal-clear water in the middle ground and the tower behind produces images of remarkable visual power. It is one of the best spots in the Valinco Gulf for photography.

Including the tower in your boat trip

The Genoese tower of Campomoro is an essential stop on any boat trip in the Valinco Gulf. It combines naturally with the Campomoro calanques and a swimming stop in the surrounding coves. The sail from Propriano lets you appreciate the evolving landscape, from the sheltered harbour to the wild southern coastline.

To enrich your discovery, consider extending the cruise southward towards the Senetosa lighthouse, or crossing the gulf to explore the northern coast towards Porto Pollo. Each section of shoreline offers its own wonders, and the Campomoro tower remains the central landmark, visible from almost every point in the gulf -- just as it was for the sailors of centuries past.
