Environments and nature
Le Saline Conti Vecchi, where salt tells the story of the meeting between people and nature.
Many people visiting the Conti Vecchi Saltworks for the first time arrive with the assumption that industry and nature belong to two separate worlds. On one side, there is human labor, production, and transformation. On the other, the landscape, silence, and biodiversity.
Then, as happened to us, you enter the Santa Gilla Lagoon, just a few kilometers from Cagliari, and that perceived distance begins to fade.
It happens as you watch the salt ponds change color beneath passing clouds, their hues shifting with the unique light of each season. It happens as flamingos glide across the water while, just a short distance away, the salt workers continue their daily tasks. And it happens as you listen to a story that began almost a century ago, when one man envisioned a place where economic development, human labor, and respect for the landscape could coexist.
The Conti Vecchi Saltworks are far more than the place where salt is produced. They tell the story of a meeting: between sea and land, between past and present, between the hand of humankind and the hand of nature. To truly understand it, we must return to the beginning—to a Tuscan engineer who, at an age when many people think about slowing down, chose instead to begin anew.
When we arrive, we step into the historic building, climb the staircase, and, to our right, cross a threshold that seems to carry us back in time. The original furnishings, the early twentieth-century cement tile floors, the atmosphere preserved almost exactly as it once was—we are standing in the office of engineer Luigi Conti Vecchi, the place where the ideas that would forever transform this land first took shape.
“Engineer Luigi Conti Vecchi was a Tuscan gentleman who made Sardinia his home. After serving as an executive with the Royal Railways of Sardinia, he decided, at the age of seventy, to build this modern saltworks on the outskirts of Cagliari”, explains Francesca Caldara, Head of FAI Heritage Sites in Sardinia.
He could have stopped. Behind him was a long and accomplished career, and he had reached an age when many people look back on what they have built rather than forward to what is still possible. Instead, he did the opposite: he looked ahead.
“He chose to build a saltworks here because he had fallen in love with Sardinia”, Francesca says. “He had this ambitious vision of restoring the area—a vast reclamation project for the entire Santa Gilla Lagoon”. In the lagoon, he saw what others had failed to imagine: a landscape long plagued by malaria that could become a source of work, progress, and a new relationship between people and the environment. The scale of the undertaking was extraordinary: reclaiming 2,700 hectares of land, creating the evaporation ponds and crystallization basins, and establishing what would become one of Europe's most important saltworks.
In his will, he left his children a single instruction: “Live according to nature”. As Francesca points out, those three simple words reveal how deeply that philosophy has continued to shape every decision made at the saltworks over the years.
But to truly understand Conti Vecchi's vision, numbers alone are not enough. You have to look at the people.
From the very beginning, Conti Vecchi envisioned a different kind of industry—one where work would not be separated from the lives of the people who made it possible every day. Alongside the saltworks, the village of Macchiareddu was established, a place that would soon become known simply as the Salt Community.
It was far more than a cluster of houses beside a workplace. It was a world of its own. Workers' homes stood alongside those of the managers, with a canteen, a school, and spaces for leisure and social life. There were tennis courts, bocce courts, and a dance hall where people gathered on Saturday evenings. Schoolteachers arrived each day by steamboat from Cagliari, while the parish priest traveled by horse-drawn carriage from Assemini to celebrate Sunday Mass. Two women from Carloforte ran the village grocery store, and every family was given a plot of land to grow fruit and vegetables—what today we would call an urban garden.
It was a community born from salt, but built on human relationships. “The Salt Community came into being—a vibrant, close-knit community, full of life”, Francesca recalls. Much of this history has been preserved through the memories of those who lived there. One of them is Giorgio Lecca, who was born in the Salt Community. The son of a Conti Vecchi driver, he attended the village school before spending fifty years at the saltworks, eventually becoming Director of Maintenance and Safety. His is both an ordinary and an extraordinary story—one that captures, better than any definition, what Conti Vecchi's vision was truly about. The saltworks were never meant simply to produce salt. They were meant to create opportunity.
When people think of a saltworks, they almost always picture the same scene: a vast white landscape stretching to the horizon. It only takes a short time here, however, to realize that white is just one of the many colors that define this place.
It is one of the first things you learn from Emanuele Masillo, a museum guide with FAI, who invites us to see the saltworks through a different lens.
“Whenever I bring visitors here, the first thing I ask them to do is pay attention to the colors”, he says. “Sometimes the colors of the saltworks are completely unexpected. The water can take on shades of purple, orange, and red. It's a spectacle that never ceases to amaze me”.
Emanuele still remembers the moment he realized he was witnessing something extraordinary: the first time he saw one of the crystallization ponds being emptied. Until then, he had imagined salt as a flat, uniform white surface, always the same. Then the water slowly receded, revealing a carpet of crystals beneath, reflecting the light so intensely that it was almost impossible to look at.
On days when the maestrale wind blows, Emanuele explains, the breeze lifts the white foam of magnesium sulfate from the highly concentrated waters and carries it onto the shrubs of the Mediterranean scrub. “It creates a landscape that looks almost wintry—almost like Christmas”, he says. Among those branches grows an unusual parasitic plant known as the Maltese mushroom, which, according to local legend, was brought here by the Knights for its reputed healing properties.
It is no coincidence that this landscape has become a haven for wildlife. Before seawater becomes salt, it passes through a long process of natural filtration. Along the way, it is purified enough to sustain fish, mollusks, small mammals, and, above all, birds, making this one of Sardinia's most important nature reserves.
The Conti Vecchi Saltworks are far more than a place where salt is produced. They are a living landscape—constantly changing, breathing, and continuing to surprise even those who experience it every day.
After learning to see the saltworks through different eyes, it is time to explore them. We climb aboard the little train with our guide, Marcella Balia, and within moments it becomes clear just how much more complex this place is than it first appears.
A succession of ever-changing landscapes unfolds before us: the crystallization ponds, where the water has reached the final stage of its journey and salt begins to take shape; the evaporation basins; the lagoon's Mediterranean vegetation; and the birds that have found their own delicate balance here.
“Salt production doesn't begin here. It begins with the sea,” Marcella explains as the train moves slowly forward.
Before it becomes salt, seawater embarks on a remarkable journey. It enters the saltworks and flows through seventeen evaporation basins before finally reaching the crystallization ponds. Along the way, it is constantly transformed: its salinity increases, minerals gradually settle to the bottom, and only what is needed continues toward the final stage. It is a system designed by human ingenuity, yet built in harmony with the laws of nature—a vast natural filtration process where nothing is forced and every step follows its own rhythm.
It is here, among the evaporation basins, that the landscape comes alive. Salicornia, or sea asparagus, flourishes here—a succulent plant that stores water, allowing it to thrive where little else can survive. And it is here that flamingos gather in the greatest numbers, their heads submerged, their legs moving rapidly through the water to stir up the mud. “They're feeding”, Marcella explains. “They move their feet to bring Artemia salina up to the surface”. This tiny brine shrimp makes up almost the entire diet of the flamingo, and it is thanks to this food source that the birds acquire their distinctive pink plumage.
The flamingos with fully developed pink-and-white plumage are adults; flamingos develop their full coloration only after two or three years. They all sleep facing the same direction. “They always sleep facing into the wind”, Marcella says, so simply watching them is enough to tell where the Mistral is blowing from. A little farther on, a solitary bird stands apart from the flock: a pied avocet, instantly recognizable by its slender bill, gracefully curved upward. Nearby, a yellow-legged gull carries a small orange spot on the tip of its bill. That spot is a signal for its chicks—the young birds before they are able to fend for themselves—which peck at it whenever they are hungry.
When the water finally reaches the crystallization ponds, the landscape changes once again. The basins that were once covered with water gradually turn into vast white expanses, fields that look as though they have been blanketed in snow. Marcella draws our attention to the contrasts: one pond still filled with water beside another already transformed into a brilliant white surface, ready for harvesting. Two different views of the same place, two moments in the same journey—and in between them, life continues to flourish, moving from one basin to the next.
Perhaps it is because salt is always within reach that we rarely stop to think about it. We use it every day. It finds its way into our kitchens and accompanies gestures so familiar that they seem almost effortless. Yet behind every grain lies a process that takes an entire year.
“It takes three hundred and sixty-five days to complete this process”, says Manuela Pillai, Events and Business Development Manager at the Conti Vecchi Saltworks.
We tend to think of production as something fast, immediate, and entirely controlled by human hands. Here, the opposite is true. People do not replace nature—they learn to work alongside it. During the first months of the year, the ponds lie dormant. Then seawater begins its journey once again, and from March onward a slow transformation unfolds, with every element playing its part: the sun drives evaporation, the wind guides the process, while the saltworkers observe, monitor, and intervene only when necessary.
“It's a perfect balance between the hand of man and the hand of nature”, Manuela explains. “Each contributes fifty percent”.
Here, the relationship between people and the environment is not one of domination but of collaboration: a deep understanding of the rhythms of this place, and the patience to work in harmony with them.
That is how it has been for almost a century. The water follows the same path, the sun and the wind continue to play their part, and the saltworkers keep reading the subtle signs of the saltworks, passing down a body of knowledge shaped by experience, observation, and time.
And sometimes, that knowledge is carried by a single sound.
Among the many things we rarely think about when it comes to salt, one is especially surprising: salt has a sound. During the crystallization process, salt slowly forms on the bottom of the ponds, layer by layer, until it is ready to be harvested. No instruments or measurements are needed to know when that moment has arrived. What matters is the knowledge of the people who live and work at the saltworks every day—those who have learned to recognize its subtle signs.
“The saltworkers stamp their feet on the surface to tell whether the salt is ready”, Manuela explains. “Among themselves, they ask, ‘Does it crackle?’ If it crackles, it's time”.
Perhaps it is at this stage of the year, with the harvest just around the corner, that the saltworks reveal one of their most beautiful sights. “The first crystals to form look like jewels”, Manuela says. Among them, one is especially rare: the delicate surface crystals known as flower of salt. Unlike the salt that settles on the bottom of the ponds, it forms as a delicate layer on the surface, appearing only in the early morning, and only when conditions are exactly right. It must be skimmed by hand with a fine net and collected immediately. Only a handful of saltworkers have mastered the technique, which is why its flavor is often described—without exaggeration—as surprisingly sweet.
It is one of those details that stays with you because it tells a story that goes far beyond the making of salt: a relationship shaped over time between people, wildlife, and the place they share. Some forms of knowledge can be learned from books; others can only be acquired by repeating the same gestures, day after day, and by noticing changes that would remain invisible to most people.
That is what makes the Conti Vecchi Saltworks so distinctive. They are not simply a place where people built something. They are a place where people learned to listen to the world around them.
By the end of the visit, the greatest surprise is realizing that the Conti Vecchi Saltworks are, once again, not quite what we thought they were. We have been here before. And yet, each return reveals something we had somehow missed: the light falling differently across the water, a story we had never heard before, an elegant black-winged stilt that, this time, we notice up close.
That is the secret of the saltworks: they never reveal themselves completely.
To walk through them again is to enter a place where everything carries a story of its own: an office preserved in time, a village that once thrived as a close-knit community, water that never stops changing color. And that is precisely what makes this place so extraordinary: it can never be confined to a single definition, not even by those who have visited before. They are industry, but they are also nature. They are production, but they are also memory. They are a place created to harvest salt, yet one that continues, even today, to preserve stories, landscapes, and the people who have shaped them—even for those who believed they had already seen it all.
