Tagomago: The Island That Remembers
There is an island you can see from the shore but cannot touch.
Just 900 metres off the northeast coast of Ibiza, Tagomago rises from the sea — rocky, rugged, and intensely private. It has no beach bars. No sunbeds. No crowds. It is, in the most elemental sense, a place the modern world forgot to ruin.
And that forgetting is exactly why it matters.
A note on access: Tagomago is entirely privately owned — one of the very few private islands in Spanish waters. It is not open to the public. The only way to set foot on its shores is to rent the island in its entirety, which starts at around €130,000 per week. The waters around it, however — and the posidonia beneath them — belong to the sea. And the sea belongs to all of us.
A Name Born from Antiquity
The etymology of Tagomago likely traces back to "rock Mago," a reference to Mago Barca, brother of the Carthaginian general Hannibal. In the Muslim era, the island was known as Taj Umayu. Long before the villa, before the lighthouse, before the yachts anchoring offshore, this small strip of land was already a landmark — a point of orientation for those crossing the Mediterranean.
The Tagomago lighthouse, erected in 1913, continues to serve as a reference point on the naval routes linking Ibiza with Palma de Mallorca and Barcelona. Before it was automated in 1963, a lighthouse keeper lived here alone. Imagine that solitude. Imagine what he protected without even knowing it.
A Living Nature Reserve
Tagomago is not simply beautiful. It is biologically extraordinary.
The island belongs to the Marine Reserve of the northeast coast of Ibiza-Tagomago — a marine area of high ecological and fishing value. Its cliffs and waters shelter some of the Mediterranean's most endangered creatures.
Tagomago hosts 200 breeding pairs of critically endangered Balearic shearwaters, Europe's most threatened seabird. Eleonora's falcons nest in the island's cliffs, loggerhead sea turtles (Caretta caretta) move through its waters, and an endemic subspecies of lizard — Podarcis pityusensis tagomagensis — exists nowhere else on Earth.
Read that again: nowhere else on Earth.
Tagomago has been designated as a Special Protection Area for birds and carries Marine Reserve status, which legally prevents development or public access — a conservation framework that guarantees the island remains exactly as nature intended.
Beneath the Surface: The World of Posidonia
If Tagomago is magnificent above the waterline, it is nothing short of sacred below it.
The crystal-clear waters surrounding the island are home to dense meadows of Posidonia oceanica — the ancient seagrass that makes Ibiza unlike anywhere else on the planet. The Posidonia meadows around Ibiza are defined as the best preserved in the entire Mediterranean. They are not algae, not seaweed. Posidonia is a true flowering plant, endemic to the Mediterranean Sea, forming vast underwater meadows of extraordinary ecological importance.
The meadow between Ibiza and Formentera is one of the largest and oldest living organisms on the entire planet — more than eight kilometres long and estimated to be over 100,000 years old.
One hundred thousand years.
When you dive beneath the surface near Tagomago and glide over those long, ribbon-like green leaves swaying in the current — as we did when photographing the Molly Estelle for this season's campaign — you are swimming over something that was already ancient when the Phoenicians first arrived on these shores.
What Posidonia Actually Does
The posidonia meadows are not just beautiful. They are the engine of everything you love about Ibiza's sea.
Seagrass can absorb around 15 times more carbon per hectare per year than the Amazon rainforest. A single square metre of posidonia meadow can produce 14 litres of oxygen per day, and approximately 1,000 different species of animals live within these meadows, finding shelter and food.
One hectare of posidonia produces 21 tonnes of biomass per year — comparable to the productivity of a tropical rainforest. The meadows purify coastal waters by retaining sediments and oxygenating the sea, stabilise beaches, buffer the coast from storms, and serve as nurseries for many varieties of fish.
That impossible turquoise water you photograph every summer? Posidonia made it.
A Plant Under Pressure
To know something this precious is to understand the urgency of protecting it.
Over the past 40 years, the western Mediterranean has lost about a third of its posidonia meadows. The warming of the seas poses a major threat — seagrass begins to die off once water temperature reaches 28°C, something that now happens every summer.
Posidonia grows at a rate of less than one centimetre a year. A single vessel dropping anchor in the meadow can create a bare patch that takes centuries to repair.
Because it is slow-growing — with just one square metre taking up to 100 years to generate — this loss could have a serious, irreversible impact.
What We Can All Do
If you are visiting Ibiza by boat, ask your captain to use the Posidonia MAPS app (available free on iOS and Android), which provides real-time guidance on where not to anchor. Support IbizaPreservation at ibizapreservation.org — they fund the mapping, the science, and the advocacy that keeps these meadows alive.
And when you see those brown leaves lining the shore in autumn and winter? Leave them. Even when dead, posidonia still fulfils an important function, protecting beaches against erosion.
The Thread We Carry
At Deessa, Tagomago is more than a backdrop. It is a reminder of what we are working toward.
Every piece in our collection made from regenerated nylon — reclaimed from ghost nets and ocean waste — exists because places like this exist. Because the posidonia is real. Because the shearwater is real. Because the lizard found nowhere else on Earth is real.
Fashion cannot save an island. But it can stop adding to the damage. It can choose differently. It can be made from what the ocean gives back, so the ocean can keep giving.
The sea has been here for 100,000 years.
We intend to honour that.
