In the heart of Salento, among the olive groves and countryside surrounding Nardò, lies one of the most enigmatic and fascinating sites in Puglia: the so-called Arneo Rings. This vast complex of concentric structures, mainly visible from above, has attracted the attention of archaeologists, geologists and enthusiasts of the region’s history.

Their almost perfect, geometric shape recalls the ancient description of Atlantis, the mythical city of concentric rings of land and water described by Plato. Hence the nickname that has accompanied the site for years: the Salento Atlantis.

A discovery born from an intuition

The site was officially reported by Oreste Caroppo, a Salento scholar and environmentalist, who in 2012, while examining aerial photographs from the National Geoportal, noticed large circular formations in the ground between Masseria Santa Chiara and Masseria Maramonti, in the territory of Nardò, a few kilometers from Torre Lapillo.

Fascinated by these shapes, Caroppo decided to carry out a field inspection in 2019. It was then that he identified ceramic fragments, bones and a handle from a perforated spindle-shaped vessel, all elements suggesting very ancient human activity, dating between the Bronze Age and the Iron Age.

The dark-colored soil, typical of many protohistoric sites in Salento, together with the concentric arrangement of the structures, led Caroppo to hypothesize that the site may have been an ancient village or settlement, possibly fortified, inhabited for centuries and eventually abandoned.

A landscape of circles and memories

The rings extend across more than two square kilometers and, in some cases, exceed 100 meters in diameter. They consist of earthworks and, probably, concentric ditches that once enclosed internal areas and can still be identified today through variations in the color and texture of the soil.

Their remarkably regular organization, together with the presence of ancient road traces and the route of the old Via Traiana Salentina, suggests that the area may have been a strategic hub within communication and trading networks connecting the coast with the inland territories.

A local resident whom Caroppo met during his field inspection confirmed that the dirt road running alongside the rings is still known locally as “the Roman Via Traiana”, a section of the ancient route connecting Nardò with Avetrana and passing through the Arneo area.

A landscape between history and myth

The most fascinating hypothesis is that the Arneo Rings may correspond to the ancient Messapian city of Graxa (ΓΡΑΧΑ), represented on the famous Soleto Map, dating from the 6th–5th century BC and considered one of the oldest known maps depicting Salento.

If this interpretation were confirmed, the Arneo site would represent one of the rare places where archaeology, ancient place names and historical geography converge, documenting the continuity between coastal settlements—such as Scalo di Furno and Li Schiavoni—and the inland areas of Salento.

At Scalo di Furno itself, just 3.5 kilometers from the site, excavations carried out in the 1960s uncovered Mycenaean pottery, votive figurines, evidence of animal sacrifices and a fragment bearing the Messapian name “Thana”, identified with the goddess Diana or Athena.

The proximity of these sites strengthens the idea that Arneo may have formed part of a wider system of protohistoric settlements with defensive, ritual and commercial functions, distributed along the Ionian coast.

The Salento Atlantis: a symbolic vision

The comparison with Atlantis is not merely evocative, but also symbolic. Plato describes the lost city as a place of harmony, built around concentric circles of land and water, with a sacred center dedicated to Poseidon.

Although the Arneo Rings have no visible water channels, they display a geometric and potentially symbolic layout that is strikingly reminiscent of this concept: a circular arrangement that may have represented the cosmos, the community or political power. Some interpretations suggest that the different concentric zones may have separated residential areas, ceremonial spaces and productive activities.

As Caroppo wrote in his report:

“Did we then have, to nourish our imagination, an archaic Salento Atlantis hidden there beneath a vast expanse of cultivated land?”

It is a powerful image that perfectly captures the mystery and fascination surrounding the site.

A threatened heritage

Despite its historical and landscape value, the Arneo Rings area is currently threatened by plans for industrial photovoltaic installations that would cover approximately 100 hectares of land.

The construction of solar panels and related infrastructure could irreversibly compromise archaeological traces preserved beneath the soil, potentially undermining years of research and investigation.

Caroppo and numerous scholars have therefore issued a clear appeal: protect and enhance the area as a site of archaeological and scientific interest, incorporating it into shared protection and research initiatives involving local communities.

Such an approach would represent an act of cultural responsibility and collective memory, bringing historical research together with genuine environmental sustainability, beyond purely speculative interests.

A laboratory of history and landscape

The Arneo Rings are not simply remnants of a distant past: they are a window into the ancient relationship between people and their environment, into the territorial organization of protohistoric communities and into the cultural continuity of Salento.

They represent a living laboratory where science meets myth, where the land reveals its layers of history and where the sky mirrors the geometry of long-lost circles.

Preserving them means protecting a unique heritage, a testament to humanity’s ability to shape space according to both functional and symbolic principles.

The “Salento Atlantis” has not disappeared.

It is simply waiting to be recognized, studied and restored to its place in history.
