CADIZ, Spain – An archaeologist named Michael Donnellan announced a discovery that he believes could be the legendary lost city of Atlantis. Donnellan asserted that he found submerged structures off the coast of Cádiz, Spain, which correspond closely with the descriptions given by the ancient Greek philosopher Plato.

At a recent conference titled the Cosmic Summit in North Carolinan presented videos and scans indicating a network of circular formations on the ocean floor. He believes these submerged structures are the remnants of Atlantis, as detailed in Plato’s works Timaeus and Critias.

Over the past eight years, Donnellan’s team conducted extensive research along the coastline near Cádiz, employing sonar and LiDAR technology. This research uncovered long, intersecting linear structures forming enormous concentric circular walls standing over six meters high. “We discovered long, linear structures intersecting on the seabed,” said Donnellan.

He explained that the outer wall appeared to have suffered major destruction, potentially due to a massive tsunami, while the inner walls were displaced and split into two parts. “The inner second and third walls were completely displaced and split in two,” Donnellan noted.

At the center of these concentric rings, the team identified a rectangular ruin that Donnellan believes corresponds to the Temple of Poseidon described by Plato. “The layout matches perfectly with Plato’s descriptions,” said Donnellan.

In a documentary featuring their work, Donnellan and his colleagues were seen diving in turbid waters, claiming to come “face to face” with the first wall of the structure. They reported that the underwater formations exhibited sharp right angles, flat surfaces, and uniform thickness several feet thick. “Upon observation, clearly cut stones are seen stacked one on top of the other,” said Donnellan.

He asserted that the arrangement of the walls is too orderly to be of natural origin, suggesting intentional human construction.

Donnellan believes that these findings support the existence of Atlantis as portrayed by Plato, proposing that this civilization sank into the ocean approximately 11,600 years ago due to a great catastrophe, possibly associated with the Younger Dryas climatic event. “Plato puts it very well; he says that this happened in a night of earthquakes and floods,” said Donnellan.

The Younger Dryas period was a time of global climate change, and some researchers suggest could have led to the demise of an advanced prehistoric civilization.

Donnellan’s interpretation of the location of Atlantis aligns with Plato’s descriptions, placing the island civilization west of the Pillars of Hercules, known today as the Strait of Gibraltar. He recalled that Plato mentioned Atlantis was located near ancient Gades, now known as Cádiz, the oldest city in Western Europe. “They match exactly with Plato’s description,” insisted Donnellan,.

Donnellan has yet to convince the entire scientific community. “Perhaps we should now speak of an ancient Atlantic culture. It’s easier to believe when the evidence speaks for itself,” he said.

Donnellan and his team conducted more than 20 dives, uncovering new evidence such as collapsed walls, artificial canals, and huge stones that appeared to have been violently displaced from their original positions. Among the discoveries were large rectangular stones with dimensions comparable to half the size of a small car.

He mentioned that the dimensions of the submerged city closely correspond to the 3,000 by 2,000 stadia mentioned by Plato, which is approximately 341 by 227 miles—the size of the state of Nevada in the United States.

The Daily Mail, and AOL reported on the finding, among other news publications.
