This story reminds me of the countless circular and rectangular features around Florida, the Straights of Florida, the Florida Keys, The Bahamas, Cuba, Haiti, Texas, California and the Caribbean.
The discovery of the ancient city of Akroteri on the island of Santorini was made by a local landowner who noticed numerous circular sink holes on his land. One day while inspecting his land, he fell into one of the sink holes and discovered the lost city of Akroteri below.
"Madrid - Where was the capital of Tartessos, the legendary pre-Roman civilization which once existed on the Iberian Peninsula?
The culture which flourished from around 800 to 500 BC is believed to have been located mainly around the present-day cities of Cadiz, Seville and Huelva in southern Spain, but no traces of a major urban settlement have been found.
Now, however, scientists have discovered surprising clues to where a major Tartessian city may have been, the daily El Pais reported.
Its ruins could lie in the subsoil of a marsh area known as the Marisma de Hinojos in the Donana National Park near Seville, according to the daily.
Chief researcher Sebastian Celestino declined to comment on the report. His team will give details once the investigation is finished, a representative of the Superior Council of Scientific Investigations (CSIC) told the Deutsche Presse-Agentur dpa.
For years, satellite and aerial images of the Marisma de Hinojos have revealed strange circular structures of different sizes - up to 200 metres in diameter - and rectangular forms.
The area is under water in wintertime, and until now, scientists had thought it had always been inundated.
That had made most of them skeptical of the possibility that the forms visible from the air could be remains of a human settlement buried in the subsoil.
Yet new evidence has now emerged, with electro-magnetic tests indicating that the area may have experienced long dry periods, according to El Pais."
