A submerged pyramid-shaped mound has been detected by a sailor in the waters off the Azores islands.
The structure, which was discovered using a GPS type device, is believed to measure 60 metres in height and a base covering 8,000sqm.
It was discovered by sailor Diocleciano Silva after a bathymetric survey of the area to assess underwater depth.
The finding is now being investigated by the Portuguese Navy at the request of the Azorean Regional Government.
Although many would like to believe that the lost city of Atlantis had finally been found, the Portuguese Navy suspects the sailor may have detected the D. João de Castro Bank, a large submarine volcano located between the Azorean islands of São Miguel and Terceira.
