A Portuguese sailor claims to have discovered a large underwater pyramid, between the islands of Sao Miguel and Terceira, in the Azores.
Diocleciano Silva couldn't believe what his eyes were telling him. As he was sailing in the Atlantic Ocean looking for fish, he spotted a perfectly-shaped pyramid structure on the sonar.
After checking the GPS devices and maps again, Silva confirmed that the unknown underwater construction was lying at 40 meters (131 feet). Square, and aligned with the four cardinal compass directions. The pyramid's base is estimated to have 8000 square meters.
The strange discovery was reported to the Portuguese Hydrographic Institute. Could it be an old civilization, a volcanic construction, the effects of ice age glaciation?
