Terceira: Pyramidal structure found by amateur sailor not man-made – Azores

An underwater pyramidal shaped structure identified by amateur sailor Diocleciano Silva, at a depth of 40 meters off the coast of Terceira Island, most likely ”not man-made,” according to Portuguese Navy bathymetry experts.

The structure found by Silva had been previously documented by the Portuguese Navy and was known to bathymetric researchers – they said. It lays near the Bank of João de Castro, between the islands of Terceira and São Miguel.

There is no scientific data to confirm the origin of the structure, but it could have been formed by a volcanic eruption – experts have said. The archipelago of the Azores is composed of nine volcanic islands.

According to the bathymetric data collected by Silva, the structure is about 60 meters-tall with a base measuring 8,000 sq m. Silva believes the structure is man-made.

In recent years, archaeologists from the Portuguese Association of Archaeological Research (APIA) have identified archaeological evidence on all the Azorean islands that supports their belief that human occupation of the Azores predates the arrival of the Portuguese by many thousands of years.

The Azores archipelago was discovered uninhabited by the Portuguese around 1427.
