Archeologists from the Portuguese Association of Archeological Research (APIA) have identified new archeological evidence on Pico island that supports their belief that human occupation of the Azores predates the arrival of the Portuguese by many thousands of years.
The new evidence comprises of a great variety of protohistoric pyramidal rock structures, some of them 13 meters tall. The Azorean archipelago was discovered by the Portuguese around 1427.
Archeologists working on site believe the structures were created by ancestral occupiers of the island suggesting they were places of worship with funeral ritual purposes. They have said that dozens of similar structures have been identified in the Madalena area of Pico island.
