Archeologists from the Portuguese Association of Archeological Research (APIA) have identified archeological evidence on the Azorean archipelago that supports their belief that human occupation of the Azores predates the arrival of the Portuguese by many thousands of years, possibly even of a Carthaginian or Atlantean civilization.
The Archipelago of the Azores is composed of nine volcanic islands situated in the North Atlantic Ocean, and is located about 1,500 km west of Lisbon and about 1,900 km southeast of Newfoundland. Wikipedia
