Rice Terraces of the Philippines Cordilleras

The Banaue Rice Terraces are terraces that were carved into the mountains of Banaue, Ifugao, in the Philippines, by the ancestors of the Igorot people. The terraces are occasionally called the "Eighth Wonder of the World". It is commonly thought that the terraces were built with minimal equipment, largely by hand. The terraces are located approximately 1,500 metres above sea level.
