The Banaue Rice Terraces (Tagalog: "Hagdan-hagdang Palayan ng Banaue") are 2,000- to 3,000-year-old terraces that were carved into the mountains by ancestors of the Batad indigenous people. The terraces are commonly thought to have been built with minimal equipment, largely by hand. The terraces are located about 1,500 m (5,000 ft) above sea level and cover 10,360 km (about 4,000 mi) of mountainside. They are fed by an ancient irrigation system from the rainforests above the terraces. Evidence of
