An andén, Spanish for "platform", is a stair-step like terrace dug into the slope of a hillside for agricultural purposes. The term is most often used to refer to the terraces built by pre-Columbian cultures in the Andes mountains of South America. Andenes had several functions, the most important of which was to increase the amount of cultivatable land available to farmers by leveling a planting area for crops. The best known examples of andenes are in Peru, especially in the Sacred Valley near the Inca capital of Cuzco and in the Colca Canyon. Many andenes have survived for more than 500 years and are still in use by farmers throughout the region.
