In Peru, where I come from, an adobe is a brick made of mud mixed with other material such as cane, straw and stone to give consistency. It is dried in the sun. The adobe provides a cool atmosphere to buildings. In Peru, many archaeological places used this material, like the Huaca del Sol, a pre-Columbian construction in Trujillo, which used 100 million adobe bricks. Chan Chan, Huaca Pucllana, and other complexes were also made with adobe. It’s a good material in the dry weather prevalent on the coast of Peru where it rarely rains. Even today, adobe is used for home constructions.
