In the earthquake-prone central Andes Mountains, there archaeological sites with monumental adobe and stone block structures standing that were built by ancient people hundreds and even thousands of years ago. Clearly, the ancient builders planned to have their important structures last–-and they had the knowledge to build appropriately for their environment. Buildings that promise to last a long time are also being constructed today.
Many ancient cultures revered red, the color of blood and historically associated with danger, courage, and sacrifice. Thousands of years ago in South America, ancient Andean artists happened upon an extremely vivid red dye: cochineal. The use of cochineal continues today, along with lots of controversy.
