昌昌
Chan Chan is triangular, surrounded by walls. There are no enclosures opening north because the north-facing walls have the greatest sun exposure, serving to block wind and absorb sunlight where fog is frequent. The tallest walls shelter against south-westerly winds from the coast. The walls are adobe brick covered with a smooth surface into which intricate designs are carved. The two styles of carving design include a realistic representation of subjects such as birds, fish, and small mammals, as well as a more graphic, stylized representation of the same subjects. The carvings at Chan Chan depict crabs, turtles, and nets for catching sea creatures (such as Spondylus. Chan Chan, unlike most coastal ruins in Peru, is very close to the Pacific Ocean.
