The chief example of architecture is the "Chavín de Huantar" temple. The temple's design shows complex innovation to adapt to the highland environments of Peru. To avoid the temple's being flooded and destroyed during the rainy season, the Chavín people created a successful drainage system. Several canals built under the temple acted as drainage. The Chavín people also showed advanced acoustic understanding. During the rainy season water rushes through the canals and creates a roaring sound and creates a noise like a jaguar, a sacred animal. The temple was built of white granite and black limestone, neither of which is found near the Chavín site. This meant that leaders organized many workers to bring the special materials from far away rather than use local rock deposits. They also may have been traded from different civilizations in the area.
