Findings at Chavín de Huántar indicate that social instability and upheaval began to occur between 500 and 300 BCE, at the same time that the larger Chavín culture began to decline. Large ceremonial sites were abandoned, some unfinished, and were replaced by villages and agricultural land. At Chavín de Huántar, no later than 500 BCE, a small village replaced the Circular Plaza. The plaza was occupied by a succession of cultural groups, and residents salvaged building stones and stone carvings to use in house walls. Multiple occupation floors indicate the village was continuously occupied through the 1940s.
