A central-coast Peruvian culture spread across the Fortaleza, Pativilca, Supe, Huaura, Chancay and Chillón valleys north of Lima, known for distinctive black-on-white pottery, large cotton-and-feather textiles, and cane-and-mud pyramid centers rather than one capital city.
Its southern territories were absorbed by Chimor in the early 1400s, and by roughly 1450-1470 the Inca had occupied the remaining Chancay valleys, ending its independence.
