Nasca society of the south coast of Peru has been interpreted as a sma
ll militaristic empire led from an urban capital called Cahuachi. Rece
nt investigations, however, yielded no data in support of that reconst
ruction. Rather, excavations at Cahuachi revealed the site to be an em
pty ceremonial center with little evidence of a dense, permanent, dome
stic occupation. Yet, in the construction fills of the site's many mou
nds, there is a quantity of refuse, including the remains of ritual pa
raphernalia and quotidian artifacts. The lack of permanent domestic se
ttlement, but evidence of intensive site use, is explained by postulat
ing episodic pilgrimage activities. This model is supported by compari
son of Cahuachi's spatial patterns and material remains to those found
at other Central Andean pilgrimage centers, ancient and modern.
