The site of El Brujo, ("the sorcerer"), at its heyday during the Mochica era, is depicted by three pyramids: Huaca Prieta, Huaca Cao Viejo and Huaca Cortada. It has since risen to fame thanks to Señora de Cao, a mummy found in 2006, whose rich jewellery indicates that she was undoubtedly a lady of rank. Another highlight are the very well-preserved red, blue and ochre friezes, in particular that of the "prisoners" and Aiapaec (Mochica God). Finally, don't miss the site's commendable Cao Museo.
