El Brujo Archeological Complex located in Magdalena del Cao 60 km / 37 miles from Trujillo, in the Chicama Valley. It is formed by the three following pyramids Huaca Prieta, Huaca Cao and Huaca Cortada. Researchers have found signs of occupation since the pre-ceramic period (5,000 years ago).

These past 10 years of archaeological investigation and conservation work have confirmed the existence of a large ceremonial center whose regional prestige possibly reached 2 millennia back since the construction of temples and sacred areas during the pre-Chavin, Chavin, Salinar and Viru cultural occupation of the Chicama and Moche Valleys. However, the origin of these civilizations in the ceremonial area of the Brujo archaeological complex date from 5,000 years ago, that is pre-ceramic times. The Prieta pyramid is the most important place from these times. In 1946 people from all over the world were surprised with discoveries by Junius Bird, the North American archaeologist.

The Lady of Cao: A female mummy, baptized the Lady of Cao, with complex tattoos on her arms has been found in a ceremonial burial site in Peru. Archaeologists say is one of the best-ever relics of a civilization that ended more than 1,300 years ago.
