Its people venerate Santa Maria Magdalena and its day is celebrated on July 22.

Some of the largest prehistoric monuments around the world are situated in the Casma Valley and in the Sechín Valley. The pyramid, main square, and circular sunken courtyard complexes extend over one kilometer in length. In February 2008 archaeologists uncovered a ceremonial plaza which has been dated to 5,500 years ago, making it one of the oldest structures ever found in the Americas.

German and Peruvian archeologists work at the circular 5,500-year-old sunken ceremonial plaza, built of stones and adobe, part of the Sechin Bajo archaeological complex in Casma, Andes foothills, 330 kilometers (210 mi) northwest of Lima, Feb. 2008. The archeologists say the plaza is the oldest known monument in Peru.

Chankillo archaeological site[edit]

Main article: Chankillo

The Thirteen Towers of Chankillo (chanquillo) run north to south along a low ridge within a fourth-century BCE architectural complex in the Casmas valley in north coastal Peru. From hypothesized observing positions within nearby buildings to the west and east, the towers form an artificial, toothed horizon that roughly spans the annual rising and setting arcs of the Sun. The Chankillo towers are interpreted as marking positions of the apparent annual solar movement along the horizon, and as evidencing Sun cults, preceding the Sun pillars of Cusco by almost two millennia.[2][1]
