Sechin Alto is a massive architectural complex in Peru belonging to the Early Formative period (2000-1500 BC) [1]. It is located in the Casma Province, the Ancash Region, on the left bank of the Sechín River [1]. Archaeologist Julio C. Tello was the first to make a thorough description of this archaeological site during his visit to the valley of Casma in 1937 [1]. The main structure, called "Templo", has a pyramidal shape [1]. It measures 350m by 300m, and reaches the height of 35m [1]. It consists of raised embankments and walls with large stones alternating with smaller ones; conical adobe bricks are seen in the interior [1]. In front of the "Templo" extend five courts or plazas, some with sunken circular courts; this indicates the ceremonial character of the whole complex [1]. The complex is oriented to the northwest, and its length is about 2 km [1].
