Sechin Alto, Archaeological site in Casma District, Peru.
The main structure of Sechin Alto stretches 300 meters in length, 250 meters in width, and reaches 35 meters in height, constructed with granite blocks.
Archaeologist Julio C. Tello first documented this site in 1937, determining it was the largest architectural structure in the Americas at that time.
The complex includes five ceremonial courts with sunken circular areas, indicating the religious and social practices of the Sechin-Casma civilization.
The site sits along the Pan-American Highway, allowing visitors to reach it within four hours by car or bus from Lima or Trujillo.
The architectural complex spans 400 hectares, making it five times larger than the ancient city of Caral in Peru.
