Sechín Alto: the largest ceremonial center
A colossal monument of the Sechín culture

Sechín Alto is a true feat of engineering and design dating from the Formative Period. Considered the largest ceremonial complex in ancient America, its colossal scale extends over an area of more than 100 hectares. The site is organized along a north-south axis and its symmetrical design demonstrates rigorous planning. It is estimated that the construction required millions of tons of stone and earth, mobilizing a considerable workforce.

Main characteristics:

• The Main Pyramid: Heart of the complex, this pyramid is the largest artificial mound in Peru. With a base of 250 meters and a height of 44 meters, it dominated the valley and asserted the political and religious authority of the rulers of the time.
• The Plazas and Mounds: The complex is organized around large rectangular plazas and several smaller mounds, which served as centers for ceremonial and administrative activities. This arrangement suggests that the site was much more than just a place of worship, but a true urban center of a highly organized society.
• The Circular Plaza: Like other sites in the Casma Valley, Sechín Alto has a large circular plaza that probably served as a public gathering place for ritual events.

Simply viewing the scale of the site is enough to give an idea of its past importance and the power of the civilization that built it.

Sechín Alto is of capital importance for understanding the Formative Period on the Peruvian coast. Dating from around 1800 BC, it functioned as the main political and religious center of the Sechín civilization. Unlike its smaller neighbor, Cerro Sechín, which was a specialized ceremonial center, Sechín Alto was the heart of power, where decisions were made and the most important rituals took place.

Its role in the valley:

• A Power Center: Its colossal size suggests it was the center of political power that extended throughout the Casma Valley.
• A Link Between Sites: It is considered the central point that connected and coordinated the activities of other sites in the region, including Cerro Sechín.

Visiting Sechín Alto is an impressive experience, but one that requires a bit more preparation than other more developed sites.

• How to get there: The site is located a few kilometers from the city of Casma. As it is a site less frequented by mass tourism, it is recommended to go by taxi or with a local guide.
• Ticket prices: Rates may vary. It is advisable to inquire with a travel agency in Casma to get the most accurate information about entrance fees and access.
• Visit duration: Allow about 2 to 3 hours to explore the entire complex. Due to its size and wilder aspect, be prepared to walk long distances.

Don't forget to bring water, sunscreen, a hat, and sturdy walking shoes, as the site is outdoors and few shaded areas are available.
