Montegrande, Peru

Montegrande is a ceremonial structure with a spiral shape located near Jaén in the Cajamarca region. The complex spreads over several acres and consists of layered clay and stone arranged in a distinct spiral pattern visible from above.

The site was built around 3000 BCE and shows multiple construction phases indicating it was expanded over many centuries. These early building techniques challenge previous assumptions about how ancient Andean societies developed their architectural knowledge.

The spiral layout reflects the ancient builders' reverence for serpent symbolism in their spiritual beliefs. Walking around the structure, visitors can observe how this curved design connects the ceremonial space to the surrounding landscape.

The site is located in a rural area surrounded by rice fields and pastures and can be reached by local paths. Visitors should bring water and wear appropriate clothing for sun exposure, as there is limited shelter and few facilities on-site.

The structure was protected for thousands of years by a deliberate sealing layer of clay and stones placed by ancient inhabitants. This waterproof covering prevented water damage and kept the construction intact through numerous natural weathering cycles.
