Researcher Raúl Bilecky documented at least 16 bedrock-cut platforms at Purulén, a site Walter Alva recorded in northern Peru in the 1970s. Alva proposed a date around 1800 BCE. Bilecky argues that Purulén may be much older—possibly around 11,500 BCE—because of similarities he sees with Huaca Prieta. That date, the proposed solstice alignment and the repeated-tsunami interpretation remain unconfirmed and require archaeological testing and scientific dating.
Raúl Bilecky documents 16 platform pyramids at Purulén in northern Peru

Site mentioned
📍 Puru Lin
Key facts
- Purulén is in Peru's Zaña Valley on the northern coast.
- Bilecky's 2024 field investigation identified at least 16 platforms cut into bedrock.
- Walter Alva recorded the site in the 1970s and proposed a date around 1800 BCE.
- Bilecky argues for a possible date near 11,500 BCE based on perceived similarities to Huaca Prieta; this is not an established date.
- Bilecky interprets the north-northeast orientation as a possible solstice alignment and local deposits as evidence of repeated tsunami inundation; neither interpretation is established by the supplied results.
- Alva's survey recorded chambers that Bilecky encountered sediment-filled, and Bilecky reports little associated pottery.
- A 2024 field-investigation paper is available, so the claim that only modern media documentation exists is inaccurate.
