Ventarrón is a ceremonial temple site on the Reque River about 20 km southeast of Chiclayo, excavated from 2007 onwards and dated to around 2000 BC. The mud-brick platform mound is among the oldest structures ever found on the Peruvian coast, and the painted murals discovered inside — showing a hunting scene with nets and deer — pushed back the timeline for monumental art in the Americas by centuries.
The site suffered a devastating fire in 2017 that destroyed much of the exposed structure and murals, but archaeological work continues and parts of the site are accessible. It receives far fewer visitors than Sipán or the Brüning Museum, which means you often have it largely to yourself. Getting there requires a taxi or tour from Chiclayo; public transport is limited. Combine it with a visit to Huaca Rajada for a full day of Lambayeque Valley archaeology.
